No issues flying out Thanksgiving morning at 7:13 AM or on the return at 12:40 AM on Monday. Arrived at Park-n-Fly at 5:15 AM. Shuttle dropped us off at 5:35 AM after picking up some other people. An approx. 10 minute wait to clear security with all of the lanes open. We had enough time before our flight on Thanksgiving Day to walk all three concourses. If you want to find a quiet spot, Concourse A is the place to go. Deplaned at 12:53 AM. After deplaning, we had an approx. 15 minute wait for the Park-n-Fly shuttle. The Park-n-Fly wait was likely due to our late arrival time when only a few flights were coming in. We were in our car and headed home at 1:27 AM.
