"Several airlines confirmed Tuesday that they are raising prices on many domestic routes by $10 one way and $20 per round trip...

United, Continental and Delta said they're raising prices effective immediately. Travel website FareCompare.com said American was too, but the airline didn't respond to a request for comment.

Southwest did not immediately go along with the higher prices, which raised the possibility that the other airlines might back down, FareCompare suggested."
