Please still arrive about 1-1/2-2 hours before flight time. The lines get sort of long about an hour before. The restaurant (JK Flyers) does open about two hours, sometimes three, beforehand and this allows you to get through a line at the ticket counter, get rid of your checked bags with TSA, and enjoy a stress-free environment waiting for security to open and the plane coming to land.
DO NOT think that this is a smaller airport and you can check in 30 minutes ahead of time. The ticket counter does close 45 minutes prior to flight because the same people that work the ticket counter also need to prepare and work with the plane arriving. NOTE: If you have a boarding pass and only a carry-on or personal bag, you can skip the ticket counter and go right to security.
