100% agree with you. Actually being on the plane is fine, I don't have many complaints there. Yes, there are various compromises around space and comfort, but they're all understandable given the cost/efficiency concerns.

Getting through the airport is just a huge pain in the ass though. At least some airports now let you keep your shoes on again, hopefully soon we'll have scanners that don't need you to remove electronics (I tend to bring too much of this and it's always a pain), or even let you keep liquids again (!).
