If you go anywhere by bus, it leaves on time, they don't lose your stuff, if there's an issue there's someone to talk to. shouldn't flying be a bit of a step up?
This is going to sound crazy, but I think air travel has become too cheap. The price wars between airlines has made the margins so thin they have to cut every single corner and pay terrible wages to employees that have no interest in helping you.
Maybe it should be a little more expensive and better quality. Its gotten so bad I think I'd rather take two normal flights per year instead of 3 cheap but traumatic ones.
