Surcharges Galore

With gas prices soaring, it's not surprising that prices for air transportation are exponentially being hiked up but charging for a single piece of checked luggage? And charging extra for unaccompanied minors?! Plain strange. Yep, American Airlines just announced that they are upping charges on both of these items ($15 for your first bag checked, $25 for your second one). One thing is fare increases but I think the second one is absurd; how does an accompanied minor deem a surcharge on the passenger? What will be next?
