How to learn about a specific airport is open
Most U.S. airports stay open year-round, but individual airports close temporarily for weather, emergencies, or runway maintenance. The fastest way to know if your airport is operating is to check the FAA's National Airspace Status page at faa.gov/air_traffic/nas/status. This page shows real-time delays and closures at major airports across the country.
You can also call your airport's operations line directly — the number is on the airport's website under "Contact Us" or "Operations." Airport staff can tell you whether departures and arrivals are running, whether specific runways are closed, and when service is expected to resume. This is faster than waiting for a website update if conditions are changing quickly.
Your airline's website or app will also show whether your flight is affected. If your flight is cancelled or delayed, the airline notifies you by phone, email, or text — whichever contact method you provided when you booked.
Key Takeaways
- The FAA's National Airspace Status page shows real-time closures and delays at U.S. airports, updated continuously throughout the day.
- Weather — snow, ice, thunderstorms, and fog — is the most common reason for temporary airport closures, usually lasting a few hours.
- Calling your airport's operations line or your airline directly gives you the most current information if you need to know right now.
- Runway maintenance and construction can close specific runways for days or weeks, but airports usually keep at least one runway open for emergency landings.
- Major holidays and severe winter storms sometimes affect multiple airports at once, so checking the FAA page before you leave for the airport saves time.
Weather closures are temporary and usually last a few hours
Snow, ice, thunderstorms, and dense fog are the main reasons airports close. When visibility drops below a certain threshold or runways become too slippery, the FAA orders a ground stop — all planes on the ground stay put, and incoming planes are held at other airports or diverted. These closures typically last two to four hours, though severe winter storms can keep an airport closed for a full day or longer.
Winter storms in the Northeast and Midwest cause the most frequent closures. Airports in Denver, Chicago, Boston, and New York are more likely to close in winter than airports in warm climates. The airport's snow removal equipment and staff size determine how quickly they can reopen — larger airports with dedicated snow teams can often resume operations faster than smaller regional airports.
Thunderstorms cause brief closures, often 30 minutes to an hour. Lightning grounds all aircraft, and once the storm passes, the airport reopens quickly. Fog closures depend on the airport's instrument landing system (ILS) — airports with advanced ILS can operate in lower visibility, while smaller airports without it may close until visibility improves.
Runway maintenance and construction can close specific runways for weeks
Airports schedule maintenance and construction work during slower travel periods, usually in winter or early spring. When a runway closes for repairs, the airport operates on its remaining runways. Most major airports have at least two runways, so one closure rarely shuts down the whole airport — it just reduces capacity and causes delays.
The FAA publishes a Notice to Airmen (NOTAM) for every runway closure, which airlines use to plan around the closure. You can search NOTAMs at faa.gov/notam if you want to know whether a specific runway will be closed on your travel date. Smaller regional airports with only one runway sometimes close completely during major maintenance, but they announce this months in advance.
Construction projects like new terminals or taxiway work can take months or years. These closures are scheduled and predictable, so airlines adjust their schedules accordingly. You are unlikely to show up for a flight only to find the airport closed for construction — the airline will have already rebooked you or cancelled the flight weeks earlier.
Emergencies and security incidents cause rare, sudden closures
Bomb threats, security breaches, medical emergencies on the tarmac, or accidents can force an airport to close for an hour or several hours while authorities investigate or clear the runway. These closures are unpredictable and rare. When they happen, the FAA when ready notifies airlines, and the airport's website and social media accounts post updates.
If you are at the airport when an emergency closure happens, airport staff will direct you to a holding area or back to the terminal. Airlines will rebook you on the next available flight once the airport reopens. You are not charged a rebooking fee for closures caused by emergencies or security incidents — the airline absorbs the cost.
How to prepare for possible closures before you travel
Check the weather forecast for your departure and arrival cities the day before you travel. If severe weather is predicted, check the FAA status page that morning. Arriving at the airport extra early on days with bad weather gives you a buffer if your flight is delayed or cancelled.
Sign up for flight alerts through your airline's app or website. Most airlines send notifications when your flight is delayed, cancelled, or rebooked. You can also set up alerts through flight tracking apps like FlightAware, which notify you of delays before the airline does.
If you are flying during winter or during hurricane season (June through November for Atlantic and Gulf Coast airports), build extra time into your schedule. A flight cancelled due to weather may not have another available flight until the next day, and hotels near the airport fill up quickly.
What happens to your flight if the airport closes
If your airport closes before your flight departs, your airline will either delay your flight until the airport reopens or cancel it. If the closure is short (a few hours), the airline usually delays. If the closure is long or the weather is expected to worsen, the airline cancels and offers to rebook you on a later flight at no charge, or refund your ticket.
You are not may have access to to compensation for weather-related cancellations under U.S. law — weather is considered an "act of God" beyond the airline's control. However, the airline must rebook you on the next available flight to your destination at no extra cost, or refund your ticket if you prefer not to fly.
If the airport closure is caused by something other than weather — a security incident, for example — the rules are the same: the airline rebooks or refunds you. Compensation rules vary by airline and by how long the delay is, so check your airline's policy on their website.
Regional airports close more often than major hubs
Small regional airports with one or two runways close more frequently than major hubs like Atlanta, Dallas, or Los Angeles. A regional airport in a mountainous or coastal area may close several times a year due to weather, while a major hub might close once or twice a year.
If you are flying into or out of a small regional airport during winter, check the weather and the FAA status page more carefully. These airports have less snow removal equipment and fewer alternative runways, so closures last longer. Connecting through a major hub instead of flying direct to a small airport can reduce your risk of weather delays, though it adds travel time.
Frequently Asked Questions
How do I know if my airport is closed right now?
Check the FAA's National Airspace Status page at faa.gov/air_traffic/nas/status, or call your airport's operations line. Your airline's website or app will also show whether your flight is affected. If you are already at the airport, ask an airline representative or check the departure board.
Can an airport close without warning?
Weather closures can happen with little warning if a storm moves in faster than forecast. Maintenance closures are scheduled months in advance. Emergencies like security incidents cause sudden closures, but these are rare. Checking the weather and the FAA status page the morning of your flight catches most surprises.
What should I do if my flight is cancelled because the airport is closed?
Contact your airline when ready — by phone, app, or website. The airline will rebook you on the next available flight at no charge or refund your ticket. If you are at the airport, go to your airline's ticket counter. If you are at home, call the airline's customer service line on your booking confirmation.
Do I get a refund if my flight is cancelled due to airport closure?
You can choose a refund or a rebooking on a later flight. The airline does not owe you compensation money for weather-related closures, but you are may have access to to either a new flight or your money back. Check your airline's policy for details on how long you have to rebook or request a refund.
Which U.S. airports close most often?
Airports in the Northeast and Midwest close most often in winter due to snow and ice. Denver, Chicago, Boston, and New York airports experience more closures than airports in warm climates. Small regional airports in mountainous areas also close more frequently than major hubs.
