Airports rarely shut down completely, but partial closures and ground stops happen regularly

A full airport shutdown—where no planes land or take off—is uncommon. What happens far more often is a ground stop, where the Federal Aviation Administration (FAA) orders all aircraft to stop departing for a specific airport, usually for a few hours. During a ground stop, planes already in the air can still land, but new flights cannot leave their origin cities.

The distinction matters because a ground stop affects your flight differently than a runway closure or a weather event that shuts down one runway. A ground stop means your plane sits at the gate or circles in a holding pattern. A runway closure means flights divert to other airports entirely. A true airport shutdown—where the entire facility closes—happens only in extreme circumstances like hurricanes, tornadoes, or major infrastructure failures.

Key Takeaways

  • Ground stops, where no new flights can depart for a specific airport, last a few hours on average and are ordered by the FAA when arrival capacity is overwhelmed.
  • Weather events like thunderstorms, heavy snow, and low visibility cause most airport disruptions, though they rarely close an entire airport for more than a day.
  • Runway closures for maintenance or construction force flights to divert, but the airport itself remains open for other runways and airlines.
  • Check the FAA's website or your airline's app for real-time ground stop information rather than calling the airport, which is usually overwhelmed during disruptions.
  • If your flight is delayed or cancelled due to a ground stop, your airline must rebook you on the next available flight at no extra charge.

What triggers a ground stop

The FAA issues a ground stop when an airport's arrival capacity drops below the number of planes trying to land there. This happens most often during severe weather—thunderstorms, heavy snow, or fog that reduces visibility. When a runway floods or becomes unusable, the airport can handle fewer arrivals, and planes stack up. Rather than let hundreds of aircraft circle and burn fuel, the FAA stops new departures from other cities until the backlog clears.

A ground stop can also happen when air traffic control equipment fails, when a runway is temporarily closed for an accident or debris removal, or when a major airline has a system outage that prevents it from processing flights. During the COVID-19 pandemic, some airports briefly reduced operations due to staffing shortages, but this was not a shutdown—flights still operated, just at reduced frequency.

Ground stops typically last between two and four hours. The FAA lifts the stop once the airport's capacity recovers—the storm passes, visibility improves, or the backlog of planes clears. You can check whether a ground stop is in effect by visiting the FAA's website (faa.gov) and looking for "ground stops" or "airport status," or by checking your airline's app, which usually displays delays and ground stops in real time.

Weather events that disrupt or close airports

Thunderstorms are the single most common cause of airport disruption in the United States. A strong storm cell can close a runway for 30 minutes to an hour, triggering a ground stop at a major hub. Planes cannot take off or land during lightning, so even a brief but intense storm can back up hundreds of flights.

Heavy snow closes runways by reducing traction and visibility. Most major airports have snow removal equipment and can reopen a runway within hours, but if snow falls faster than it can be cleared, the airport may reduce operations to one runway or close temporarily. Winter storms in the Northeast or Midwest can disrupt service for a full day, but complete shutdowns are rare—airports prioritize keeping at least one runway open.

Fog and low visibility (below 1,000 feet) force pilots to use instrument landing systems, which slows the rate at which planes can land safely. This reduces capacity and triggers ground stops. Fog typically burns off by mid-morning, so delays from fog usually last a few hours. Hurricanes and tornadoes are the only weather events that typically close an airport entirely, and only for the duration of the storm—usually 12 to 24 hours.

Runway closures and construction

Airports sometimes close a runway for maintenance, repair, or construction. When this happens, the airport does not shut down—it operates on fewer runways. A major airport like Atlanta or Dallas might have four or five runways; closing one reduces capacity but does not stop flights. Airlines may reduce the number of departures or divert some flights to nearby airports, but service continues.

Planned runway closures are announced weeks or months in advance. Airlines know about them and adjust schedules accordingly. If your flight is affected by a planned closure, your airline will usually rebook you on a different flight before the closure date or offer a refund. Unplanned closures—due to a pothole, debris, or an accident—can happen without warning and may cause delays or cancellations for a few hours until the runway is inspected and reopened.

