none of which are in the southeast.
DTW does have nonstop flights to GRU, BTW.
so does that mean that you will be flying AA equipment and vice versa...?
since the majority of traffic even on AA's flights from MIA to S. America are connections, the value of the O&D is not the issue. CLT has very low amounts of local O&D which means that CLT provides network competition to MIA. AA needs to funnel as much traffic as possible thru MIA because AA's ability to dominate Latin America is dependent on retaining its dominance over MIA.
AA cannot afford to siphon traffic off of MIA just as competition from S. Florida to Latin America heats up.
The DL GRU frequencies that DL gave US as part of the LGA-DCA slot deal were specific to CLT, IIRC.
I'd like to see the legal paperwork to confirm but since the Brazil awards are gateway specific, the chances are high that AA lost those frequencies with its decision to cancel CLT-GRU service.
Since AA had to add Campinas (VCP) service with frequencies it already had to GRU (GRU and VCP are considered a single point for bilateral purposes), the evidence seems to be that AA lost the CLT frequencies.
forget about JFK
