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.
How early should I arrive to the airport prior to my flights departure? You are encouraged to arrive at the airport two hours prior to flight departure for domestic travel and three hours for international travel. This allows time for parking and shuttle transportation, airline check-in, obtaining a boarding pass, and going through the security screening process, which includes screening of your carry-on baggage.
