Just booked flights from MIA-LHR -DEL for 4 of us in F, thinking 1A, 1K and 2A and 2K in he 747? What are your thoughts? I've flown 1A and 1K before but why don't seem to be available to pick at this time, is there a trick or time when they arereleased? Can't remember. BTW, our seats in F were actually $300 less than in J! I'm a happy camper.
