BOS-Small hub. On the LUS side it has the shuttle operation which seems successful. Don't think BOS is going anywhere.

JFK/LGA- The NYC market has enough O/D traffic to support the international flights. They will not pull out of the largest market in the US.

PHL- This one would seem that it would be at risk being so close to LGA/JFK and DCA. PHL is in a good location to be a hub on the east coast and funnel point for trans atlantic traffic. There are not enough slots available in NYC to replace PHL.

DCA- Another big market, with O/D traffic to support it. Doubt it's going anywhere.

CLT- To me, this one seems to be most at risk since it's almost all connecting traffic. However, word on the street is it is VERY profitable. AA has a huge cost advantage in this hub. As long as it remains profitable it should be safe.

MIA- Gateway to Latin America. I've never flown into MIA and don't know much about this hub but I haven't heard of anyone thinking MIA is going anywhere.

ORD- Keeps shrinking. Execs keep saying ORD is vital. Not sure what their long term plan is, maybe they're OK being behind United.

DFW- Fortress

PHX- Execs say it's profitable and isn't going anywhere. Not enough gate space at LAX to absorb the flights. If a hub were to disappear, I think this would be it IF they can secure more gates in LA.

LAX- Growing. AA wants to be number 1 in the LA market. We can't get enough gates.
