What time should I arrive before my flight?

At least an hour and a half to account if they are backed up at the security checkpoints. The rest of it is smooth sailing.

Hour and 30 minutes some flights be late or a hang up on boarding the plane

At least 90 minutes

At least an hour if you're not checking any bags

At the busiest of times no more then 90 min is needed

3 hours prior your flight
