Long TSA lines this summer. The TSA is expecting long lines at their security check points during the busy summer travel season â especially when youâre traveling in the morning. The TSA recommends arriving at the airport at least 2 hours early for domestic travel and 3 hours early for international travel.
If you feel you need to, please allow yourself extra time to get to the airport and to get from the entrance of the airport to your particular departure gate. United recommends that passengers arrive at the airport an hour prior to all flights within the U.S. and two hours prior to all international flights.
