Why are there lines at airport security? I mean, we know why the lines form, when passenger load exceeds the capacity, with the bottleneck usually being the X-ray machines. The question is why this imbalance is allowed to happen?
The variable wait at airport security levies a high cost, because passengers must assume it will be long, just in case it is. That means every passenger gets there 15 or more minutes earlier than they would need to, even if there is no wait. Web sites listing wait times can help, but they can change quickly.
For these passengers, especially business passengers, their time is valuable, and almost surely a lot more costly than that of TSA screeners. If there are extra screeners, it costs more money to keep them idle when loads are low, but the passengers would be more than willing to pay that cost to get assuredly short airport lines.
(There are some alternatives, as Orwellian programs like Clear and TSA-PRE allow you to bypass the line if you will be fingerprinted and get a background check. But this should not be the answer.)
In some cases, the limit is the size of the screening area. After 9/11, screening got more intensive, and they needed more room for machines and more table space for people to prepare their bags for all the rules about shoes, laptops, liquids and anything in their pockets.
Here are some solutions:
Appointments at security
The TSA has considered this but it is not widely in use. Rather than a time of departure, what you care about is when you need to get to the airport. You want an appointment at security, so if you show up at that time, you get screened immediately and are on your way to the gate in time. Airlines or passengers could pay for appointments, though in theory they should be free and all should get them, with the premium passengers just paying for appointments that are closer to departure time.
Double-decker X-ray machines
There may not be enough floor space, but X-ray machines could be made double decker, with two conveyor belts. No hand luggage is allowed to be more than a foot high, though you need a little more headroom to arrange your things. Taller people could be asked to use the upper belt, though by lowering the lower belt a little you can get enough room for all and easy access to the upper belt for all but children and very short folks.
A double width deck is also possible, if people are able to reach over, or use the other side to load. (See below.)
This might be overkill, as I doubt the existing X-ray machines run at half their capacity. It is the screener’s deliberation that takes the time, and thus the next step is key…
Remote X-ray screeners
The X-ray screener’s job is to look at the X-ray image and flag suspect items. There is no need for them to be at the security station. There is no need for them to even be in the airport or the city, come to that. With redundant, reliable bandwidth, screeners could work in central screening stations, and be sent virtually to whatever security station has the highest load.
Each airport would have some local screeners, though they could work in a central facility so they can virtually move from station to station as needed, and even go there physically in the event of some major equipment failure. They would be enough to handle the airport’s base-load, but peak loads would call in screeners from other locations in the city, state or country.
Using truly remote screeners creates a risk that a network outage could greatly slow processing. This would mean delayed flights until text messages can go out to all passengers to expect longer lines and temporary workers can come in — or the outage can be repaired. To avoid this, you want reliable, redundant bandwidth, multiple screener centers and the ability to even use LTE cell phones as a backup. And, perhaps, an ability to quickly move screeners from airport to airport to handle downtimes at a particular airport. (Fortunately, there happens to be a handy technology for moving people from airport to airport!)
Screeners need not be working a specific line. Screeners could be allocated by item. Ie. one bag is looked at by screener 12 and the next bag is looked at by screener 24, just giving each item or set of items to the next available screener, which means an X-ray could actually constantly run at full speed if there are available staff. Each screener would, if they saw an issue, get to look at the other bags of the same passenger, and any bag flagged as suspect could immediately be presented to one or more other screeners for re-evaluation. In addition, as capacity is available, a random subset of bags could be looked at by 2 or more screeners.
It can also make sense to just skip having a human look at some bags at random to reduce wait and cost. It might even make sense to let some bags go unviewed in order to have other bags be viewed by 2 screeners. Software triage of how many screeners should look at a bag (0, 1, 2, etc.) is also possible though random might be better because attackers might figure out how to fool the software. With the screeners being remote and the belts operating at a fixed speed, passengers won’t learn who was randomly selected for inspection or not.
Some screeners need to be there — the one who swabs your bag, or does an extra search on it, the one who does the overly-intimate patdown and the one with the gun who tries to stop you if you try to run. But the ones who just give advice can be remote, and the one who inspects your boarding pass can be remote for passengers able to hold those things up to the scanners. I suspect remote inspection of ID is also possible though I can see people resisting that. The scanner who looks at your nude photo can certainly be remote — currently they are out of view so you don’t feel as bothered.
This remote approach, instead of costing more, might actually save money, especially on the national level. That’s because the different time zones have different peak times, and remote workers can quickly move to follow the traffic loads.
It’s also easier with remote screeners for passengers to use both sides of the belt to load and get their stuff. Agents would have to go in among them to pull bags for special inspection, though.
Of course it could be even better
Don’t misunderstand — the whole system should be scrapped and replaced with something that is more flyer-friendly as well as more capable of catching actual hijacker techniques. But if it’s going to exist, it should be possible to remove the line for everybody, not just those who go through background checks and fingerprinting just to travel.
After 2001, a company developed bomb proof luggage containers and now there is a new bag approach which would reduce the need to x-ray and delay checked luggage as much as they do. They were never widely deployed, because they cost more and weigh more.
I have 3 things I carry on planes:
- The things I need on the plane (like my computer, books and other items.)
- The vital and fragile things which I insist not leave my control, such as my camera gear and medicines.
- When I am not checking a bag, everything else for short trips.
I’m open to having all but #1 being put into a bomb-proof container by me and removed by me in a manner similar to gate check, so I can assure it’s always on the plane with me. Of course if I’m to do that then security (for just me and the items of type one) must be close to the plane — which it is for many international flights to the USA. That would speed up that security a lot. The use of remote screeners could make it easier to have security at the gate, too.
Personally, once the problem of taking over the cockpit was solved by new cockpit doors and access policies, I think there was an argument that you need not screen passengers at all. Sure, they could bring on guns, but would be no longer able to hijack the aircraft, so it’s no different from a bus or a train. Kept to small items, they would not be able to cause as much damage as they could do with a suitcase sized bomb in the security line. The security line is, by definition, unsecured, and anybody can bring a large uninspected roll-aboard up to it, amidst a very large crowd — similar to what happened in Moscow in 2011.
Instead, you would have gates where a portal in the wall would have a bomb-proof luggage container into which you could put your personal bags and coats. Most people would then just get on, but a random sampling would be directed to extra security. Those wishing to bring larger things on-board (medical gear, super-fragiles, mega-laptops) would need to arrive earlier and go through security too. A forklift would quickly move the bombproof container into the hold and the plane would take off.

