It sounds like AA@JFK won't be doing a whole lot more diversifying of its international route network out of JFK anytime soon, especially as AA seems to do anything but expand its domestic feed into JFK for onward international trips and seems to want to send feed elsewhere, particularly PHL.

I wonder if DL thinks of JFK the same way as AA thinks of JFK. DL seems to be much more about a diversified international route network out of JFK than AA, and yet I would say that DL seems to have beat AA in NYC for O&D and that DL has a heavy emphasis on attracting the NYC premium traveler.

If AA's international flying out of JFK hasn't been that much of a useful money-maker for AA, how come DL seems to have found a way to make JFK work for it?
