There is a place you can sit in the baggage claim area 24 hours a day
Go as early as you like. It is open 24 hours.
24 hours open
I had a flight at 6 AM and the TSA line didn't open up until 4 AM. I'm not sure if that is a common practice or this was just a one time event. Haven't had another early flight like this since then.
It's advised to get to the airport 2 hours before your flight
