On May 21, 2025, Austin-Bergstrom International Airport (AUS) faced one of its most disruptive days in recent memory. The Federal Aviation Administration (FAA) imposed a ground delay program that lasted nearly the entire day, causing widespread flight delays and frustration for travelers. The reason was clear and troubling: a severe shortage of air traffic controllers in the airport’s control tower. This event is not isolated but part of a growing national crisis that is straining the U.S. aviation system and directly impacting passengers, airlines, and airport staff.
What Happened at Austin-Bergstrom International Airport?
On the morning of May 21, 2025, the FAA issued a ground delay at Austin-Bergstrom International Airport, starting at 11:47 a.m. local time. The agency cited “staffing issues at the air traffic control tower” as the cause. The ground delay was set to last until 9:59 p.m., affecting all flights arriving in Austin from airports across the United States 🇺🇸.
Key facts from the day:
- Average flight delays reached 49 minutes, with some flights delayed up to 113 minutes.
- By the afternoon, over 200 flights were delayed, and the longest delay stretched to seven hours and 45 minutes.
- A ground stop—which means no flights could land or take off—was briefly put in place at 3:55 p.m. before being lifted later.
- FlightAware tracked 184 delays at Austin airport during this period.
- Austin City Council Member Vanessa Fuentes used social media to warn travelers that “incoming flights from across the U.S. may be delayed.”
The impact was immediate and widespread. Passengers found themselves stuck on planes, waiting at gates, or stranded at other airports, all because there simply weren’t enough controllers to safely manage the airspace over Austin.
Why Did This Happen? The Air Traffic Control Staffing Shortage
The root cause of the disruption was a critical shortage of air traffic controllers at Austin-Bergstrom International Airport. Air traffic controllers are responsible for safely guiding planes as they take off, land, and move through the airspace. Without enough controllers, the FAA must slow down or even stop flights to maintain safety.
Details about the staffing crisis at Austin:
- Normally, each tower shift should have 14 controllers. On May 21, there were as few as eight controllers on duty.
- As of January 2025, the FAA reported only 32 controller positions filled out of a target of 60 at Austin.
- In December 2024, there were 33 fully certified controllers, down from 35 in 2023.
- At least two controllers were out for medical reasons, and two more were reportedly leaving their jobs.
This shortage is not new. Austin-Bergstrom has faced repeated disruptions over the past two years:
- On March 21, 2025, flights from Dallas and Houston were temporarily halted due to staffing issues.
- During the 2024 year-end holiday season, Austin was among the top airports affected by controller shortages.
- Multiple ground stops have occurred in the past two years, a sharp change from previous years when such measures were rare.
According to analysis by VisaVerge.com, these ongoing disruptions highlight how staffing shortages can quickly ripple through the entire air travel system, causing delays and uncertainty for thousands of travelers.
How Does a Ground Delay Program Work?
A ground delay program is a tool the FAA uses when an airport cannot safely handle its usual number of arriving flights. This can be due to weather, equipment problems, or—as in this case—a lack of air traffic controllers. When a ground delay is in effect, flights headed to the affected airport are held at their departure airports until it is safe to allow them to proceed.
What does this mean for travelers?
- If you’re flying into an airport under a ground delay, your flight may be held at the departure gate for an extended period.
- Airlines may reschedule or cancel flights if delays become too long.
- Passengers may be stuck at connecting airports, sometimes for hours.
A ground stop is even more severe. It means all flights are halted—no takeoffs or landings—until the FAA lifts the restriction. On May 21, Austin experienced both a ground delay and a ground stop, compounding the disruption.
The National Air Traffic Control Staffing Crisis
While Austin’s situation is serious, it is part of a much larger problem affecting airports across the United States 🇺🇸. The FAA estimates that the country needs to hire about 3,000 additional air traffic controllers to be fully staffed. The shortage has been building for years, as experienced controllers retire and not enough new ones are trained to replace them.
Other airports facing similar issues:
- Newark Liberty International Airport has become a symbol of the crisis, with the FAA recently cutting 25% of flights due to staffing shortages.
