Airlines - They are nearly all just a pain in the ass to deal with. When was the last time you heard someone tell you how they had a great experience with an airline?
I'm pretty sure it was a good experience, because I keep reading books about how my trip usually takes months in transit living in your own filth, if you didn't bring your family you'd never see them again, and sometimes you'd die on the way. I had to pay $8 for a sandwich though.
I had a great experience with two airlines recently, bmi and airberlin, but it was probably because i was prepared to pay a little more than my usual easyjet price.
Yeah, i think that it's probably more to do with the correlation of how much you pay to how much you will enjoy airlines though