We’ve all learned a lot about what can and can’t be done from the tragic story of MH 370, as well as the Air France flight lost over the Atlantic. Of course, nobody expected the real transponders to be disconnected or fail, and so it may be silly to speculate about how to avoid this situation when there already is supposed to be a system that stops aircraft from getting lost. Even so, here are some things to consider:
In the next few years, Iridium plans to launch a new generation of satellites with 1 megabit of bandwidth, replacing the pitiful 2400 bps they have now. In addition, with luck, Google Loon may get launched and do even more. With that much bandwidth, you can augment the “black box” with a live stream of the most important data. In particular, you would want a box to transmit as much as it could in the event of catastrophic shock, loss of signal from the aircraft and any unplanned descent, including of course getting close to the ground away from the target airport set at takeoff. Even the high cost of Iridium is no barrier for rare use, and you actually have a lot of seconds in the case of planes lost while flying at high altitude. Not enough to send much cockpit voice, but the ability to send all major alerts, odd-readings and cockpit inputs.
You could send more to geosync satellites but I will assume in a crisis it’s hard to keep aimed.
Another place you could stream live data would be to other aircraft. Turns out that up high as they are, aircraft are often able to transmit to other aircraft line of sight. Yes, the deep south Indian ocean may not be one of those places, but in general the range would be 500 miles, and longer if you used any wavelength that could travel beyond the horizon. Out there over the ocean, there’s nobody to interfere with, and closer to land, you can talk to the land. Near land, the live stream would go to terrestrial receivers, even cell towers. Live data gives you information even if the black box is destroyed or lost. If you are sure that can never happen, the black box is enough.
It also could make sense to have the black box be on the outside of the aircraft, meant to break away on impact with ground or water, and of course, it should float. The Emergency Locator Transmitter should be set up this way as well. You want another box pinging that sinks with the plane, though. The floating ELT/black box could even eject itself from the plane on its own if it detected an imminent crash in any remote area, including the ocean. With a GPS, it will know its altitude and location. It could even have a parachute on it.
Speaking of pinging, one issue right now is the boxes only have power for 2 weeks. Obviously there is a limit on power, and you want a strong signal, but it is possible to slow down your ping rate as your battery gets low, to the point that you are perhaps only pinging a few times a day. The trick is you would ping at very specific and predictable times, so people would know precisely when to listen — even years later if they get a new idea about where to look. Computers can go to sleep on these sorts of batteries and last for years if they only have to use power once a day.
If all you want to know is where an aircraft is, we’ve seen from this that it doesn’t take too much. A slightly more frequent accurately timed ping of any kind picked up by 2 satellites (LEO or geosync) is enough to get a pretty good idea where a plane is. The cheapest and simplest solution might be a radio that can’t be disabled that does this basic ping either all the time, or any time it doesn’t get the signal that others systems like ACARS are not doing their job.
Like many, I was surprised that the cell phones on board the aircraft that were left on — and every flight has many phones left on — didn’t help at all. Aircraft fly too high for most cell phones to actually associate with cell towers on the ground, so you would not see any connections made, but it seems likely that as the plane returned over inhabited areas on its way south, some of those phones probably transmitted something to those ground stations, something the ground stations ignored because they could not complete the handshake. If those stations kept lower level logs, there might be information there, but they probably don’t keep them. Because metal plane skins block signals, they might have been very weak. If the passengers were conscious, they probably would have been trying to hold their phones near the window, even though they could not connect at their altitude.
Another thing I have not understood is why we have only seen the results of one ping detected by the Inmarsat over the Indian. From that ping, they were able to calculate the distance of the aircraft to the satellite, and thus draw that giant arc we’ve all seen on the maps. It’s not clear to me why there was only one ping. Another ping would have drawn another arc, and so on, but that would have given us much more data to narrow down the course of the aircraft, as it’s a fair presumption it was flying straight. The reason they know know the one ping came from the southern hemisphere is the satellite itself is not perfectly centered and so moves up and down, giving a different doppler for north vs. south.
We may not learn their fate. I must admit, I’m probably an unusual passenger. I am an astronomer, and so will notice if a plane has made such a big course correction, though I have to admit in the southern hemisphere I would get confused. But then I would pull out my phone and ask its GPS where we are. I do this all the time, and I often notice when the aircraft I am in does something odd like divert or circle. But I guess there are not so many people of this stripe on a typical plane. (Though I have flown in and out of KL on Malaysian Airlines myself, but long ago.)
While hope for the people aboard is gone, I do hope we learn the cause of the tragedy, to see if anything we can think that is not too expensive would prevent it from happening again. The cost need not be that low. The cost of this search and the Air France search both added up to a lot.
Update: A New Idea — as soon as the search zone is identified, a search aircraft should drop small floating devices with small radio transmitters good to find them again at modest range. Drop them as densely as you can, which might mean every 10 miles or every 100 miles but try to get coverage on the area.
Then, if you find debris from the plane, do a radio hunt for the nearest such beacon. When you find it, or others, you can note their serial number, know where they were dropped, and thus get an idea of where the debris might have come from. Make them fancier, broadcasting their GPS location or remembering it for a dump when re-collected, and you could build a model of motion on the surface of the sea, and thus have a clue of how to track debris back to the crash site. In this case, it would have been a long time before the search zone was located, but in other cases it will be known sooner.

