American Airlines will be massivley upgrading thier JFK and MIA hubs, and international flights will, without a doubt, be a key part of thier expansion (MIA will grow from 192 to 330 daily flights with the new Super Concourse). I would not be surprise to see some routes transfered. Miami could defintley use flights LIS, FCO (Alitalia will be dropping twice weekly FCO/thrice weekly MXP service with daily MIA-MXP-FCO-MXP-MIA service), and ATH. MIA-MAD is a very popular route and one that AA might want to add a second daily on. MIA-BCN is one of the key routes that Miami does not have non-stop (currently one-stop on IB). The possibilites are endless at JFK as well.
