5am at the latest. Security doesn't take long at this small airport.
No, you can arrive a bit later... 4:30am should be early enough. It's only when there are also Allegiant flights that you should leave that much extra time...
TSA opens at roughly 430am. You will want to ensure that you arrive with enough time to check in get through security and to the gate before the boarding process begins. I believe most airlines begin boarding 30 to 45 minutes before the scheduled departure time. I hope that is helpful.
