How to learn about an airport is closed
The fastest way to know if an airport is closed is to check the FAA's National Airspace Status page at faa.gov/air_traffic/nas. This page shows real-time closures and delays across U.S. airports. You can search by airport code (like LAX for Los Angeles or JFK for New York) and see whether the airport is open, closed, or operating under restrictions.
Your airline's website or app will also show closure information for your specific flight. Most airlines display airport status directly on the flight tracker or in your booking confirmation. If you have a flight booked, checking there first is often faster than searching the FAA site.
The National Weather Service (weather.gov) tracks weather-related closures by region. If an airport is closed due to snow, ice, or severe storms, the NWS page for that area will usually mention it. Local news stations also report major airport closures, especially if the closure affects hundreds of flights.
Key Takeaways
- The FAA's National Airspace Status page shows real-time closures and delays for any U.S. airport when you search by airport code.
- Weather is the most common reason airports close, and the National Weather Service tracks active weather events by region.
- Your airline's website or app will show whether your specific flight is affected by an airport closure.
- Airport closures usually last a few hours, but severe weather or equipment failures can keep an airport closed for a full day or longer.
- If your flight is cancelled due to airport closure, contact your airline directly — they handle rebooking and refunds, not the airport.
Why airports close and how long closures usually last
Airports close for three main reasons: weather, equipment failure, or security incidents. Weather closures are by far the most common. Heavy snow, ice, low visibility, or lightning can force an airport to stop all flights until conditions improve. These closures often last a few hours, though a major winter storm can keep an airport closed for most or all of a day.
Equipment failures — such as a broken runway light system, a malfunctioning air traffic control radar, or damage to taxiway infrastructure — can also trigger a closure. These closures vary widely in length depending on what broke and how quickly it can be repaired. A minor issue might be fixed in an hour; a major one could take a full day or more.
Security incidents are rare but can close an airport temporarily. These might include a security breach, an unattended bag, or a suspicious vehicle on airport grounds. Security closures usually last 30 minutes to a few hours while authorities investigate and clear the area.
What happens to flights when an airport closes
When an airport closes, all incoming and outgoing flights are held on the ground or diverted to other airports. Planes already in the air heading to the closed airport are usually rerouted to a nearby airport where they can land safely. Passengers on those planes may be bussed back to their original destination or rebooked on later flights.
Flights scheduled to depart from a closed airport are delayed until the airport reopens. Airlines do not cancel flights when ready when an airport closes — they wait to see how long the closure will last. If it becomes clear the airport will be closed for many hours, the airline will cancel affected flights and rebook passengers on other flights or offer refunds.
You will not hear about the closure from the airport itself. The airport does not contact passengers directly. Your airline is responsible for notifying you of delays and cancellations. Check your airline's website, app, or the phone number on your ticket for updates on your specific flight.
Regional airport closures and how they affect connecting flights
A closure at a major hub airport — such as Atlanta (ATL), Chicago (ORD), Dallas (DFW), or Denver (DEN) — affects hundreds of flights beyond just those landing and departing there. These airports handle connecting passengers, so a closure ripples through the entire airline network. A flight from a small regional airport to a major hub might be cancelled or delayed because the hub is closed, even though weather at the regional airport is fine.
If you have a connecting flight through a closed airport, your airline will rebook you on a different route or a later flight once the hub reopens. This can add many hours to your journey. The airline bears the cost of rebooking, meals, and hotel stays if the delay is their responsibility — which includes weather delays at major hubs, since airlines are expected to plan for weather.
Check the status of every airport on your itinerary, not just your final destination. If your connection point is closed, your entire trip is affected even if your departure airport is open.
How to stay informed during an airport closure
Set up flight alerts through your airline's app or website. Most airlines let you choose to receive notifications by text, email, or push notification when your flight status changes. These alerts will tell you when ready if your flight is delayed or cancelled due to an airport closure.
Follow the FAA on social media or check their website regularly if you are traveling soon. The FAA posts updates about major closures and significant delays on their Twitter account (@FAANews) and their website. Local airport authorities also post closure information on their websites and social media accounts.
If you are at the airport when a closure happens, ask an airline representative at the gate or ticket counter for the latest information. Do not rely only on the airport's departure board, which can lag behind real-time changes. Airline staff have access to current flight status and can tell you whether your flight will depart, be delayed, or be cancelled.
What to do if your flight is cancelled due to airport closure
Contact your airline as soon as you learn your flight is cancelled. You have three options: rebook on another flight at no charge, receive a refund of your ticket price, or receive a travel credit (airline credit) that you can use for a future flight. The airline must offer you all three options, though some airlines make the travel credit more attractive than the refund.
If the airline cannot rebook you on another flight to your destination within a reasonable time, they must cover meals and lodging while you wait. "Reasonable time" varies — some airlines define it as a few hours, others as longer. Ask the airline what they will cover before you spend money out of pocket.
Keep all receipts for meals, hotels, and transportation if you have to stay overnight. You will need them to file a reimbursement claim with the airline. Some airlines process these claims quickly; others take weeks. If the airline refuses to reimburse you, you can file a complaint with the Department of Transportation.
Frequently Asked Questions
Can I check if a specific airport will be closed before I book my flight?
No — airport closures happen due to weather or emergencies that cannot be predicted weeks in advance. You can check historical weather patterns for the time of year you plan to travel (for example, Denver gets snow in March), but you cannot know in advance whether an airport will close on your travel date. Once you have booked, check the FAA and weather forecasts a few days before your flight.
If an airport closes after I buy my ticket, do I get a refund?
If your flight is cancelled due to airport closure, yes — the airline must offer you a refund, a rebook on another flight, or a travel credit. Weather-related closures are considered "acts of God" in airline terms, so the airline is not required to pay you compensation beyond the refund or rebook. If you choose to cancel before the airline cancels, you may not receive a refund depending on your ticket type.
How do I know if my connecting flight is affected by an airport closure?
Check the status of both your departure airport and your connection airport on the FAA website or your airline's app. If either airport is closed or operating under restrictions, your flight may be delayed or cancelled. Your airline will notify you of changes to your flight, but checking proactively gives you time to contact them before the airport gets overwhelmed with calls.
What if I am already at the airport when it closes?
Stay in the airport or nearby. Do not leave the airport without asking an airline representative whether you will be rebooked on a flight that day. If the airport is closed for many hours, the airline will direct you to a hotel or provide a hotel voucher. Ask about meal vouchers and ground transportation as well — the airline covers these costs during weather delays.
