Arrived in the BVI again last night. Daughter opted to take her family of 5 on the new MIA flight. Connecting flight into MIA ran late but they made the flight and were relieved to see the checked bags show up at the flight with 10 minutes to departure. Sadly the flight pushed 8 minutes early and they left all their bags. I suspect maybe a landing weight issue. I told my daughter not to worry as AA would put them on the SJU flight and connect them over to the BVI. I was wrong and the bags are still in MIA and no one at AA will even discuss it. Just wait 5 days and file a claim. Suggestions? AA agents at Beef Island would not even give her the 13 character code to track lost bags and impossible to get someone on phone.
