Cancellations and delays at Newark Liberty International Airport
In January 2025, a winter storm caused flight delays and cancellations at Newark Liberty International Airport, along with the two other major airports in the New York City metro area: LaGuardia and JFK. As of 2 p.m. on the day of the storm, there were 254 cancellations and 82 delays at Newark Liberty International.
In May 2025, Newark Liberty International Airport faced another crisis, this time due to thunderstorms. More than 230 flights were delayed and 100 were canceled as of 2 p.m. EDT. The airport has been plagued by equipment failures, staffing shortages, and outdated technology, leading to hundreds of flight disruptions. To address these issues, the FAA has created a task force with technology and telecommunications contractors. In addition, United Airlines has cut 35 round-trip flights per day from its Newark hub.
Newark Liberty International Airport has experienced multiple system outages in a short period, causing widespread delays and cancellations. One such outage in May 2025 impacted hundreds of flights, with a ground stop in place for about 45 minutes. The Federal Aviation Administration (FAA) confirmed that this was due to a telecommunications issue at the Philadelphia TRACON Area C, which guides aircraft in and out of Newark Liberty International Airport's airspace.
To compensate for staffing shortages and technical failures, the FAA implemented a ground delay to manage the flow of traffic at Newark Liberty International Airport, limiting the number of flights. This has caused frustration among travelers, with some expressing concern about the airport's ability to resolve these issues promptly.

Delayed departures at JFK Airport
Snowfall can cause significant disruptions to flight operations at JFK Airport, leading to delayed departures and cancellations. The impact of snow on flight schedules can vary depending on the severity of the weather conditions and the airport's capacity to manage snowy weather.
During a winter storm in February 2024, New York City's three major airports, including JFK, experienced cancellations and delays. At that time, 18% of flights at JFK Airport were canceled due to the snow. Similarly, in January 2025, a winter storm caused substantial delays at JFK Airport, with departures to Queens delayed by an average of two hours and thirty-seven minutes, according to the FAA.
Several factors contribute to delayed departures at JFK Airport during snowy conditions. Firstly, snow removal and runway clearing operations take time and can cause delays in aircraft takeoff and landing sequences. The airport's capacity to handle air traffic is reduced as runways may need to be closed intermittently for snow clearance. Additionally, de-icing procedures are implemented for aircraft and runways, further extending the time required for departure.
Another factor influencing delayed departures is the impact of low visibility on flight operations. Snowfall can reduce visibility, making it unsafe for pilots to navigate. As a result, departure procedures may be slowed down, and flights may be held at their gates until visibility improves to meet the required standards for safe takeoff.
To manage delayed departures during snowy conditions, JFK Airport implements ground delay programs to regulate the flow of outgoing traffic. These programs aim to space out departures and prevent congestion, ensuring the safe and efficient management of air traffic. Additionally, passengers are advised to check the status of their flights with their respective airlines and to anticipate potential delays or cancellations, especially during heavy snowfall.
To mitigate the impact of snow on flight operations, JFK Airport employs various strategies, including proactive snow removal and runway maintenance. The airport coordinates with airlines and ground handling agents to ensure efficient de-icing procedures, minimizing delays as much as possible. However, passenger safety remains the top priority, and delays in departures during snowy weather are necessary to ensure safe flight operations.

