My experience with long term parking at JFK.
I didn’t use a GPS, so I followed the signs. There were times I worried that I was lost, but then I’d see another sign pointing to long term parking. It’s passed the cell phone lot.
When we got there, there was plenty of parking. Then we needed to walk all across the lot to the air tran. Waited 2 minutes, and rode for 4. Then walked through terminal 5 to the gates.
