I called AA at 1-800-433-7300 twice. First over a month ago and then today. I called to check on my seats and then I asked again about luggage situation. And she confirmed that we can take two pieces of 50 Lbs and a carry on for 40 Lbs. One of the pieces can be the scuba gear but no tanks allowed. This is an international flight and the charges for the bags do not apply. Thatls all I know. I hope we will not have problems on Miami. See at the gate!!
