Just did that recently. Flight was in terminal 1, lounge is in terminal 3. Only way to/from is through security at each terminal and the inter-terminal train. Not too bad if you have pre-check and the time...
No, have to go to Terminal 3 or the international terminal. Pain in the butt to go through security again, but necessary if you want to visit
You will need to go through security at term 3. Then back through 2 to get to your gate.
Yes you can just walk there now, no need for re checking in security. The walkway was opened end of 2021.
You have to use AirTrain - also please note they will only give Platinum members access 3 hours prior to their flight, unless it is a transfer.
Keep in mind there are no exceptions from mechanical front desk staff to ridiculous three/3 hour policy when your flight leaves from another terminal and you need to reclear security.
i guess folks answered your question
