I don't believe that "JFK is the odd one out". While I'm not privy to AA strategic planning, it does seem that as the largest airline in the world, AA can effectively support two northeast international hubs better than anyone else. PHL vs. JFK is not a zero sum game. I don't use JFK often, but the few times I've flown in and out this year it has appeared as though AA is utilizing every gate. Personally, I wouldn't mind a few less International flights out of JFK in exchange for for connections to non-hub cities like STL or SAN. Either way I don't see any sign that JFK is being deprecated. UA on the other hand has retrenched into its EWR fortress and truly has deprecated LGA after abandoning JFK. I think AA is still bullish on NYC.