How to learn about an airport is closed or has a ground stop

The most reliable source is the FAA's website at faa.gov. Look for "Airport Status" or "Ground Stops" in the main menu. You can search by airport code (ATL for Atlanta, ORD for Chicago, LAX for Los Angeles) and see whether a ground stop is in effect, how long it is expected to last, and the reason for the delay.

Your airline's app or website will also show ground stops and delays. Most apps display real-time flight status and will notify you if your flight is affected. Calling the airport directly is usually not helpful during disruptions—phone lines are overwhelmed, and staff cannot predict when a ground stop will end.

Social media accounts run by the FAA and major airports post updates during disruptions, but these are less detailed than the official FAA website. If you are at the airport, check the departure boards or ask an airline agent, who has access to the most current information.

What happens to your flight during a ground stop

If you are already at the airport and your flight is subject to a ground stop, your plane will push back from the gate late or not at all. You will either wait at the gate or, if the delay is expected to be long, the airline may deplane you. The airline must provide food and water if the delay exceeds three hours on the ground (this is an FAA rule, though some airlines are more generous).

If you have not yet arrived at the airport, your flight may be delayed or cancelled. Check your airline's app or website before heading to the airport. If the ground stop is expected to last several hours, the airline may cancel the flight and rebook you on a later flight the same day or the next day at no extra charge. You are not may have access to to compensation for delays caused by weather or air traffic control decisions, but you are may have access to to rebooking.

If your flight is cancelled due to a ground stop, you can also choose to take a refund instead of rebooking. Some airlines offer a travel credit that does not expire; others offer a cash refund. Ask the airline which option is available to you.

When airports close for extended periods

A complete airport closure lasting more than a few hours is rare. Hurricanes are the main cause—airports in Florida, Louisiana, and the Carolinas close 24 to 48 hours before a major hurricane makes landfall and reopen once the storm passes and runways are inspected. During Hurricane Ian in 2022, several Florida airports closed for one to two days.

Tornadoes can force a brief closure (a few hours) while the airport is inspected for damage. Earthquakes, flooding, or a major infrastructure failure (like a control tower outage) can also close an airport temporarily. In all these cases, the closure is announced in advance or when ready after the event, and airlines cancel flights and rebook passengers.

A strike by air traffic controllers or airport workers could theoretically cause a shutdown, but this has not happened in the United States since 1981, when President Ronald Reagan fired striking controllers. Modern labor agreements include provisions that prevent strikes from shutting down the system entirely.

Frequently Asked Questions

Can my flight be cancelled if there is a ground stop?

Yes, if the ground stop is expected to last many hours or if your flight is scheduled during peak arrival times. The airline will cancel the flight and rebook you on the next available flight at no extra charge, or offer a refund. You are not may have access to to compensation for weather-related cancellations.

What should I do if I am stuck at the airport during a ground stop?

Stay near your gate and monitor your airline's app for updates. If the delay exceeds three hours, ask the airline for food and water vouchers. If the flight is cancelled, go to the airline's counter or use the app to rebook. Do not leave the airport unless you are certain your flight is cancelled for the day.

Do I get a refund if my flight is delayed by a ground stop?

No. The FAA does not require airlines to compensate passengers for delays caused by weather or air traffic control decisions. You are may have access to to rebooking on the next available flight, but not a refund or compensation unless the airline caused the delay.

How long do ground stops usually last?

Most ground stops last between two and four hours. Some clear in under an hour if the weather improves quickly. A few last six hours or longer if the weather is severe or the backlog of planes is very large. The FAA updates the expected duration as conditions change.

Will an airport close if there is heavy snow?

Heavy snow rarely closes an entire airport. Most airports have snow removal equipment and can keep at least one runway open. Operations may slow, and some flights may be cancelled or delayed, but a complete shutdown usually lasts only a few hours while snow is actively falling. Airports in cold climates like Minneapolis and Denver are equipped to handle heavy snow and rarely close.
