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.
As always, it will be essential for travelers to arrive at the airport a minimum of two hours for domestic and three hours for international flights to allow time to get through heavy traffic, park, check in, get through security and navigate to gates. If you're checking bags, add some extra time on top.
