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.
The Transportation Security Administration (TSA) recommends that you arrive at the airport two hours prior to the departure time for domestic and three hours prior to international flights. We encourage passengers to give themselves additional time during peak travel periods and inclement weather.