Southwest recently announced a very different approach to providing in-flight entertainment. Partnering with dish network they will offer live TV and on-demand programming over the in-plane WIFI to people’s personal devices. Sadly, for now, it’s just Apple devices. I will presume they will extend this to other platforms, including laptops, soon, and they should consider also allowing you to rent a tablet one-way if you don’t have your own.
Everywhere else, we see airlines putting in “fancy” and expensive in-flight entertainment systems. In coach they use small screens in the headrests, and business class and 1st class seats have fairly large displays. I’ve tried a number of these, and uniformly, in spite of all the money, they suck compared to just having pre-loaded video on your own tablet, laptop or DVD player. Even your phone with its small screen is better. Why?
- Almost every one of the systems I’ve seen has been badly written and underpowered, resulting in atrociously slow response time and poor UI
- The ones that charge you sit there all flight advertising to you if you don’t pay. Clever people can figure out how to turn off the screen, but it doesn’t matter, because most of the other screens are this very distracting synchronized spam video. Worse, during boarding, they turn up the audio on this ad.
- They pause your video for every little announcement, including non-safety announcements, spam to shop duty free or join the FF club, and translations of announcements into other languages. I can almost accept doing this for safety announcements (I would rather take a safety quiz online or at my seat and be free from the routine ones) but if you start your movie before take-off (which is a nice thing to do) you will be interrupted literally dozens of times.
- The video, game and music selections are often quite lame compared to what you can get in any online store for your phone or tablet
- The live TV has advertising in it, and you can’t FF or get up for a snack like at home. Unless its news or sports, why watch live?
- There is often a surprisingly large box under the seat in every seat cluster for the in-flight computer. That takes away foot room and storage space and adds weight to the plane. Plus, why are the boxes so large — consider these devices seem to have far less power than a typical tablet?
- If they have a touchscreen, the guy behind you is always pushing on the back of your seat. Otherwise they have a fairly hard to use hand remote (and for unknown reasons, long latency on button pushes.)
- Disturbingly, movies are often played in the wrong aspect ratio on these screens, and you can’t do anything about it but watch fat characters.
- The small screen ones tend to be fairly low resolution, mostly because they are older. Your phone or tablet is usually not that old and has HD resolution.
That’s a pretty astonishing list of failings. Your own tablet has one main downside — they force you to shut it off on takeoff and landing, for no good reason since tests all show a tablet does not interfere with the plane. It also may have battery limitations, though those are fixed with a USB charge port in the seatback. You do need to bring a stand for it, it would be nice if there were something on the seatback to mount your tablet. You would need an app to do plane-related stuff like the moving map or safety training.
What’s amazing is that all the other airlines have paid a lot of money to install these bad systems, and more to the point carry the weight of them everywhere. This is the classic battle between custom technology, which gets obsolete very quickly, and consumer technology like phones and tablets which are generic but replaced frequently so always modern. The consumer tech will always win, but people don’t realize that.
At first, they might have worried that they needed to provide a screen for everybody. This could easily have been solved with rentals, both out in the terminal and to a lesser extent on-board. Especially if you put in power jacks so recharge is not an issue.
Today the airlines would all be wise to tear out their systems and follow Southwest. I don’t care about the Dish Network streaming that much, but better (and more popular) would be on-board servers which offer a local version of the Google Play store and iTunes store containing the most popular movies and new releases. I venture those companies would be OK with providing that if allowed, and if not, somebody else would.
As a side note, let me say that it would be nice if the online movie stores offered a form of rental more amenable to flying. Most offer a 24 hour rental, which starts when you start playing (so you can download in advance.) However, they don’t offer the ability to start a movie on your flight out and finish it on your flight back. So you dare not start a rental movie unless you are sure you are going to finish it on the flight. Another case where the DRM doesn’t really match what people want to do. (I don’t want to “buy” the movie just to finish it later.)
I will admit one nice feature of the rental is that if I am on a flight, I can watch a movie, and that activates the same 24 hour rental period at home, so those at home can watch it there too. That way, if there is a movie we all wanted to see, we can all see it — if those at home are willing to watch it that particular day.

