We arrived at Islip at 4:45 a.m.for a 6:30 flight. It was a rainy morning, and I'd planned to be there at 4:30. We drove and had no problem finding a parking spot. There were about 6-8 people on line ahead of us at the ticket counter, and about the same going through security. We had plenty of time. However, if you are picked out of the line to have your bags searched, that is where you need the extra time. Islip is really a pleasure!
