Hi, I'm on a Delta flight to JFK landing at Terminal 3 @ 1214 and connecting to a flight to Heathrow with Virgin Atlantic at Terminal 3 @ 1815. Questions: (1) do I have to collect my luggage from one flight to the other? (2) how do I get from Terminal 3 to 4? (3) how long will it take to get from one terminal to the other? Many thanks!
