I am flying from Seattle to JFK with Delta. In twi hours time I take a virgin flight to London Heathrow from terminal 4. Can anyone guide me as to how to get going. Will appreciate as gave not been to JFK before. Thanks.

If you want to get Delta you need to go by Airtrain to delta Terminal. Find Airtrain and ask about Delta. And Airtrain is an automatic train it will be calling for any terminal before you approach so that you come to exit gate. Take care of yourself have a very good day. I have very good experience of the Airport Regards Shoaib #Pakistan.

Do what the others have said .

If you land at Terminal 2, there are shuttle buses to take you to Terminal 4. Check your flight as Delta often lands at Terminal 4