Just returned from an overseas trip to Moscow, I am reminded of the rant I posted earlier about the constant interruptions on the in-flight entertainment system.
Everything I said before remains valid:
- Know me by my flyer number and don’t repeat things to me I’ve already certified as knowing, like safety rules
- Know my language (I input it, after all) and don’t bother me with announcements other than in my best understood language
- Show me most things as text, perhaps in a crawl under my show. If need be, have me confirm I understand.
- Tailor the message to my age and my location in the plane. Show me exits on the screen for my seat.
- Cut back on the spam about how great your airline is, how wonderful the FF plan is or why I should buy duty free.
Today, instead you can see the visible frustration on the faces of flyers as their movie is interrupted so that they can here the translation into Russian of the long announcement they just heard in German and English.
Having good custom in-flight entertainment is good, and considered a major competitive feature, but already I see more and more people preferring to put out a tablet, even when they have a super-fancy system in the first-class seats. The tablet of course does not have the interruptions (even for the tiny number of real announcements such as in our case last week, “we can’t get the landing gear doors to close so we’re dumping fuel and returning to the airport”) and it also has, if you prepare it, customized entertainment that you know you want to watch.
Frankly, I am not sure who programs the video selections on many of the airlines but I have to suspect they don’t just try to get the best movies with good reviews. They either try to get the cheapest movies or have deals with certain studios — it’s amazing how few quality films they might have in a selection of 100 movies.
I also remain disappointed at how badly implemented most of the in-flight systems I have seen. They are all slow, with highly noticeable lags after keypresses, poor touchscreens, freezes and crashes. Any tablet or phone puts them to shame when it comes to UI and responsiveness. And to top it off, they are huge — on main airlines, many of the seats have reduced footroom to fit the box for the video system. (It also has other in-seat electronics I presume but still, it’s about 10x bigger than it needs to be.) This is odd particularly since in planes floor space and weight are at such a premium. A tablet computer, either fixed in the seat or on an anti-theft power/data tether, would provide a better system — smaller, lighter, better UI, cheaper, better screen — in just about every way. Of course when they first designed these seats years ago they did not have cheap tablets but there is little excuse to continue installing the old ones.
Wait, how could they have known? How could they have not known. It’s 2012. We’ve known for decades now that each year computer products get smaller, faster, cheaper and superior in major ways. When you are designing a system to install in the future, it’s a mistake to design it based on the current technology. You should bet that something better will be along and make your design adaptable to it. If nothing else your standard design is going to get faster and higher resolution — which makes the slow response time of the existing systems inexplicable.
Many airlines are starting to offer satellite TV. That’s better than the old limited selections (or in particular a single bad movie) but actually not too appealing. Aside from being full of commercials and ignoring your schedule, with TV the announcements and interruptions make you miss crucial parts of your show as they talk over them. More than once I’ve been watching a show on an airline to have them talk over the climax of the film.
I’m whining a lot but it’s because I do believe this is important. Truth is that on a flight you are often tired and cramped, and reading and working are not tremendously comfortable. I bring a book but read at a reduced speed. Having nice noise-cancelling headphones and a good in-flight entertainment system with quality content can make a make a flight much better, and it’s a shame that so many things are obviously wrong with the systems they have built. Today’s flights are stressful in any cabin, and a quiet and uninterrupted experience would do a lot to increase customer satisfaction.

Two recent flight booking experiences on United Airlines:
a) I booked a round trip to Toronto with miles. Due to new plans, I ended up getting a different flight to Toronto but wanted to take the same flight back. I had booked return tickets for 2 passengers, but you can book one-way tickets for the same miles price, and you can book passengers together or independently (later joining the reservations to sit together.) It doesn’t cost any more to get 4 single legs, it’s just a lot more work for you and the airline.
When I needed to change it, they said, no, there was no way to just use the return leg. I must cancel or not use the entire trip. To cancel and re-credit the miles is $250 for 2 passengers — so much for free. To re-book the one-way leg another $200 or so. The original booking was $125 in fees. That’s a bunch. Had I booked it as independent trips, I could have used my return leg, and just refunded or re-used the outgoing leg. I decided to re-use the whole trip and buy a paid fare ticket. Perhaps that’s what they wanted, but now if I want flexibility I must jump through hoops booking, and make them jump too.
b) The alternate trip was to Brussels. I booked a flight with one flight number that stops and changes flights in Chicago. It’s really two flights but with one number. Many other alternatives existed that were really two flights with different numbers. On checking in, I found that there were business class seats available. Normally on United, if you have status, that means a complimentary upgrade to busines class on the domestic flights. But because I booked it as one flight, I have no domestic flight. Other people on the same flight to Chicago with me are getting upgraded because they are not flying on to Europe while I’ll sit in coach. It’s not a long flight, but still. Next time, never book a single flight unless that’s what you really want, which you may do if it’s the same plane and that reduces your risk of lost luggage and gets you better seats. In this case, there is no advantage to the single flight number it seems, and a big loss.
Of course, phone staff have no power to make things right. Sigh.
End of rant.

A new paper on trusted traveler programs from RAND Corp goes into some detailed math analysis of various approaches to a trusted traveler program. In such a program, you pre-screen some people, and those who pass go into a trusted line where they receive a lesser security check. The resources saved in the lesser check are applied to give all other passengers a better security check. This was the eventual goal of the failed CLEAR card — though while it operated it just got you to the front of the line, it didn’t reduce your security check.
The analysis shows that with a “spherical horse” there are situations where the TT program could reduce the number of terrorists making it through security with some weapon, though it concludes the benefit is often minor, and sometimes negative. I say spherical horse because they have to idealize the security checks in their model, just declaring that an approach has an X% chance of catching a weapon, and that this chance increases when you spend more money and decreases when you spend less, though it has diminishing returns since you can’t get better than 100% no matter what you spend.
The authors know this assumption is risky. Turns out there is a form of security check which does match this model, which is random intense checking. There the percentage of weapons caught is pretty closely tied with the frequency of the random check. The TTs would just get a lower probability of random check. However, very few people seem to be proposing this model. The real approaches you see involve things like the TTs not having to take their shoes off, or somehow bypassing or reducing one of the specific elements of the security process compared to the public. I believe these approaches negate the positive results in the Rand study.
This is important because while the paper puts a focus on whether TT programs can get better security for the same dollar, the reality is I think a big motive for the TT approach is not more security, but placation of the wealthy and the frequent flyer. We all hate security and the TSA, and the airlines want to give better service and even the TSA wants to be hated a bit less. When a grandmother or 10 year old girl gets a security pat down, it is politically bad, even though it is the right security procedure. Letting important passengers get a less intrusive search has value to the airlines and the powerful, and not doing intrusive searches that seem stupid to the public has political value to the TSA as well.
We already have such a program, and it’s not just the bypass of the nudatrons (X ray scanners) that has been won by members of congress and airline pilots. It’s called private air travel. People with their own planes can board without security at all for them or their guests. They could fly their planes into buildings if they wished, though most are not as big as the airliners from 9/11. Fortunately, the chance that the captains of industry who fly these planes would do this is tiny, so they fly without the TSA. The bypass for pilots seems to make a lot of sense at first blush — why search a pilot for a weapon she might use to take control of the plane? The reality is that giving a pass to the pilots means the bad guy’s problem changes from getting a weapon through the X-ray to creating fake pilot ID. It seems the latter might actually be easier than the former. read more »

