From U.S. Airways:

Today, US Airways announced a change to our baggage policy. Beginning May 5, 2008, we’ll charge $25 for a second checked bag. The new fee applies to travel on or after May 5 for tickets purchased on or after February 26, 2008.

I haven’t checked a bag in years — even for long and international trips — because the airlines always find a way to lose them. (When I went to Iowa earlier this year, they took and nearly “lost” my carry-on bag — long story). So if you like to travel heavy, I’m sorry that I won’t be paying for you anymore.
