You used to be able to carry on one reasonable size bag, and they didn’t stress about it because the total load of luggage / purses / backpacks and so on was fine. You could do what you wanted and they’d fly you where you were going.

Then some genius realized they could charge people $40 for checked bags, so everyone started carrying everything on, so it became a problem and they had to start checking everything at the gate for everyone who didn’t feel like paying the $40 extra for no reason fee, which was the majority of people.

This is just the natural end point of that evolution, where they initiate open hostility to the customer and try to force you into paying $45 more than the ticket price and actively fuck with you to try to bully you into submitting to it.

It’s partially the fault of everyone who just goes on Kayak and hits whatever is the cheapest option. That’s what I do, anyway. Or did, until this week, when I learned my lesson about it.
