If your goals are to make good use of your expiring SWUs and earn LPs towards status next year, might I suggest JFK-LAX-JFK. Add a night or two in LAX with a BookAAhotels hotel room with both mileage boosts and you'll end up earning considerably more LPs for a lower out of pocket cost. You can book a J fare and upgrade to F if you want to experience FFD on both ends and still might come out ahead vs JFK-DOH-JFK.
