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.
Arrive Early! Travelers are encouraged to arrive a minimum of two hours before domestic and three hours for international flights â give yourself time to park, check-in and get through security. Additionally, if youâre checking bags, add some extra time on top of it. Itâs always better to be early.
