I'm reasonably happy while on the plane. I don't need that much space. I'm happy in either aisle or window. I don't expect food in the plane, so I've taken care of my hunger before boarding. I rarely drink much, as I always have to drive at the end of my flight. I bring on my own book/movie/music/work project, so IFE is unimportant to me, as are the FA's and surrounding passengers (I'm in my own little world). Most of my flights are for projects/jobs that last 3 days to 2 weeks and involve equipment, so I always have checked luggage and I'm not so concerned with rushing on/off or being as close to the front as possible. I'm basically easy to please on a plane.

Off the plane, however, is another story. I hate the whole TSA dance, strongly dislike most airport layouts, abhor the rude people at the baggage carousel who won't let me get to my bags, resent paying a fortune for a snack at the airport shops, wish most airlines had better reservations systems, wish airports had lockers in this post-9/11 world, and wish most airports were located closer to the city or in nicer parts.

Oh, and I'd like to pay a lot less for my travel.

Other than that, I like airline travel just fine.
