I'm willing to wager that if there was an airline that had "normal" seats with a lot of space, a "good" in flight meal, with friendly staff, and as little hidden nickel and dime charges as possible, it could do really well for itself by word of mouth alone, even if the advertised price as much as double. (What do I know though, it didn't work particularly well for JC Penneys)

People shit all over airlines, all the time. I've only flown a handful of times, but it was the worst transit experiences of my life, I enjoyed the greyhound bus more, and the greyhound was a third the price.
