Usually 2 hours before fly estimate time
I personally like getting there 2 hrs before my flt. Parking, security at times cause some delays...so to relieve the stress factor better to get there early than have increased stress.
Faa says 2 hours
The most important thing to remember is that the time on your ticket is the time your plane needs to be IN THE AIR. Boarding typically begins 30-45 minutes before that time. I would recommend getting to the airport and hour and a half before your flight. Just in case there are parking, check-in, TSA, or gate problems.
I usually arrive 1 hr in advance, security check doesn't take much time. But it depends on rush hour. You can also check with your airline
