4:30-6:00 can be rather busy. Arrive at least an hour and a half early. You can always get a cup of coffee, or a bite to eat. Restaurant opens at 0500 now!!
Janis I would get there around 5 cause that is around the busiest time for us
I would arrive at the latest 1.5 hours to departure
I would arrive about an hour or so early. That flight has a tendency to be busy, so give yourself some time.