I have written before about letting passengers pay for an empty middle seat next to them and recently about ANZ’s cuddle class and related programs which partially implement this.
While I believe airlines could sell the empty middle for somewhere in the range of 30-40% of a regular ticket, this still has issues. In particular, are they really going to bump a poor standby passenger who had a cancelled flight and make them stay another night so that people can get a more comfortable seat?
One idea is to allow the sale of empty middles by dutch auction. In effect this would say, “If there are going to be empty middles on this plane, those who bid the most will get to sit next to them.” If this can be done, it’s a goldmine of extra revenue for the airline. What they sell costs them nothing — they are just selling the distribution of passengers on the plane. If the plane fills up, however, they sell it all and nobody is charged.
The dutch auction approach would let each passenger make an offer. If there are 5 empty middles, then the 10 people who sit next to them win, but they all pay the 10th highest bid price. If only 9 passengers bid, the 10th highest price is zero, and everybody pays zero — which is what happens today, except it’s semi-random. While this may seem like a loss for the airline, many game theory tests suggest that dutch auctions often bring the best result, as they make both sides happy, and people bid more, knowing they will actually pay the fair price if they win.
(On the other hand, airlines are masters at having two people pay vastly different prices for exactly the same thing and have managed to avoid too much resentment over it.)
There is one huge problem to solve: How do you arrange that matched bidders are sitting together to share the empty middle? Each empty middle benefits two passengers. read more »

Some years ago I made the proposal that airlines sell half of a middle seat at half price or less so that two coach passengers could assure they would have an empty middle next to them.
I learned a while ago about one approach to this plan, a new “cuddle class” from Air New Zealand also known as the skycouch. It’s a row of 3 coach seats that folds down into a very narrow and short bed for two. The idea is that couples can book the whole row for 2.5x the cost of one seat, ie. the empty middle is being sold at a pretty reasonable half-price, or 1/4 price per person.
As I noted earlier, that alone would be worthwhile. Many people would gladly pay 25% more for an aisle or window with a guarantee that nobody was in the middle, and would get together with other solo voyagers to do this. Air New Zealand has for some time offered what it calls the “Twinseat” which is the ability to buy (for a fairly low price around $60) an assured empty adjacent seat “subject to availability.” This is something different — it’s simply saying that, if there are going to be empty middles on the plane anyway, the people who pay more at the gate will get those next to them. You can’t assure it on a flight unless you make sure you take a flight that won’t fill up.
This skycouch seat however has armrests that really go all the way up, and a footrest that comes up to make the whole thing a platform. Frankly, since 3 seats is only 4.5’ long and the bed is narrower than a twin bed, you need a couple that sleeps together very comfortably while spooning. While everybody likes doing that for a little while, it’s fewer who can do that for a whole night. One person could buy the whole row, I guess, but at 2.5x it starts to approach a nice business class seat, many of which now lie flat. (Mind you I’m picky enough that I don’t sleep that well in the business class flat seats, and I have yet to want to pay for the 1st class ones.)
It’s nice to the see the innovation, though. I mean some airlines even have coach armrests that don’t go up all the way when reclined, and that’s a real pain for couples who want to relax together even in the old seating designs.
What would be more interesting, if less romantic, would be a way to have a portable platform that could be installed on top of this row to turn it into two bunkbeds. From a physical standpoint, you could have 4 slots for poles, some reinforcing straps to form X braces on the poles, and a board with inflatable mattress on the top, such boards packed somewhere compactly in the ceiling when not in use. The poles would have to go up and hold a net and bars to stop the top bunkmate from falling out. But the hard part would be making this strong enough to qualify as safe in an emergency landing, since an emergency might arise while these are still assembled, though they would all be dismantled well before landing and they would only be used on flights 10 hours and up. If there were a section of these you could help it along by having no recline in these seats so the seat backs are solid and able to support the upper berth.
In this case, you could have strangers happily paying 125% of the base ticket price for one of these bunks. Lot of work to set up and tear down, though. Probably need a weight limit in the upper bunk. If you can do it at all.

Like just about everybody, I hate the way travel through airports has become. Airports get slower and bigger and more expensive, and for short-haul flights you can easily spend more time on the ground at airports than you do in the air. Security rules are a large part of the cause, but not all of it.
In this completely rewritten essay, I outline the design on a super-cheap airport with very few buildings, based on a fleet of proto-robocars. I call them proto models because these are cars we know how to build today, which navigate on prepared courses on pavement, in controlled situations and without civilian cars to worry about.
In this robocar airport, which I describe first in a narrative and then in detail, there are no terminal buildings or gates. Each plane just parks on the tarmac and robotic stairs and ramps move up and dock to all its doors. (Catering trucks, fuel trucks and luggage robots also arrive.) The passengers arrive in a perfect boarding order in robocars that dock at the ramps/steps to let them get on the plane through every entrance. Luggage is handled by different robots, and is checked and picked up not in carousels and check-in desks, but at curbs, parking lots, rental car centers and airport hotels.
The change is so dramatic that (even with security issues) people could arrive at airports for flights under 20 minutes before take-off, and get out even faster. Checked luggage would add time, but not much. I also believe you could build a high capacity airport for a tiny fraction of the cost of today’s modern multi-billion dollar edifices. I believe the overall experience would also be more pleasant and more productive for all.
This essay is a long one, but I am interested in feedback. What will work here, and what won’t? Would you love to fly through this airport or hate it? This is an airport designed not to give you a glorious building in which to wait but to get you through it without waiting most of the time.
The airport gets even better when real robocars, that can drive on the streets to the airport, come on the scene.
Give me your feedback on The Robocar Airport.
Key elements of the design include: read more »

