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.
When traveling to the U.S. from an international city, we suggest that you arrive at least three hours prior to your flightâs scheduled departure time during peak travel periods. Boarding may begin as early as 30 minutes prior to your flightâs departure time. You should be in the gate area with your boarding pass in hand at least 10 minutes prior to departure, or your reservations may be cancelled and you will not be eligible for denied boarding compensation.
