Also, Southwest's no-questions-asked-no-limits policy on cancelling and rebooking tickets makes them my favorite. They recently put a limit of one year on the rebooked ticket, however. You can do this right up until boarding has already begun and there are no penalties. Nobody else does this. They're polite, they're generally well run, seats are reasonable, maintenance seems to be good, they have good routes, cheap tickets, good baggage policy, and don't fee you to death. On top of that, they have responsive customer service on the phone, or via DM Twitter, which is way better than sitting on the phone! Whatever they're doing is the right way and all other airlines should just copy them.
