Travelers at Newark Liberty International Airport face ongoing ground delays and flight restrictions as of July 28, 2025. The Federal Aviation Administration has imposed these measures due to air traffic controller shortages, technology failures, and Runway construction, with significant impacts on passengers, airlines, and airport operations.
The FAA’s latest order, issued June 6, 2025, sets strict flight caps at Newark Liberty International Airport. From June 16 to October 25, 2025, arrivals and departures are limited to 34 per hour. On weekends from September 1 to December 31, 2025, the caps drop further to 28 arrivals and 28 departures per hour. These restrictions aim to manage congestion and keep operations safe while the airport deals with staffing and technology problems.
Runway construction is another major factor. Repairs on Runway 4L-22R, a $121 million project, finished 13 days ahead of schedule in early June 2025. However, weekend construction will continue through the end of the year, further limiting airport capacity and contributing to ground delays.
Staffing shortages at the Philadelphia Terminal Radar Approach Control (TRACON), which manages Newark’s airspace, have caused repeated ground delays and even ground stops. As of July 2025, only 22 fully certified controllers and 5 supervisors are assigned to the area covering Newark, with 22 more in training. The shortage has been made worse by trauma leave among controllers following stressful technology outages in April and May 2025, when controllers temporarily lost the ability to communicate with or track aircraft.
To address these technology failures, the FAA has replaced about 90 miles of old copper cables with new fiber-optic lines between Philadelphia and New York. This upgrade, completed at the end of June 2025, improves reliability and reduces the risk of outages. The FAA has also added high-bandwidth connections and a temporary backup system to further strengthen the network.
Despite these efforts, Newark Liberty International Airport continues to experience some of the highest rates of summer flight delays and cancellations among U.S. airports. In summer 2025, the cancellation rate reached 6.6%, and average tarmac wait times climbed to 25.2 minutes. On the worst days, delays have averaged nearly four hours, with more than 250 delays and 150 cancellations reported in a single day during the spring disruptions.
The FAA’s flight caps are designed to balance safety and efficiency. By limiting the number of flights, the agency hopes to reduce congestion and lessen the impact of staffing and technology problems. Airlines, especially United Airlines—the largest carrier at Newark—have had to adjust their schedules. At the height of the crisis, United removed 35 round-trip flights per day. These changes are expected to affect holiday travel, especially on weekends through the end of 2025, including Thanksgiving and Christmas.
The FAA is working to recruit and train new air traffic controllers, but the process is slow because the job requires specialized skills. Trauma leave and burnout among current controllers remain a concern, as highlighted by union leaders. The National Air Traffic Controllers Association has called for more support and better staffing to help controllers cope with the stress.
Technology modernization is another key part of the FAA’s response. The switch to fiber-optic communications and the creation of a new STARS (Standard Terminal Automation Replacement System) hub at Philadelphia TRACON are meant to provide long-term stability and reduce the risk of future outages.
FAA and U.S. Department of Transportation officials, including Secretary Sean Duffy, have stressed that these measures are temporary and necessary for safety. They promise to keep working with airlines and the Port Authority of New York and New Jersey to find long-term solutions. Airlines have publicly acknowledged the challenges and have worked with the FAA to shape the current flight caps and strategies.
The Port Authority, which oversees Newark Liberty International Airport, continues to monitor passenger volumes—nearly 49 million travelers in 2024—and supports ongoing infrastructure upgrades. According to analysis by VisaVerge.com, these combined efforts are critical to keeping the airport running safely, even if they cause short-term inconvenience.
For passengers, the situation means planning ahead is more important than ever. Here’s what travelers should do:
- Check flight status often: Delays and cancellations are likely, especially on weekends and during busy travel times. Use real-time resources like the FAA’s Flight Status Portal and airline apps for updates.
- Plan for longer waits: With average tarmac wait times at 25.2 minutes, it’s wise to arrive early and be ready for last-minute changes.
- Expect holiday disruptions: Flight availability will be lower and delays more common during major holidays through December 2025.

The problems at Newark Liberty International Airport are not new. The Philadelphia TRACON has struggled with understaffing for years, and recent technology failures have made things worse. The FAA’s efforts to modernize technology and hire more controllers are part of a larger national push to fix long-standing air traffic control problems.
The crisis peaked in spring 2025, when a series of outages and a major runway closure led to widespread delays, cancellations, and a temporary ground stop at Newark. The FAA responded with emergency flight caps, faster construction, and technology upgrades.
Aviation experts say the FAA’s first plans to fix the problems were not enough, and more aggressive steps were needed. The current measures are seen as necessary but disruptive, with hopes that technology and staffing improvements will bring long-term benefits.
Political leaders are also watching closely. Senate Minority Leader Chuck Schumer has called for an inspector general investigation into the causes of the Newark disruptions, warning that similar problems could affect other airports if not addressed.
Looking ahead, the current flight caps at Newark Liberty International Airport are set to stay in place through at least December 31, 2025. The FAA hopes to finish all major technology upgrades and increase controller staffing by early 2026, which could allow for a gradual lifting of restrictions. However, the risk of further ground delays remains until these goals are met.
In summary, Newark Liberty International Airport is under strict FAA-imposed flight caps through the end of 2025 due to ongoing air traffic controller shortages, recent technology failures, and continued runway construction. The FAA and its partners are working on major upgrades, but delays and disruptions—especially on weekends and holidays—are likely to continue until at least early 2026. Travelers and airlines should keep checking official channels for updates and plan their trips with extra care. For more information, visit the FAA’s official Newark Airport updates.
