I'm currently waiting for my gf to arrive from ORD and just learned that her flight AA342 and at least 2 other flights scheduled to fly ORD-LGA this evening are being diverted to JFK.
AA342 is a MD80
UA694 is a 737-300
UA836 is an A320
Should make for some interesting (rare) shots at JFK as well as ferry flights into LGA tomorrow.