Here’s an idea that seems a bit wild and scary at first, but it’s doable today and has broad benefits: Small aircraft that don’t have landing gear, but instead land and take off from robotic “can’t miss” platforms pulled by cables on short airfields.
For every small aircraft purchaser, a big decision is whether to get retractable landing gear. They are very expensive, and create a risk of failure, but your plane will fly a lot faster and be more fuel efficient if you get them. What if we could leave the landing gear on the ground?
Imagine a wheeled platform on the runway with robotic control and a variety of systems to perfectly track an approaching aircraft. Pulled by cables, it can accelerate at several “g”s forward and back and left and right. As the aircraft approaches it tracks it and the cockpit display indicates positive lock. If the plane veers left, it veers left. If the plane speeds up it speeds up. Pretty much no matter what the pilot or winds do (other than missing the runway entirely) the plane can’t miss landing on it. It’s spring loaded so even if the landing is a bit hard the shock is cushioned. Done right, it’s just like having fancy shock absorbing landing gear. read more »

Just back from some time on the road, which always prompts me to think of ways to improve travel.
First, and most simply: Every hotel room comes with a small foldable stand on which to put your suitcase. The problem is they all come with exactly one of these. In some rooms there is space on the tables or dresser for another bag, but often there is not. Doing solo business travel I have just one bag, but all couples, and many solo wanderers have more than one, and so you end up putting bags on the floor. It’s quite annoying, since these stands can hardly be very expensive — folding cloth and metal chairs can be had for $10 in most stores. I’ve only tried once or twice to ask housekeeping for another, and been surprised to learn they don’t keep spares. Frankly, I think it would be cheaper to just put 2 in every room than waste staff time delivering extras, but either would work. And the hotel often knows if a room is booked for 2 rather than one in advance. If you have a bellman take up your bags, not only does the bellman see how many bags you have but it’s a sure thing you have several. Every bell station should have some extra racks and throw what is needed on the luggage cart.
Next, I think it would be interesting to see car rental companies develop cars just for road trips. They are the largest buyers of cars (and often owned by car companies) so custom cars are not out of the question. SUVs and some minivans contain many of the features of a road trip car, but they are often 3 times as expensive when reserved in advance, and 1.5x to 2x more expensive in gasoline usage. What features might a road trip car have? read more »

Everybody knows about the Jet Blue attendant who flew off the handle when he got hit in the head by a bag and had fights with passengers over stored carry-ons. And we know airlines are starting to charge higher fees for checked bags (and even carry-ons) which netted them over $700 million last year. This pushes more people to want to use carry-on bags, which we already wanted to save time, and that means more waits at security and more waits getting on and off flights.
I admit to being a heavy user of carry-on bags. For one thing I usually have lots of camera equipment with me which is too fragile to check unless I have bulky foam cases. Which they then might lose, and which means getting to the airport around 20 to 30 minutes earlier and leaving it 15 minutes later with several more bags. (And perversely, paying more on some airlines.)
The system is getting stretched. I’ve often thought about one useful solution, which would be standardized carry-on bag racks with rails. The standard sized bags would quickly slick in and click-lock in place. No doors even (except for aesthetics) and no fussing with overhead bags, or rearranging. Perhaps some small unstructured place on top or between for coats and purses and laptop bags but mostly they would go under the seat, or in the seat pocket. (Currently they are not permitted in the seat pockets but these could be strengthened and given a closure so the computer can’t fly out in a crash.)
Add to this a system of official gate-check racks. These racks would be there at the gate or in the jetway. If need be they would be mounted in a special elevator or forklift so that they can be quickly and reasonably gently inserted and removed in the cargo hold. These racks would include some rails for standardized bags (especially on puddle-jumper planes which can’t have as many overhead rails) and some amorphous sections with strong cargo netting. They would have shock absorbers to reduce shocks when they are put on the plane or taken out. You would place your items in these racks yourself — in parallel with other passengers, in a wide space where doing so is not blocking others — and the goal would be that you could put semi-fragile items, including things like cameras and laptops into the racks with full confidence. To help with this, we could have a camera on the wing which feeds the seatback screens so that passengers could watch this module as it is loaded and unloaded. This would do a lot to ensure that it is treated with care in a way that checked luggage often is not. read more »

Last week, on my trip to Berlin, I managed to drop my passport. I don’t know where — it might have been in the bathroom of Brussels airport trying to change clothes in a tiny room after a long red-eye, or it might have been when Brussels Air made me gate check a bag requiring a big rearrangement of items, or somewhere else. But two days later, arriving at a Pension in Berlin I discovered it was missing, and a lot of calling around revealed nobody had turned it in.
In today’s document hungry world this can be a major calamity. I actually have a pretty pleasant story to report, though there were indeed lots of hassles. But it turned out I had prepared for this moment in a number of ways, and you may want to do the same.
The upshot was that I applied for a passport on Wednesday, got it on Thursday, flew on Friday and again on Monday and got my permanent
passport that same Monday — remarkable efficiency for a ministry with a reputation for long bureaucracy.
After concluding it was lost, I called the Canadian Embassy in Berlin. Once you declare the passport lost, it is immediately canceled, even if you find it again, so you want to be sure that it’s gone. The Embassy was just a couple of U-bahn stops away, so I ventured there. I keep all my documents in my computer, and the security guy was shocked I had brought it. He put all that gear in a locker, and even confiscated my phone — more on that later. read more »

