If I were you, I'd just go to JFK, although places to spot there are supposedly limited. How far south and west do you want to go? MIA is a great place for spotting, and DFW and DAL have an excellent spotting areas...At DFW there is actually a small park set aside for spotting that provides excellent view of aircraft taking off, taxiing, and landing. At DAL the top of the parking garages are excellent for spotting and no one seems to care.
