US Airport Security Lines: What to Expect During DHS Shutdown (2026)

The specter of a U.S. Department of Homeland Security shutdown looms, threatening to unravel the smooth flow of air travel and leaving passengers on edge! Many travelers might be having flashbacks to the 43-day government shutdown last year, which brought about a cascade of flight cancellations and agonizingly long queues at airports. This time, the agency tasked with the critical job of screening everyone and everything – the Transportation Security Administration (TSA) – is at the heart of the funding dispute.

Here's the kicker: TSA officers are expected to continue their vital work without receiving a paycheck while lawmakers remain deadlocked on the Homeland Security's annual budget. While TSA agents heroically worked through the record-breaking shutdown that concluded on November 12th, aviation experts suggest this current situation could unfold differently. The longer the Department of Homeland Security's appropriations remain in limbo, the greater the potential for extended security lines at our nation's commercial airports, according to leading U.S. travel industry trade groups and major airlines.

So, what's the lowdown on this latest shutdown and how can you navigate it like a pro?

What's Different This Time Around?

Funding for Homeland Security officially lapsed at midnight. However, the rest of the federal government is funded through September 30th. This is a crucial distinction because it means air traffic controllers, employed by the Federal Aviation Administration (FAA), will continue to receive their salaries as usual. This significantly reduces the likelihood of widespread flight cancellations that can cripple travel plans.

According to the department's own contingency plans, a staggering 95% of TSA workers are classified as essential personnel. This means they are legally obligated to keep working, even without pay. On the political front, Democrats in both the House and Senate have stated they will not approve funding for Homeland Security until new restrictions are implemented on federal immigration operations. This is a point of contention that could prolong the shutdown.

And this is the part most people miss: In past shutdowns, disruptions to air travel typically didn't manifest immediately; they tended to build gradually over time. For instance, about a month into the previous shutdown, the TSA had to temporarily close two security checkpoints at Philadelphia International Airport. On that very same day, the government took the extraordinary measure of ordering all commercial airlines to scale back their domestic flight schedules. This time, however, John Rose, chief risk officer for global travel management company Altour, believes that strains could surface at airports much more quickly. Why? Because the TSA workforce has the memory of the last shutdown fresh in their minds, and potentially, their wallets.

What Does This Mean for You, the Traveler?

Predicting exactly when or where security screening hiccups might occur is a tough call. Even a small number of unscheduled absences among TSA officers could rapidly lead to longer wait times, especially at smaller airports where there might be only one security checkpoint. This is precisely why the golden rule remains: always plan to arrive early and allocate extra time for security. As Rose wisely puts it, "I tell people to do this even in good times."

Experts also caution that flight delays are still a possibility, even though air traffic controllers are not directly impacted by this DHS shutdown. Airlines might, in some instances, choose to delay departures to allow passengers more time to clear security screening, according to Rich Davis, senior security advisor at risk mitigation company International SOS. Furthermore, shortages of TSA officers could also slow down the screening of checked luggage behind the scenes, adding another layer of potential delay.

Your Preparation Playbook: How to Stay Ahead of the Curve

Most airports provide real-time security line wait times on their websites. However, don't wait until the day of your flight to check them! As Rose points out, "You may look online and it says two-and-a-half hours. Now it's two-and-a-half hours before your flight and you haven’t left for the airport yet." It's crucial to check these wait times well in advance.

When packing, pay meticulous attention to what you're bringing. Prohibited items are a surefire way to prolong the screening process for everyone. For your carry-on bags, steer clear of full-size shampoos or other liquids, large gels or aerosols, and items like pocketknives. The TSA offers a comprehensive list of what's permitted and what's not for both carry-on and checked luggage on its website.

Once you're at the airport, remember the mantra: "practice patience and empathy." As Rose reminds us, "Not only are they not getting paid, they’re probably working with reduced staff and dealing with angry travelers."

Will This Shutdown Drag On Indefinitely?

The White House has been engaged in negotiations with Democratic lawmakers, but a breakthrough deal eluded them before senators and members of Congress were slated to depart for a 10-day recess. Both chambers have been put on notice, however, to return to Washington if an agreement to end the shutdown is reached.

Democrats have firmly stated their position: they will not consent to further funding for Homeland Security until new restrictions are imposed on federal immigration operations. This stance has been amplified following the tragic shootings of Alex Pretti and Renee Good in Minneapolis last month.

But here's where it gets controversial: The U.S. Travel Association, Airlines for America, and the American Hotel & Lodging Association have issued a joint warning that the shutdown poses a significant threat to air travel, especially with the busy spring break season on the horizon. Their statement powerfully articulates the concern: "Travelers and the U.S. economy cannot afford to have essential TSA personnel working without pay, which increases the risk of unscheduled absences and call outs, and ultimately can lead to higher wait times and missed or delayed flights."

What are your thoughts on essential workers being forced to work without pay during government shutdowns? Do you believe the political deadlock is justified given the circumstances? Share your opinions in the comments below!
