At least by 630 it's not hard to get checked in and go through security at BTR
620 am. Security is quick.
On average for flights within the US - 1 hour before boarding and for international its 2 hours. Depending on the day and time of travel as well as if you have luggage to check, rental cars to drop off or if you require extra time, you want to givr your self some additional time especially if its a heavy travel time of year.
