Hello, we recently booked two tickets on AA from MCI to Washington DC. When you login on aa.com and try to select your seats there are no seats available without the up charge. It looks like it's a very small plane and the only seats to pick on their are $52.00 and look like first class in the first few rows. We already paid for standard airfare and seats during booking since it showed it was available. My question is what will happen if we don't select any seats and just wait until we check-in? Will we be charged more for better seats? Will we most likely get assigned those extra nicer seats for no charge? Or something much much worse and they are out of room?