- The problem is described as “part of a broader crisis that has permeated the transportation sector over the past decade.”
The shortage is not just about numbers. Training a new air traffic controller is a long and complex process. It takes three to four years to fully train and certify a controller, according to Transportation Secretary Sean Duffy. This means that even with aggressive hiring, relief will not come quickly.
Federal Response: What Is Being Done?
The federal government, under the Trump administration, has acknowledged the seriousness of the air traffic control staffing crisis. Several steps are being taken to address the problem, but solutions will take time.
Key actions announced:
- Creating new air traffic control centers to spread out the workload.
- Updating technology to make controllers’ jobs more efficient.
- Accelerating hiring processes to bring in new trainees faster.
For Newark Liberty International Airport, the FAA announced specific measures on May 7, 2025:
- Adding three new high-bandwidth telecommunications connections between New York-based STARS and Philadelphia TRACON.
- Replacing old copper telecommunications with modern fiberoptic technology.
- Deploying a temporary backup system for added safety.
- Establishing a STARS hub at Philadelphia TRACON.
- Increasing controller staffing and maintaining training classes through July 2026.
While these steps are focused on the New York area, similar efforts are expected to be rolled out at other major airports, including Austin-Bergstrom International Airport.
Real-World Impact: What Travelers Need to Know
For travelers using Austin-Bergstrom International Airport, the staffing shortage means more than just inconvenience. It creates a pattern of unpredictability that can disrupt travel plans, business meetings, family events, and more.
Practical advice for passengers:
- Check your flight status with your airline before heading to the airport. Delays and cancellations can happen with little warning.
- Monitor the FAA’s official website (fly.faa.gov) for real-time updates on airport status and delays.
- Be prepared for longer wait times, both at the airport and on the plane.
- If you have a connecting flight, consider booking longer layovers to allow for unexpected delays.
- Stay in touch with your airline’s customer service for rebooking options if your flight is significantly delayed or canceled.
One passenger shared their experience of being stuck at Raleigh-Durham International Airport for hours because of the situation in Austin. Stories like this are becoming more common as the staffing crisis continues.
The Human Side: How Staffing Shortages Affect Real People
The impact of the air traffic control staffing crisis goes beyond numbers and statistics. It affects real people—travelers, airline employees, and the controllers themselves.
For travelers:
- Missed connections can mean lost business opportunities or important family events.
- Extended delays can lead to extra costs for meals, hotels, or rebooking flights.
- The stress and uncertainty of not knowing when you’ll reach your destination can take a toll.
For airline staff:
- Gate agents and flight crews must manage frustrated passengers and adjust schedules on the fly.
- Pilots may face longer duty days, increasing fatigue and stress.
For air traffic controllers:
- Working with fewer colleagues means longer hours and higher stress.
- Controllers are responsible for the safety of thousands of people every day, and understaffing increases the pressure.
What’s Next for Austin-Bergstrom International Airport?
The outlook for Austin-Bergstrom International Airport—and for airports across the United States 🇺🇸—remains uncertain. The FAA and the federal government are working to address the staffing crisis, but meaningful improvements will take time.
Key points for the future:
- Training new controllers takes 3-4 years, so immediate relief is unlikely.
- The FAA has committed to keeping the public informed through their fly.faa.gov website.
- When staffing or equipment issues occur, the FAA will “ensure safety by slowing the rate of arrivals into the airport,” which means delays will continue as needed to maintain safety.
Travelers should expect that delays and ground stops may happen again, especially during busy travel periods or if more controllers leave their positions.
What Can Be Done? Steps for Passengers and Stakeholders
While individual travelers cannot solve the staffing crisis, there are steps you can take to minimize the impact on your travel plans:
- Book direct flights when possible to avoid missed connections.
- Travel earlier in the day, as delays often build up in the afternoon and evening.
- Sign up for flight alerts from your airline and the FAA.
- Have a backup plan in case your flight is delayed or canceled, such as knowing alternative routes or nearby hotels.
For airlines and airport authorities, continued communication with passengers and coordination with the FAA will be essential to manage disruptions as smoothly as possible.