Since I’m on the road (Washington DC right now, then Berlin on Monday for a few days and then Toronto for the weekend of the 11th) I will lament on the problem I have noted before in travel power. We have to carry so many chargers. I have also found it’s a pain to take them all out and put them back in again.
So how about an electrified rollaboard travel bag. It would plug in, and of course you would have the right adapters for the countries you are going to. Then, along the bottom it would offer a power strip of sorts, with receptacles for your home plug form. The back of these units tends to have spare room due to the bars.
It would also feature an internal USB powering hub, with a few USB jacks, but also built in would be some retractable cables with micro-usb (the new power standard for phones and some other devices) or mini-usb if you still need that. (Alternately have one and adapters for the other.)
Next a universal battery charger. They sell these now with plates that adapt to the various camera batteries, and they even have plates for nimh AA batteries etc. Perhaps even 2 plates.
And of course a universal laptop power supply, but this needs a somewhat long cord. Now I know, you need a power supply to carry with the laptop to meetings, so do you want to carry two? Perhaps not, but I actually like to when space is not super tight. It’s possible this supply could be done in a way that it can snap out, and so all you carry is an extra wall cord. Since I like retractables however you might want another laptop cord and special tip for it.
The advantage: One thing to plug in and unplug when you go from room to room.
And the fact that the wheelies, because of their carry handle, tend to have some extra room to put stuff if it is built in.
The downside: Standards change and your wheelie could get obsolete. The x-ray people may take a bit of time to get used to it as well.

I recently stayed at the home of a friend up in Vancouver. She had some electrical wiring problems, and since I know wiring, I helped her with them as well as some computer networking issues. Very kindly she said that made me a houseguest from heaven (as opposed to the houseguests from hell we have all heard about.) I was able to leave her place better than I found it. Well, mostly.
This immediately triggered a business idea in my mind which seems like it would be cool but is, alas, probably illegal. The idea would be a service where people with guestrooms, or even temporarily vacant homes, would provide free room (and board) to qualified tradespeople who want to have a cheap vacation. Electricians, handypeople, plumbers, computer wizards, housepainters, au pairs, gardeners and even housecleaners and organizers, would stay in your house, and leave it having done some reapirs or cleanup. In some cases, like cleanup, pool maintenance and yard sweeping, the people need not be skilled professionals, they could be just about anybody.
Obviously there would need to be a lot of logistics to work out. A reliable reputation system would be needed if you’re going to trust your house to such strangers, particularly if trusting the watching of your children. You would need to know both that they are able to do the work and not about to rob you. You would want to know if they will keep the relationship a business one or expect a more friendly experience, like couch surfing.
In addition, the homeowners would need reputations of their own. Because, for a skilled tradesperson, a night of room and board is only worth a modest amount of work. You can’t give somebody a room and expect them to work the whole day on your project — or even much more than an hour. Perhaps if a whole house is given over, with rooms for the person and a whole family, more work could be expected. The homeowner may not be good at estimating the amount of work needed, and come away disappointed when told that the guest spent 2 hours on the problem and decided it was a much bigger problem.
Trading lodging for services is an ancient tradition, particularly on farms. In childcare, the “au pair” concept has institutionalized it and made it legal.
But alas, legality is the rub. The tax man will insist that both parties are making income and want to tax it, as barter is taxable. The local contractor licencing agency will insist that work be done only by locally licenced contractors, to local codes, possibly with permits and inspections. And immigration officials will insist that foreign tourists are illegally working. And there would be the odd civil disputes. An unions might tell members not to take work even from remote members of cousin unions.
The civil disputes could be kept to a minimum by making the jobs short and a good deal for the guests, since for the homeowners, the guest room was typically doing nothing anyway — thus the success of couch surfing — and making slightly more food is no big deal. But the other legal risks would probably make it illegal for a company to get in the middle of all this. At least in the company’s home country. A company based in some small nation might not be subject to remote laws. read more »

I love online check-in, and printing your boarding pass at home to avoid doing anything but going to the gate at the airport. Airlines are even starting to do something I asked for many years ago and sending a boarding pass to the cell phone that can be held up to a screen for check-in.
But if they can’t do that, I want them to let me to print my boarding pass long before my flight. In particular, to print my return boarding pass when I print my outgoing one. That’s because I have a printer at home but often don’t have one on the road.
Of course, you can’t actually check in until close to the flight, so this boarding pass would be marked as preliminary, but still have bar codes identifying what they need to scan. On the actual day of the flight, I would check in from my phone or laptop, so they know I am coming to the plane. There’s no reason the old boarding pass’s bar codes can’t then be activated as ready to work. Sure, it might not know the gate, and the seat may even change, but such seat changes are rare and perhaps then I would need to go to a kiosk to swap the old pass for a new one. If the flight changes then I may also need to do the swap but the swap can be super easy — hold up old pass, get new one.
I could also get a short code to write on the pass when I do my same-day check-in, such code being usable to confirm the old pass has been validated.

