That tray table is WAYYYYY too big and luxurious - they have shrunk legroom so dramatically now that you get a little sliver about the width of your shoe.
That cup is about double the size they give now.
You didn't get to pick those pretzels, there was just the single "choice" now.
Also, you didn't get to pick that seat and you had to have last minute anxiety that you wouldn't even be assigned a seat by the gate agent at the airport (after already taking time off from work to travel and committing $100+ for uber or airport parking)
You also paid at least an extra $100 to have a carryon bag (more depending on your route) and even more for a checked bag.
your seatback no longer has a screen in it. You have to submit to letting airline gorge on your personal data by granting permissions to run entertainment from your own phone and drain your battery.
Also, though they removed screen and expect you to use your own device, no viable phone holder provided to put your phone in a proper viewing position, so you'll crane and hurt your neck throughout flight.
Also, your base airline ticket is now more expensive than in the past baggie all these upcharges and compromises.
shitty rental car at your destination now costs $100/day and parking at your hotel is not free, and is in fact $30-$50 additional per night.
And your garbage hotel room costs 3X what it should.
It doesn't though with the basic fares now. Boarding pass has "see gate agent" printed where a seat assignment would be. And no guarantee of a couple/family being seated together.
Also always rumors of airlines testing stacked or standing seats to cram even more people in each plane.
Depends on the market probably, but a lot of spots it's like $50-$100 extra, each way, to upgrade to the seat level that let's you choose a seat. Frontier and spirit used to be the joke, but most of them are doing it now. Cliche joke used to be that they'd charge you each time you used the bathroom (maybe they actually happened in Europe, Ryanair?) But like too many things, we're close to living the onion.
