Where TSA wait times are the longest, and how to check if your airport is impacted

• Delays persist at TSA checkpoints across US airports due to the partial government shutdown.
• TSA agents aren't getting paid during the shutdown, and as many as 10% aren't showing up to work.
• Here's the latest on TSA delays, and how to check wait times before you travel.

If you're flying in the US, get ready to stand in line.

Airports across the US are continuing to see lengthy waits at security checkpoints as scores of TSA workers call out due to missed paychecks.

A partial government shutdown has left the Department of Homeland Security and its Transportation Security Administration unfunded and their agents unpaid at the height of the spring break travel season.

As many as 10% of all TSA agents called out on several days this week, DHS updates showed, with absence rates averaging as much as 20% in some airports.

Security lines in affected airports are spiking unpredictably from day to day, and sometimes even from hour to hour.

"The current unpredictability is being driven by unpredictable staffing levels, basically, how many TSA officers are showing up for work on any given day," Sheldon H. Jacobson, the founder professor of engineering at the University of Illinois Urbana-Champaign and an expert on airport security screening, told Business Insider.

"TSA officers have historically been cross-trained to do many different tasks, so the number that show up is the key factor," Jacobson said.

How long are the TSA delays?

Delays at TSA checkpoints across the US have been unpredictable in recent days, with some airports hit much harder and wait times varying massively from day to day.

On Thursday, among major airports, delays appeared to be worst at Houston George Bush International Airport, where lines at some checkpoints exceeded 2 hours.

Long lines continue.
If you're coming to the airport, give yourself time. Wait times fluctuate throughout the day.
Thank you for your patience.

Hartsfield-Jackson Atlanta International Airport, the world's busiest by passenger numbers, has been among the worst-affected, with delays of over 90 minutes on most days this week. By late morning on Thursday, however, the longest wait at the airport was 7 minutes.

In a Wednesday X post, the airport encouraged travelers to allow extra time for screening and to arrive at least 3 hours before their flight.

In an X post on Tuesday, the airport said there was congestion at the international checkpoint due to domestic travelers trying to bypass long lines in the domestic terminal. The airport said domestic travelers should use the domestic checkpoints.

Lines at checkpoints in three terminals at JFK, the New York area's biggest airport, were over 15 minutes, while waits at Newark were similar. At LaGuardia, the wait was around 20 minutes at worst.

During the morning travel rush, waits at Dallas-Fort Worth were over 25 minutes, but by late morning, the longest wait was under 15 minutes.

At Denver, the US's 4th-busiest airport, lines were over 35 minutes soon after the airport opened, according to its website, but soon dropped to 20 minutes or less.

In Philadelphia, lines stretched down escalators in the terminal building, as video shared by one local news reporter showed.

Some airports have so far avoided the hourslong queues. Business Insider's Taylor Rains flew out of Las Vegas on Monday and saw minimal TSA lines.

However, the unpredictable nature of the delays means travelers should plan for long waits even if their airport hasn't yet experienced problems. Airports like Denver and Seattle have asked the public for food, gift cards, and basic supplies to support TSA staff working without pay.

How to check TSA wait times

The easiest way to avoid the stress of missing your flight is to give yourself extra time in the airport. Many airports are advising travelers this week to arrive up to three hours before their flight, even for domestic flights.

Many airports, including major hubs like Atlanta, Houston, JFK, Newark, Philadelphia, Dallas-Fort Worth, and Denver, have been posting TSA wait times live on their websites.

These can also provide more specific insights. For example, DFW's website shows the wait times at each checkpoint.

You can also use the MyTSA mobile app. It provides estimated wait times in 15-minute intervals based on average checkpoint data. The app, however, will use historical data if the live data cannot be retrieved. The TSA also says it is not "actively" managing its sites during the partial shutdown, and so the app may not always be updated.

How long will the TSA delays persist?

On Thursday, Transportation Secretary Sean Duffy said airport delays could get even worse.

"As we get into next week and they're about to miss another payment, this is going to look like child's play, what's happening right now," Duffy said on CNBC.

Some airports could even be forced to shut, both Duffy and Adam Stahl, the TSA's acting deputy administrator, said.
