Eh, I think the key to happiness in airline travel (and really, in life) is to have realistic expectations. If you have unrealistic expectations, then life is going to kick your ass all over the place.

When I fly I expect delay, inconvenience, uncomfortable seats, lost luggage, etc. If those things don't happen, I'm pleasantly surprised but if they do it doesn't ruin my day.

Since I don't have to travel for work a lost bag or a delayed flight doesn't have a huge impact on me so I guess I can afford to be more cavalier about the whole thing.
