It depends on your flight I really think an hour and a half should be sufficient. I was there an hour early for a flight I already had checked in and did not have checked baggage and it took less than 10 minutes to go through security. 2 hours is a maximum time I would think. You are going to wait I'm sure
2 hours early
1 hour and 1/2
Depends on which airline, I work united at we require and hour and a half for regular and two hours for connecting to intl destinations.
1 hour ahead of your scheduled boarding time will give you ample time to check you bag and get through TSA
