How the Shutdown Affects Airport Operations

A government shutdown reduces staffing at airports across the country because the Transportation Security Administration (TSA), air traffic controllers, and airport maintenance workers are federal employees who stop receiving paychecks. TSA officers may call in sick at higher rates, creating longer security lines. Air traffic control towers operate with minimal staff, which can slow down takeoffs and landings. Airports themselves stay open, but the reduced federal workforce creates bottlenecks that ripple through flight schedules.

Not all airports are affected equally. Major hubs with high traffic and older infrastructure feel the impact faster than smaller regional airports. An airport with one security checkpoint and 20 daily flights can absorb staff shortages better than one with six checkpoints and 500 daily flights. The length of the shutdown matters too—delays worsen after the first few days as fatigue sets in and maintenance backlogs grow.

Key Takeaways

  • The busiest airports—Atlanta, Dallas, Los Angeles, Chicago, and New York area airports—typically experience the longest delays because they have the most TSA officers and air traffic controllers to lose.
  • TSA wait times usually spike after the first three to five days of a shutdown as officers work without pay and call in sick at higher rates.
  • Regional airports with fewer flights and security checkpoints may see little disruption, while major hubs can experience hour-long security lines and flight delays of 30 minutes to two hours.
  • Air traffic control delays happen at busy airports even when security lines move quickly, because controllers are working with reduced staff and cannot clear planes for takeoff as fast.

Major Hubs Hit Hardest by Staffing Shortages

Hartsfield-Jackson Atlanta International Airport (ATL), the world's busiest by passenger count, typically experiences severe delays during a shutdown. The airport processes over 2,500 flights per day and relies on roughly 1,000 TSA officers. When staffing drops by 10 to 15 percent, security lines back up into the terminal corridors, and some passengers miss flights. Air traffic control delays compound the problem because Atlanta's tower handles traffic for one of the busiest airspace regions in the country.

Dallas/Fort Worth International Airport (DFW) and Los Angeles International Airport (LAX) face similar pressures. DFW handles about 1,800 flights daily with roughly 800 TSA officers. LAX processes about 1,400 flights daily with similar staffing. Both airports have reported security wait times exceeding 90 minutes during past shutdowns, even though the airports themselves remain open and flights continue to operate.

Chicago O'Hare International Airport (ORD) and the New York area airports—John F. Kennedy (JFK), Newark Liberty (EWR), and LaGuardia (LGA)—also experience significant delays. These airports handle 1,200 to 1,500 flights per day each. The New York area is particularly vulnerable because three major airports share the same airspace and air traffic control system, so staffing shortages at one facility affect all three.

Regional Airports and Secondary Hubs

Smaller regional airports—those handling 200 to 500 flights per day—typically see minimal disruption during a shutdown. Airports like Austin (AUS), San Diego (SAN), and Nashville (BNA) have fewer TSA checkpoints and air traffic control complexity. A 10 percent staffing reduction at a small airport might mean one extra person in line at security, not a 45-minute wait. These airports can usually absorb the loss without major delays.

Secondary hubs like Denver (DEN), Phoenix (PHX), and Miami (MIA) fall in the middle. They handle 800 to 1,200 flights daily and experience moderate delays—typically 15 to 45 minutes—rather than the severe delays seen at the largest airports. The impact depends on how long the shutdown lasts and how quickly staff fatigue accumulates.

When Delays Get Worse: The Timeline

The first 24 to 48 hours of a shutdown often show minimal delays because most TSA officers and air traffic controllers report to work anyway, expecting the shutdown to end quickly. After three to five days, delays spike noticeably. Officers working without pay begin calling in sick at rates two to three times higher than normal. Air traffic controllers, who are also working without pay, experience fatigue and stress that slows their ability to clear planes.

By the second week, delays at major airports can reach two hours or more for security screening alone, plus additional delays from air traffic control. Maintenance work on runways, taxiways, and ground equipment also falls behind, which can force temporary closures of runways or taxiways. This creates a cascading effect: fewer runways available means fewer planes can take off, which backs up the entire system.

Checking Real-Time Delays at Your Airport

The Federal Aviation Administration (FAA) website at faa.gov displays real-time delay information for major airports. You can search by airport code and see current delays, the reason for delays, and expected wait times. The TSA website at tsa.gov also publishes current wait times at major airports, updated throughout the day. Individual airlines post delay information on their websites and apps as well.

During a shutdown, check these sources before heading to the airport. A delay listed as "weather" or "traffic" might actually include shutdown-related staffing shortages. If you see delays of 30 minutes or more at your airport, arrive at least two hours early for a domestic flight and three hours for an international flight. If delays exceed 90 minutes, consider rescheduling if your travel is flexible.

What Happens to Flights During a Shutdown

Flights do not stop during a shutdown—the FAA continues operating because air traffic control is considered essential. However, the reduced workforce means fewer planes can be in the air at once, and planes spend more time waiting on the ground for clearance to take off. A flight that normally takes 45 minutes from pushback to takeoff might take 90 minutes.

Airlines may cancel flights at busy airports to reduce congestion, which can free up gates and reduce the total number of planes waiting. This is a deliberate strategy to keep the system from becoming completely gridlocked. If your flight is cancelled, the airline will rebook you on the next available flight, which may be hours or days later depending on how full subsequent flights are.

Frequently Asked Questions

Will my flight be cancelled if there is a shutdown?

Most flights operate during a shutdown, but delays are common at major airports. Airlines may cancel some flights at busy hubs to reduce congestion. Check your airline's website or call them directly to confirm your flight status. Cancellations are more likely on the second week of a shutdown than the first few days.

Which airports have the shortest delays during a shutdown?

Regional airports with fewer than 500 flights per day—such as Austin, San Diego, and Nashville—typically experience minimal delays. Airports in less congested airspace, away from major metropolitan areas, are also less affected. Check the FAA website for real-time delays at your specific airport.

Do I need to arrive earlier than usual if there is a shutdown?

Yes. Arrive at least two hours early for domestic flights and three hours for international flights at major airports. At regional airports with short delays, standard arrival times may be sufficient. Check TSA wait times on tsa.gov before you leave home to decide how early to arrive.

How long do shutdown delays usually last?

Delays worsen as a shutdown continues. The first few days may show minimal impact, but by day five to seven, delays at major airports can reach one to two hours. Delays persist until the shutdown ends and staff return to normal levels, which can take a day or two after funding resumes.

Can I get a refund if my flight is delayed by a shutdown?

Airlines are not required to refund tickets for delays caused by a government shutdown, because the shutdown is considered an external event beyond the airline's control. You may be able to rebook on a different flight at no charge. Check your airline's policy or contact them directly about your options.
