A growing number of air traffic controllers across the United States are calling in sick, citing the financial strain of working without pay during the ongoing government shutdown. This “sick-out” is creating ripple effects throughout the aviation system, with flight delays and cancellations mounting at airports nationwide.
Nationwide Flight Disruptions
The Federal Aviation Administration (FAA) has issued warnings about staffing shortages at air traffic control facilities across the country. These shortages are directly impacting flight operations, with travelers experiencing significant delays and some flights being outright canceled.
One of the hardest-hit locations has been Nashville International Airport, where the air traffic control tower was operating with extremely limited staffing. This forced some approach traffic to be handled by the air traffic control center in Memphis, Tennessee. Flights in and out of Nashville faced average delays exceeding two hours.

Other major airports experiencing disruptions include:
- Dallas – Average delays around 30 minutes
- Chicago – Average delays around 40 minutes
- Burbank, California – Tower closed for several hours due to zero controllers on duty
- Denver – Over 600 flights delayed on Monday
- Phoenix – Over 200 flights delayed on Monday
In Burbank, the situation became extreme when no air traffic controllers reported for duty at the tower for several hours. While the airport remained technically open, flights were delayed on average by more than 2.5 hours. During this period, controllers from a San Diego facility handled traffic into and out of Burbank remotely.

Understanding the Crisis
Essential Workers in an Unusual Position
Air traffic controllers are classified as essential workers during government shutdowns, meaning they are required to continue performing their duties even though they aren’t receiving paychecks. According to the Department of Transportation’s shutdown plan, approximately 13,294 controllers are continuing to work without pay during this shutdown.
“It is normal for a few air traffic controllers to call in sick on any given day, and this is the latest example of how fragile our aviation system is in the midst of a national shortage of these critical safety professionals,” stated the National Air Traffic Controllers Association (NATCA) in a recent statement.
Nick Daniels, president of NATCA, acknowledged that staffing shortages are not necessarily a new problem, but they’re drawing more attention now because of the shutdown spotlight. “We’re hyper-focused on it,” he explained. “It’s a shutdown. You’re finally seeing the issues of a critically staffed air traffic control system.”
Long-standing Challenges
In fact, Daniels pointed out that in the last nine months alone, there have been 1,058 occurrences where air traffic control facilities had to shut down, either temporarily for a few hours or for an entire shift. While ATC staffing deficiencies exist across the country, it’s relatively rare for these issues to have direct impacts on flights in areas like Arizona or California under normal circumstances.
Human and Economic Costs
Concerns for Controller Well-being
Transportation Secretary Sean Duffy expressed concern about the financial pressures facing air traffic controllers during the shutdown. At a press conference, he acknowledged that staffing levels at certain facilities are down as much as 50 percent.
“We don’t have one facility that has had long-term issues with the sick leave. But that is concerning to me,” Duffy said. “And if someone has to take sick leave, to drive Uber to make the difference, those are decisions they’re going to make themselves. But of course, that’s concerning for us.”
He continued, emphasizing the specialized nature of the work: “These are high-skilled, high-performing, safety-driven professionals that I don’t want them driving for work. I don’t want them finding a second job to pay the bills. I want them to get paid for the work they’re doing today, keeping our planes in the air and our skies safe.”
Duffy highlighted that controllers will receive a partial paycheck on October 14, but if the shutdown continues, they won’t be paid again until October 28. According to NATCA, under the Government Employee Fair Treatment Act of 2019 (GEFTA), controllers will receive back pay after the shutdown ends.
Broader Economic Impact
While exact figures for the economic impact of these current delays are still emerging, past incidents provide some insight. Flight cancellations alone cost American commercial airlines an estimated $22 billion annually. With multiple airports affected and thousands of flights delayed or canceled, the current shutdown is likely contributing significantly to these losses.
The economic impact isn’t limited to airlines. Travelers face direct costs from missed connections, hotel rebookings, and meal expenses. Businesses that rely on timely delivery of goods or employee travel are also affected. Tourism destinations dependent on air travel see decreased visitor numbers, especially when flights become unreliable.
Potential Disruption of Rural Air Service
Another aspect of air travel threatened by the shutdown is the Essential Air Service (EAS) program. This federally funded initiative provides subsidies to airlines serving rural communities that might otherwise lose commercial air service due to insufficient passenger demand. Duffy announced that the EAS program will run out of funding on October 12, 2025.
“Air carriers that continue to operate EAS flights beyond October 12, 2025, would do so at their own risk as the Department may not be able to pay the contracted subsidy,” the Department of Transportation stated in a notice.
Alaska Senator Lisa Murkowski emphasized the critical importance of the program to her state, where air travel is often the primary mode of transportation: “The critical assistance these routes provide makes a disruption on any scale detrimental to these communities, and the local air carriers serving them.”
Historical Context and Precedents
This isn’t the first time government shutdowns have affected air traffic control operations. During the 35-day shutdown from December 2018 to January 2019, air traffic controllers also began calling in sick at increased rates. This pressure was cited as one factor that ultimately helped bring the shutdown to an end.
Reports indicate that even prior to this shutdown, staffing challenges existed throughout the air traffic control system. A CBS analysis of FAA data in January 2025 found that only 10% of U.S. towers were sufficiently staffed to meet FAA standards under normal operating conditions.
Political Implications
The staffing crisis has triggered heated political exchanges. California Governor Gavin Newsom posted on social media, stating, “Thanks, @realDonaldTrump! Burbank Airport has ZERO air traffic controllers from 4:15pm to 10pm today because of YOUR government shutdown.”
Transportation Secretary Duffy responded sharply: “News Flash! Your Democrat friends shut down the government because they want to make Americans pay the health care for illegals. And no state has more illegals than California! You care more about illegals than our hard-working American air traffic controllers. If you’re looking for someone to blame, look in the mirror — we all know it’s your favorite thing to do.”
Conclusion
The current government shutdown has brought to light the vulnerabilities inherent in requiring essential workers to perform their duties without guaranteed compensation. As air traffic controllers continue to face the difficult choice between their civic duty and their financial responsibilities, the traveling public experiences the very real impacts of political gridlock.
With the Essential Air Service program poised to lose funding and controllers uncertain about their next paychecks, the pressure continues to mount on lawmakers to resolve the budget impasse. The situation also raises larger questions about how the nation supports and compensates its essential workforce during government funding gaps.
Whether this latest episode will influence future approaches to government shutdowns remains to be seen, but for now, travelers across the country are experiencing firsthand how political disagreements in Washington can cascade into real-world problems at airports from coast to coast.
