For once we have actually managed to get to an airport well ahead of time we were there 1.5 hours before our flight leaves! A miracle for us!
After returning the car, we took the air train, which is in walking distance from Hertz car rental. Delta flies from terminal 2, we got off at terminal 2 from there it is about 5 – 7 minutes walk to the check in desk.
We visited the delta lounge which was nice, our priority pass did not allow us entry but they allow access for American Express platinum charge card holders.
