I fly quite a bit, and I don't enjoy it at all anymore. The employees are frequently surly and the service is minimal. I understand they're trying to stay in business by cutting costs, but for what I pay to fly I expect to be treated a little better. You have to learn how to approach these people to get what you want- anger never works, it pays to be patient and calm.
It seemed for a while like there were fewer seats in the planes, which created more legroom, but that seems to have changed. The seats are really crammed in there now, and it's not comfortable at all (I'm 6'3"). If I was a foot shorter I'd be much better off.
Flying is a neccesary evil, unfortunately but it sure ain't fun no more!
EDIT: I also have to check my trombone, which I hate doing, but I never know when they're going to give me shit for trying to put it in the overhead bin. They made me check it once in the soft case and then lost it for a few days. When I finally got it back the horn was demolished. That's about as pissed off as I've ever been in my life. The good thing was that horn was not a great one and I didn't mind so much losing it- what pissed me off was their "tough shit for you" attitude. Now I put the horn (in the gig bag) into a hard golf case (it fits quite well) and check that. It's always a risk, but I've had no problems yet.
Two things that are a little better; the check-in and security screening seem to be faster in general, and I think they've gotten better about keeping track of luggage.
