Does Snow Cancel Flights? A Comprehensive Guide

Does snow cancel flights? Winter weather can wreak havoc on travel plans. If you’ve ever worried that a snowstorm could cancel your upcoming flight, you’re not alone. As soon as the first snowflakes start falling, flyers start wondering: will my flight get canceled because of the snow?

If you’re short on time, here’s the quick answer: Snow can, and often does lead to canceled or delayed flights due to reduced visibility and slick runways. However, not all snowstorms automatically ground planes; it depends on the intensity and accumulation.

In this comprehensive guide, we’ll cover everything you need to know about snow storms and flight cancellations. You’ll learn what causes cancellations in winter weather, how airlines decide when to axe flights, and what you can do to deal with a scrubbed trip.

What Makes Snow Dangerous for Flying

Reduced Visibility

One of the main reasons why snow can be dangerous for flying is the reduced visibility it causes. Snowfall can significantly decrease visibility both on the ground and in the air. Pilots rely on clear visibility to navigate and maintain safe distances from other aircraft.

When visibility is reduced due to heavy snow or blizzards, it can be challenging for pilots to see runways, other aircraft, and navigational aids. This can increase the risk of collisions and accidents.

It is not uncommon for airports to cancel or delay flights during heavy snowfall to ensure the safety of passengers and crew.

Slick Runways

Snow can make runways extremely slippery, posing a significant risk during takeoff and landing. When snow accumulates on runways, it can create a layer of ice, making it difficult for aircraft to gain traction and maintain control.

This can result in longer takeoff and landing distances, increasing the risk of accidents. To mitigate this risk, airports have snow removal equipment and procedures in place to clear runways and apply de-icing agents.

However, in severe snowstorms, these measures may not be sufficient, leading to flight cancellations or delays.

According to the Federal Aviation Administration (FAA), snow and ice on runways contribute to approximately 20% of all weather-related incidents during takeoff and landing.

In addition to reduced visibility and slick runways, snow can also affect other aspects of flying, such as degrading aircraft performance and affecting equipment functionality. It is crucial for airlines and airports to closely monitor weather conditions and make informed decisions to ensure the safety of passengers and crew.

How Much Snow Grounds Flights?

When it comes to determining how much snow can ground flights, several factors come into play. The decision to cancel or delay flights depends on the intensity and accumulation of snow, as well as the regional differences in weather conditions and airport infrastructure.

Light vs Heavy Snowfall

Light snowfall typically does not have a significant impact on flight operations. Airlines and airports have procedures in place to manage light snow, such as de-icing aircraft and clearing runways. However, heavy snowfall can pose a greater challenge.

As snow accumulates at a faster rate, it becomes more difficult to keep runways clear and maintain safe aircraft operations.

According to the Federal Aviation Administration (FAA), heavy snowfall with reduced visibility can lead to flight cancellations or delays. When visibility drops below a certain threshold, it becomes unsafe for pilots to take off or land.

Additionally, heavy snow can make it harder for ground crews to maintain airport operations, resulting in delays or cancellations.

Accumulation Thresholds

There is no specific accumulation threshold that universally determines when flights are grounded. Each airport and airline may have its own guidelines based on factors such as runway conditions, snow removal capabilities, and aircraft performance.

However, as a general rule, airports often start implementing snow removal measures when snow reaches around 2 inches (5 cm).

It is important to note that the type of snow also plays a role. Wet and heavy snow can accumulate faster and be more challenging to remove compared to light and powdery snow. Therefore, even a lower accumulation of wet snow may have a greater impact on flight operations than a higher accumulation of dry snow.

Regional Differences

Regional differences in weather patterns and infrastructure can significantly affect how much snow grounds flights. Airports in regions that experience frequent snowfall, such as northern areas or mountainous regions, are often better equipped to handle snow-related challenges.

They may have more advanced snow removal equipment and well-established procedures for managing winter weather.

In contrast, airports in regions that rarely experience snowfall or have limited resources for snow removal may be more prone to flight disruptions when snow occurs. These airports may have lower accumulation thresholds for flight cancellations or delays, as they may not have the same level of preparedness and infrastructure as airports in snow-prone areas.

If you want to stay updated on flight cancellations or delays due to snow, it is recommended to check the official website or mobile application of the airline you are traveling with. Additionally, websites like FlightAware provide real-time flight tracking and information on flight status, including cancellations and delays caused by snow or other weather conditions.

