I know that everyone has extra room in their carry ons for information like this. I was doing some looking and found the terms of carriage for the two airlines I travel most often. I'm going to print them and carry them with me. I know that the airline staff is supposed to provide them if requested, but the last time I asked for a copy from United when I was trying to clear up a problem I was told I could get a copy...but I'd have to stay over night while they located them for me! That's service!

Anyway, here are US and UA respectively:

p.s. they also come in handy when trying to overcome insomnia in a hotel room.