Cancellations at LaGuardia Airport
New York City's LaGuardia Airport is prone to cancellations and delays during winter storms. In February 2024, a snowstorm caused the cancellation of 40% of flights in and out of LaGuardia Airport as of 6:20 a.m., rising to 43% by 9:30 a.m. This was part of a wider disruption across New York City's three major airports, with Newark Liberty International and John F. Kennedy International Airport (JFK) also experiencing cancellations and delays.
During a winter storm in January 2025, LaGuardia Airport advised passengers that weather conditions were causing flight disruptions and recommended they check with their airlines to confirm the status of their flights. While specific cancellation figures for LaGuardia Airport were not provided during this storm, the airport did experience significant delays, with arriving flights delayed by an average of 1 hour and 46 minutes, and general departure delays of between 1 hour and 1 hour and 14 minutes.
The impact of snow on flight operations at LaGuardia Airport can vary depending on the severity of the weather conditions. Heavy snowfall during a winter storm can lead to a higher number of cancellations and longer delays, as the airport may need to allocate more time for snow removal and de-icing procedures. Additionally, reduced visibility and icy runway conditions can further contribute to flight disruptions.
To manage the impact of snow and ensure the safety of passengers and staff, LaGuardia Airport implements snow removal and de-icing procedures. These procedures can include ploughing and clearing runways, taxiways, and aprons, as well as de-icing critical surfaces to maintain safe operations. However, these necessary procedures can cause delays in flight operations, affecting both arrivals and departures.
Passengers travelling through LaGuardia Airport during winter weather are advised to check the status of their flights with their respective airlines and allow for extra time when travelling to the airport. It is also recommended to follow any travel advisories issued by the local authorities and stay updated on the latest weather forecasts. Being proactive and staying informed can help minimise the impact of potential cancellations and delays caused by snow at LaGuardia Airport.

Dealing with chain reactions of delays
Runway Maintenance and Operations:
NYC airports, including JFK, LaGuardia, and Newark, are well-equipped to handle snow and minimize delays. They employ various strategies, such as runway plowing and treatment, to keep runways clear and operational. However, significant snow accumulation may exceed the capacity for plowing, potentially forcing runways to close temporarily.
De-icing Procedures:
De-icing is crucial for flight safety in icy conditions. Special liquids are sprayed on aircraft surfaces to prevent ice formation and remove existing ice. However, de-icing can cause delays, especially if unforeseen circumstances require a second round of de-icing. Small airplanes are particularly affected, as they often lack the required de-icing capabilities and may be grounded during snowy weather.
Flight Crew Preparedness:
Flight crews play a vital role in managing snow-related delays. They must be aware of how snow and blowing snow impact visibility and aircraft acceptance rates. In some cases, diverting to alternate airfields or adjusting flight schedules to avoid snow events may be necessary to minimize delays and ensure passenger safety.
Passenger Communication and Flexibility:
Passengers should stay informed about their flight status and potential delays by checking with their airlines or the FAA's website. Airlines typically allow passengers to rebook without change fees if they anticipate significant cancellations or delays due to severe weather. Being proactive and flexible with travel plans can help reduce the chain reaction of delays.
Airport Coordination and Notices:
Effective coordination between airport authorities and various stakeholders is essential. Airports issue SNOWTAMs (special notices to airmen) to notify users of hazardous conditions due to snow, ice, slush, or standing water. These notices help flight crews, airlines, and passengers make informed decisions and prepare for potential delays.
By implementing these measures and maintaining clear communication, NYC airports can mitigate the chain reactions of delays caused by snow, ensuring safer and more efficient travel during winter weather events.

Travel advisories and rebooking
When it snows, New York City's airports—John F. Kennedy International Airport (JFK), LaGuardia Airport, and Newark Liberty International Airport—often experience delays and cancellations. During a snowstorm, it is common for airlines to allow passengers to rebook their flights without charging a change fee. These announcements are typically posted on a "Travel Advisories" page or a similarly named page on the airline's website.
Passengers can also expect delays when the weather clears, as there can be a "chain reaction" of delays and cancellations that interfere with later flights. This can happen when adverse weather conditions cause early flights to be delayed, creating a backlog of departures and arrivals that continues to affect operations even after the snow has stopped.
If you are travelling to or from New York during the winter, it is advisable to check for travel advisories and updates from your airline or the airport before departing for the airport. During severe weather, passengers may be advised to contact their airline to confirm the status of their flight. In some cases, travel advisories may recommend avoiding all non-essential travel, urging people to stay off the roads.
In the event of significant delays or cancellations, airlines typically offer the option to rebook your flight to a later date without incurring additional fees. This information is usually communicated through the airline's website or mobile app, and passengers may be able to receive updates via email or text message if they have provided their contact information during the booking process. It is important to remain vigilant and stay informed about the latest travel advisories and rebooking options to ensure a smooth travel experience during winter weather events.
