This March I'll be passing through JFK on my way back home from vacation. I will be arriving at 5:30 PM and leaving at around 6:30 PM. I will be flying on Delta so I'll be stuck in terminal 3. What are some places in Terminal 3 that I can get some decent shots of the A/C in Terminals 2 and 4? I only have about half an hour between flights so I can't leave the terminal. What airlines use the gates in 2 and 4 that you can see from 3? Also, what runway is usually in use for that time of day and is there going to be a lot of international traffic?
