Airlines Cracking Down On Big Carry-On Bags

Airlines are cracking down on passengers who try to cram big carry-on bags into the overhead compartments.

Some airlines are charging for checked luggage to cover rising costs of jet fuel. Now, they say it's only fair to fee-paying customers to keep others from trying to sneak bulky bags onto planes.

If a passenger is stopped with an oversize carry-on, American says it will charge that person a $15.00 fee to check the bag at the gate.

United says it hasn't decided how to handle the situation. U.S. Airways says its passengers can check those bags for free at the gate.
