American Airlines announced today that as of the 15th of June they will begin charging for the 1st piece of luggage. The charge is $15 for the first piece. Delta has already said that they will not be charging.
Interesting question... when they are charging you for the service, should the liability be higher? Shouldn't you get a refund of the service charge as well as a higher liability when they lose your luggage?
For the moment, unless AA is $15 cheaper for a flight... I suggest booking with another airline. It's hard enough to fly and having to check luggage so you can bring toothpaste with you, but now it's $15 to take a tube of toothpaste in the hold.
