US airlines are pushing to remove protections for passengers and add more fees

I'd be curious to see how the all-in price of airline tickets has evolved in recent decades. It feels like it's now commonplace to have hundreds of dollars in additional fees for things like legroom. That means a cheap ticket is a midrange ticket and a midrange ticket can end up being quite expensive unless you fall for the "we get to strap you behind the bathroom with only the clothes on your back" Saver ticket.

It also means that you're often still out actual money if you use award miles.

Hundreds of dollars for legroom? Are you... sure? For what kind of flights?

US flights (99% of what I have experienced) definitely can get into three figures for anything other than "middle seat, way back". They know there's at least a built-in audience of taller people who will spring for legroom on any flight over an hour. And now that I am old and tall, an aisle seat and legroom are incredibly valuable to me (don't tell 'em, ok?).

Oddly there is no such premium for wide people. I understand (somewhat) price discriminating based on the quantity of space required by the passenger (for comfort or from physical necessity), but then why does this apply to one dimension and not the other.

I'm not even talking about pay-by-weight as was famously tried between pacific islands. Nobody wants to have someone spilling over the armrest into their seat, and I'm sure plenty of people who are wider than the seat would like to fit without going first class. I'm not even so unusually sized, but cannot sit in the aisle without being hit by every person and trolley passing by.

Most airlines require very wide people to buy an extra seat. The requirement is that they have to be able to lower the armrest.
