Bad weather around New York forced some flights to divert from LGA to JFK. Not a bad option if passengers are permitted to deplane. It does create a silly situation of flights from JFK to LGA. There were at least 8 earlier this week. If I were diverted and not in a rush, I'd try to take that flight, just to say I flew from JFK to LaGuardia once. Besides, it's only a 16 minute flight (11 miles direct, 65 miles flown for UA 682).
