I fly pretty often
and I hate it with a passion. I used to fly United between Washington Dulles and Denver pretty frequently. I really hated the DC-10s United used on that route until replaced with 777s. I get the impression that the employees in nearly all areas are overworked with ever-increasing pressure for safety and security. Unfortunately, comfort, convenience, and courtesy seem to have gone the way of the dodo.
Airline security is just the worst. The TSA could learn a valuable lesson from El Al, the Israeli airline. I flew to Israel for 10 days in 2008 and you first go through TSA security, then you go through El Al security. The folks at El Al were nicer, more efficient, and far more thorough. It is the only time since 9-11 that I have gone through any airline security and didn't feel like a piece of meat up for inspection.
More recently, I have started taking the train. Although Amtrak has its problems, I have found my travel experiences on it to be pleasant. I have been delayed on Amtrak, but they always say what the reason is, what is being done about it, and they even give a reasonably accurate estimate of how long the delay will be. The seats are far bigger and more comfortable on Amtrak than the airlines, the food is a lot better (and it's often a decent value too). I like the dining cars with real table cloths and stainless steel flatware (what a concept!).
Flying used to be an experience, now it's a chore. I feel bad for the hard-working folks who watched their industry go from exciting to depressing.
