NYC airports stay open during most weather and operational disruptions, but individual airlines cancel or delay flights
New York City's three major airports — LaGuardia (LGA), John F. Kennedy International (JFK), and Newark Liberty International (EWR) — do not close entirely except in the most severe circumstances. Even during hurricanes, blizzards, or other emergencies, the airports themselves remain operational. What changes is whether your specific flight departs or arrives on time.
When you hear "the airport is closed," what usually happened is that your airline cancelled your flight or the runway is temporarily closed to incoming traffic. The distinction matters because it changes what you do next and who you contact.
Key Takeaways
- NYC airports rarely close entirely; instead, individual flights are cancelled or delayed by airlines based on weather or operational conditions.
- Check your airline's website or your booking confirmation email first — that is where cancellations appear before any public announcement.
- The FAA's website shows ground stops and runway closures by airport, updated in real time, and tells you whether the airport itself is restricted.
- Port Authority of New York and New Jersey operates all three airports and posts alerts on their website when major disruptions affect airport operations.
- If your flight is cancelled, your airline is required to rebook you on the next available flight or refund your ticket.
Check your airline first — that is where cancellations show up
Your airline's website or app is the fastest place to see whether your specific flight is cancelled or delayed. Log in with your confirmation number or ticket number and look at your booking status. If the flight is cancelled, the airline will show a red banner or a status change to "Cancelled" on that page.
You can also call your airline's customer service line directly. Have your confirmation number ready. The airline can tell you when ready whether your flight is affected and what rebooking options exist. Do not wait for an email — the airline updates the website first, then sends notifications later.
The FAA website shows real-time ground stops and runway restrictions
The Federal Aviation Administration (FAA) maintains a live page at faa.gov/air_traffic/nas/status that shows whether any of the three NYC airports have a ground stop in effect. A ground stop means no flights can depart that airport until conditions improve, though flights already in the air can still land.
This page updates every few minutes and shows the reason for any restriction — weather, staffing, runway maintenance, or air traffic volume. If you see a ground stop listed for your departure airport, your flight will be delayed at minimum. If you see a ground stop at your arrival airport, your flight may be held on the tarmac or diverted.
The FAA page does not tell you about individual flight cancellations; it only shows airport-wide restrictions. For your specific flight, you still need to check your airline.
Port Authority alerts cover major disruptions affecting all three airports
The Port Authority of New York and New Jersey operates LaGuardia, JFK, and Newark. When a major event affects airport operations — a power outage, a security incident, a terminal evacuation, or severe weather — the Port Authority posts alerts on panynj.gov and on their social media accounts.
These alerts are for situations that affect the airport itself, not individual flights. If you see a Port Authority alert, it means something has disrupted normal airport operations, and you should expect widespread delays or cancellations across multiple airlines. Check your airline's website afterward to see how your flight is affected.
What "airport closed" actually means in practice
An airport closure is extremely rare. It happens only when conditions make it unsafe for any aircraft to operate — for example, a major hurricane with sustained winds above a certain threshold, or a security threat that requires evacuation. Even then, the closure is usually temporary, lasting hours rather than days.
More commonly, you will see a ground stop, which prevents departures but allows landings. Or you will see runway restrictions, which limit how many planes can take off or land per hour. Both of these slow traffic without closing the airport entirely.
If your flight is cancelled because of weather or airport conditions, your airline must rebook you on the next available flight to your destination at no extra charge, or refund your ticket if you prefer not to travel.
How to stay updated while you wait
Set up notifications on your airline's app or website so you get alerts about your specific flight. Most airlines let you choose email, text, or push notifications. This is faster than checking repeatedly.
If you are at the airport, ask an airline agent at the ticket counter or gate. They have access to real-time information about your flight and can tell you whether a delay is expected to clear or whether cancellation is likely. Do not rely on the departure board alone — it updates slowly and may not reflect the most recent changes.
If you are still deciding whether to head to the airport, call your airline first. A 15-minute phone call can save you a trip if your flight is already cancelled.
Frequently Asked Questions
How do I know if LaGuardia, JFK, or Newark is actually closed?
Check the FAA website at faa.gov/air_traffic/nas/status. If the airport is listed with a ground stop or closure, it will appear there. You can also call your airline — they will tell you when ready if the airport is closed to departures or arrivals.
Can my flight be cancelled even if the airport is open?
Yes. An airport can be fully operational while your airline cancels your flight due to crew shortages, mechanical issues, or other airline-specific problems. Always check your airline's website first, not just the airport status.
What do I do if my flight is cancelled?
Contact your airline when ready. They must rebook you on the next available flight at no charge or refund your ticket. Some airlines offer hotel and meal vouchers if the cancellation requires an overnight stay, though policies vary.
Do I need to go to the airport if there is a ground stop?
No. If a ground stop is in effect, your flight will not depart on time. Call your airline to ask whether they are rebooking passengers or cancelling the flight entirely before you head to the airport.
Where can I find alerts about airport closures?
Check the Port Authority website at panynj.gov, the FAA website at faa.gov/air_traffic/nas/status, and your airline's website. Follow the Port Authority's social media accounts for real-time updates during emergencies.
