Scenes of airport security lines spilling out of terminals may be adding a new layer of stress for travelers as the busy spring break season unfolds.

Some airports have seen wait times stretch well past an hour. In recent days, passengers reported waiting up to two hours in line at Atlanta’s Hartsfield-Jackson International Airport, while people were advised to get to the airports in New Orleans and Austin, Texas, as much as three hours before their flights.

Many other airports reported wait times in line with normal conditions, making it difficult for travelers — especially those with upcoming trips or those accustomed to arriving at the last minute — to know what to expect.

The uneven delays are being driven by a mix of factors, including a partial government shutdown that has strained Transportation Security Administration staffing, along with heavy spring break crowds. The result is a patchwork of conditions that can shift quickly, even within the same airport.

That unpredictability makes checking TSA wait times before a scheduled departure a key step for airline customers right now.

How to track wait times

TSA is not actively managing its sites during the shutdown, meaning the wait times listed on the MyTSA mobile app may not be accurate. Experts say the estimated wait times listed on third-party websites tracking TSA lines may also be outdated during the shutdown if they rely on publicly available data.

“Luckily, major airports tend to list those checkpoint times, terminal by terminal. I can’t think of a major one that doesn’t,” said Eric Rosen, director of travel content for The Points Guy, a travel and finance advice website.

The most reliable way to monitor wait times right now is by checking an airport’s websites and social media accounts, Rosen said, including the social platform X, where many airports have been sharing timely updates and guidance.

Still, travelers should keep in mind that airport conditions can change quickly, meaning any information might not reflect what is happening at a specific time.

Check early and often

Experts say it’s best to check airport conditions early and often. Waiting until a few hours before a flight can leave little to no margin for delays — for example, if the drive to the airport takes 45 minutes for a flight leaving in three hours.

The shutdown, which began Feb. 14, affects only the Department of Homeland Security, which includes TSA. It is the third funding lapse in a year that has left roughly 50,000 TSA agents working without pay and waiting for money from missed paychecks.
