AMR can easily pass up what it doesn't need or want. how do we know they dont need or want? They have made no attempt to build one since the 80's.Both RDU and BNA both do not have the cost advantage and revenue premium CLT has. MIA is not really set up for domestic southeast connections. AA uses MIA for a Latin America gateway. While CLT may not be what AA is beating down the door for it certainly wouldn't pass up on the opportunity if it came up.
