Matthew Yglesias thinks we should stop complaining about air travel. Most of his arguments are right as far as they go but he doesn't address my two big gripes about the airlines. One is the incredible expense and hassle you incur when you need to cancel or change a flight. The other is how when you have a problem, there are very few employees to talk to and most of them don't know anything. I'd agree that when things work, they work pretty well…but they don't always work.