Other Winter Weather Threats

While snow is often the primary concern when it comes to flight cancellations during winter, several other weather conditions can pose a threat to air travel. Airlines and airports closely monitor these conditions to ensure the safety of passengers and crew.


Icing occurs when supercooled water droplets freeze upon contact with an aircraft. This can affect the performance of the aircraft, leading to potential flight disruptions. Pilots need to be cautious of ice formation on the wings, tail, and other critical areas of the plane.

De-icing procedures are carried out to remove ice buildup and prevent any mishaps during takeoff and landing.

According to the Federal Aviation Administration (FAA), icing is responsible for a significant number of aviation accidents each year. Airlines have strict guidelines in place to assess the severity of icing conditions and determine whether it is safe to fly.

If the conditions are deemed too hazardous, flights may be delayed or canceled until the ice has been cleared.

High Winds

Strong winds can also disrupt flight operations, especially during winter storms. Crosswinds, in particular, can make it challenging for pilots to safely take off or land. Wind gusts can affect the stability of the aircraft and make it difficult to maintain control.

Airports have established maximum wind thresholds that determine when flights need to be canceled or diverted. These thresholds vary depending on the size and type of aircraft. Airlines rely on real-time weather updates and wind forecasts to make informed decisions about flight operations.

Extreme Cold

Extreme cold temperatures can impact aircraft performance and ground operations. For instance, freezing temperatures can affect the functionality of aircraft systems, such as fuel lines and engines.

Additionally, cold weather can cause issues with ground equipment, such as fuel trucks and de-icing vehicles.

Airlines and airports have protocols in place to ensure that aircraft and equipment are properly prepared for extreme cold conditions. This may include preheating the aircraft, using special fuel additives to prevent freezing, and ensuring that ground equipment is properly maintained.

It’s important to note that each airline and airport may have its own specific guidelines and procedures for dealing with these winter weather threats. Passengers are encouraged to stay informed about weather conditions and check with their airline for any potential flight disruptions.

How Airlines Decide to Cancel Flights

Internal Safety Policies

When it comes to deciding whether to cancel flights, airlines prioritize the safety of their passengers and crew. Each airline has its own internal safety policies that guide its decision-making process.

These policies take into account various factors such as weather conditions, visibility, runway conditions, and the ability to de-ice the aircraft. Airlines also consider the safety of ground staff and support personnel, as well as the availability of de-icing fluids and equipment.

For example, Delta Airlines has a comprehensive set of guidelines that cover a range of weather-related scenarios. Their decision to cancel flights is based on factors such as snow accumulation, ice accumulation, and forecasted weather conditions.

They also take into consideration the operational limitations of their aircraft, including the ability to safely navigate through snow-covered runways and taxiways.

Coordination With Air Traffic Control

Airlines work closely with air traffic control (ATC) to determine whether it is safe to operate flights during inclement weather. ATC provides real-time information about the current weather conditions at the airport, including visibility, wind speed, and any other factors that may impact flight operations.

ATC also plays a crucial role in managing the flow of air traffic during adverse weather conditions. They may implement ground stops or delay departures to ensure safe spacing between aircraft. Airlines rely on ATC’s expertise and guidance to make informed decisions about whether to cancel or delay flights.

Proactive vs Reactive Cancellations

Airlines have the option to proactively cancel flights or wait until a problem arises. Proactive cancellations are often made in anticipation of severe weather conditions or when it is clear that flying would be unsafe.

This allows airlines to minimize disruption and give passengers ample time to make alternative travel arrangements.

On the other hand, reactive cancellations occur when the airline is forced to cancel flights due to sudden changes in weather conditions or unforeseen circumstances. This can lead to last-minute cancellations and inconvenience for passengers.

Many airlines adopt a proactive approach to cancellations, prioritizing passenger safety and minimizing the risk of delays and disruptions. By closely monitoring weather forecasts and working in coordination with ATC, airlines aim to make timely and informed decisions about flight cancellations.

Ultimately, the decision to cancel flights is a complex one that takes into account a multitude of factors. Airlines have a responsibility to prioritize the safety of their passengers and crew, and their internal safety policies, coordination with ATC, and proactive approach to cancellations all play a role in ensuring a safe and smooth travel experience.
