Arrive Early! Travelers are encouraged to arrive a minimum of two hours before domestic and three hours for international flights—give yourself time to park, check bags and get through security.
Peak hours can mean TSA checkpoint lines are longer. The busiest times typically are between 5–11 am. Increased flights during the evening create another busy period between 7–9 pm.
Thursday and Fridays are the busiest days during the week.
Pack Safe: know before you travel what items are and aren't allowed in carry-ons and checked bags.
Print boarding passes ahead of time or use self-serve kiosks at ticketing.
Travelers can reach all gates from any TSA security checkpoint. The central checkpoint is open 24/7.
Empty liquids before you get into TSA lines.
At security checkpoints, have boarding pass and ID ready and remove laptops from their bags ahead of time.
Sign up for Trusted Traveler programs such as Pre-Check or Global Entry. These programs allow approved travelers to take specific designated lines for quicker service through checkpoints.