One of the world’s favourite (and sometimes least favourite) topics is the issue of terrorism and security. On one side, there are those who feel the risk of terrorism justifies significant sacrifices of money, convenience and civil rights to provide enough security to counter it. That side includes both those who honestly come by that opinion, and those who simply want more security and feel terrorism is the excuse to use to get it.
On the other side, critics point out a number of counter arguments, most of them with merit, including:
- Much of what is done in the name of security doesn’t actually enhance it, it just gives the appearance of doing so, and the appearance of security is what the public actually craves. This has been called “Security Theatre” by Bruce Schneier, who is a friend and advisor to the E.F.F.
- We often “fight the previous war,” securing against the tactics of the most recent attack. The terrorists have already moved on to planning something else. They did planes, then trains, then subways, then buses, then nightclubs.
- Terrorists will attack where the target is weakest. Securing something just makes them attack something else. This has indeed been the case many times. Since everything can’t be secured, most of our efforts are futile and expensive. If we do manage to secure everything they will attack the crowded lines at security.
- Terrorists are not out to kill random people they don’t know. Rather, that is their tool to reach their real goal: sowing terror (for political, religious or personal goals.) When we react with fear — particularly public fear — to their actions, this is what they want, and indeed what they plan to achieve. Many of our reactions to them are just what they planned to happen.
- Profiling and identity checks seem smart at first, but careful analysis shows that they just give a more free pass to anybody the terrorists can recruit whose name is not yet on a list, making their job easier.
- The hard reality is, that frightening as terrorism is, in the grand scheme we are for more likely to face harm and death from other factors that we spend much less of our resources fighting. We could save far more people applying our resources in other ways. This is spelled out fairly well in this blog post.
Now Bruce’s blog, which I link to above, is a good resource for material on the don’t-panic viewpoint, and in fact he is sometimes consulted by the TSA and I suspect they read his blog, and even understand it. So why do we get such inane security efforts? Why are we willing to ruin ourselves, and make air travel such a burden, and strip ourselves of civil rights?
There is a mistake that both sides make, I think. The goal of counter-terrorism is not to stop the terrorists from attacking and killing people, not directly. The goal of counter-terrorism is to stop the terrorists from scaring people. Of course, killing people is frightening, so it is no wonder we conflate the two approaches. read more »

On a recent trip on a plane equipped with personal inflight video screens for each seat, I decided to watch a movie quickly and then have a nap. So I started watching the movie right after settling into the seat, about 20 minutes before takeoff. I figured with that I would watch the 1:30 minute movie through the meal service and be ready for the nap about an hour into the flight. What I learned instead was a greater awareness of just how many announcements there are on a typical flight these days. That’s because the in-flight system paused the video with each announcement and put it through my noise cancelling headphones.
The many announcements included:
- The routine ones about the process of takeoff. Door closing. Seatbelt sign on. Various blah-blah-blah
- The huge array of safety announcements and instructions I’ve seen literally hundreds of times.
- A very few useful announcements: Destination check, reasons for delay, updates on flight time.
- Some possibly useful announcements (cell phones off now, OK to use electronics now.)
- Ads: Join our frequent flyer program, get our frequent flyer card, shop from the duty free cart, buy meals, buy drinks (which did not even apply to those not in coach.)
The cacophony is getting worse, almost as bad as when you’re sitting in the terminal with the endless announcements. They know people hate that in the terminals and offer the paid lounge with no announcements, but I’ve said they should just use cell phones instead and give us peace. On Japanese Shinkansen, they also offer a “quiet car” with no announcements — it is up to you to set your own alarm to make sure you don’t miss your stop if you want to sleep or relax. The trains are so on-time you can do this.
How about doing something like this, at least on a modern airplane where you have a personal screen for each seat? read more »

I recently went to the DLD conference in Germany, briefly to Davos during the World Economic Forum and then drove around the Alps for a few days, including a visit to an old friend in Grenoble. I have some panoramic galleries of the Alps in Winter up already.
Each trip brings some new observations and notes.
- For the first time, I got a rental car which had a USB port in it, as I’ve been wanting for years. The USB port was really part of the radio, and if you plugged a USB stick in, it would play the music on it, but for me its main use was a handy charging port without the need for a 12v adapter. As I’ve said before, let’s see this all the time, and let’s put them in a few places — up on the dashboard ledge to power a GPS, and for front and rear seats, and even the trunk. And have a plug so the computer can access the devices, or even data about the car.
- The huge network of tunnels in the alpine countries continues to amaze me, considering the staggering cost. Sadly, some seem to simply bypass towns that are pretty.
- I’ve had good luck on winter travel, but this trip reminded me why there are no crowds. The weather can curse you, and especially curse your photography, though the snow-covered landscapes are wonderful when you do get sun. Three trips to Lake Constance/Bodenzee now, and never any good weather!
- Davos was a trip. While there was a lot of security, it was far easier than say, flying in the USA. I was surprised how many people I knew at Davos. I was able to get a hotel in a village about 20 minutes away.

I’ll have many more observations about my recent trip to DLD, Davos and the Alps soon, but one thing I’ve decided I do want to find (or train) is a travel agent/helper who can assist well with unscheduled travel (ie. a road or railpass trip.)
With unscheduled travel, you don’t know in the morning where you will end up that night. You only figure it out later in the day. Sometimes you just drive until it starts getting late and then you pick where you will end the night. It’s hard (or expensive) to do this in high season but in low season you can always find a room, and I and many others like that sort of freedom.
So when you do pick where you want to end up you have a few options:
- You can have a guidebook or database (such as AAA in the USA) and phone around places until you get something you like
- You can hunt around for web access (better if you have a data plan on your phone) and use sites like TripAdvisor and the various booking search engines (like Kayak/Sidestep) to find a decent hotel at a good price.
- You can just drive into town and look for Vacancy/Zimmer Frei signs and go in and ask the price.
- You can find somebody to do this for you.
There are problems with all these approaches. Method 3 (especially using tripadivsor) helps you avoid turkey hotels and find the better values. However, the databases cover only a fraction of the hotels, and the online reservations systems also cover only a small fraction of hotels in an area. There will be better values out there. On the other hand, many hotels offer a better price through the internet than if you call them, or will charge even more if you just walk in. read more »
