> though in truth we should only hate it when it makes us pay more.

I beg to disagree. I hate 'differential pricing' because I don't find it ethical a bit. A cheap ticket won't make me change my mind. Same product/service must cost the same for all.

And 'differential pricing' can't be neutral if it maximizes profits, that is if it's working for the company practicing this, it means it's not neutral for the people.

I think differential pricing must be made illegal, and that will solve the flexibility problem for good.
