What Time Does TSA Open at Every US Airport

Planning your next trip? Here’s the quick answer: TSA checkpoints typically open 2 hours before the first flight of the day, which at most major airports means around 4:00-4:30 AM.

However, timing varies by airport:

• Large hubs (ATL, LAX, ORD): Usually open by 4:00 AM
• Mid-size airports: Often 4:30-5:00 AM
• Regional airports: May not open until 5:30-6:00 AM

For the most accurate information, check your specific airport’s website or call their information line the day before your flight.

Pro Tips for Early Flights

If you’re catching a 6 AM departure, arrive when TSA opens. Lines are typically shortest in the first 30 minutes, before the rush begins. TSA PreCheck lanes may have limited hours at smaller airports, so verify availability.

Most airports post their TSA hours on their official websites under “Security” or “Travel Information” sections.
