Quick summary
A sinkhole discovered near Runway 4/22 at LaGuardia Airport on May 20, 2026, forced an immediate closure of one of the airport’s two main runways, triggering 197 cancellations and 168 delays by Wednesday afternoon. The Port Authority of New York and New Jersey confirmed the sinkhole was found during a routine morning inspection around 11 a.m. ET, with emergency construction and engineering crews dispatched to the site. The FAA simultaneously slowed inbound traffic due to thunderstorms forecast for later in the day, compounding the disruption.
No repair timeline has been announced. With only one runway operational and storms approaching, the cascade is not over — travelers with flights tonight face the highest exposure.
LaGuardia is running on one runway today, and the numbers are already severe.
The Port Authority confirmed the sinkhole appeared near Runway 4/22 — one of only two runways at the Queens, New York, airfield — during a standard morning inspection. The runway was shut down immediately. By Wednesday afternoon, 197 flights had been cancelled and departures were averaging 98 minutes late, with 168 additional delays logged across the airport.
The FAA moved to slow arrivals into LaGuardia because of both the runway restriction and incoming thunderstorms, a combination that turns a manageable single-runway operation into something much harder to recover from. The Port Authority has not said what caused the sinkhole, how large it is, or when Runway 4/22 will reopen.
Travelers with flights at LGA today — particularly those connecting onward through the Northeast corridor — should treat this as an active disruption requiring immediate action, not a situation to monitor from the departure lounge.
What the runway closure means for LGA operations right now
LaGuardia is one of the most capacity-constrained airports in the United States. It has no slack. Two runways handle everything — domestic mainline, regional feeders, and the dense shuttle traffic to Boston and Washington — and the schedule is built to the edge of what the field can absorb on a normal day. Losing Runway 4/22 cuts that capacity roughly in half.
The Port Authority confirmed it is coordinating with airline partners and urged all passengers to check directly with their carriers before traveling to the airport. Official statements confirm the closure and the warning to travelers. No injuries have been reported.
Historical precedent is not reassuring. Runway-area sinkholes at Dallas/Fort Worth in 2015 and at a California regional airport in 2024 resulted in closures ranging from several hours to multiple days, depending on the depth of subsurface damage. LaGuardia’s repair timeline remains entirely open-ended as of this writing.
This is also not LaGuardia’s first serious runway incident in recent months. A runway collision in March 2026 killed two pilots and exposed critical gaps in the airport’s surface detection systems — a reminder that LGA’s operational margins leave little room for compounding failures.

Your rights when the airport — not the airline — causes the cancellation
This is where many travelers get caught out. A sinkhole is an airport infrastructure failure, not an airline operational decision — and that distinction matters for what you are owed.
Under US DOT rules, airlines are not required to pay cash compensation for delays caused by airport infrastructure or weather. But the refund obligation is firm: if your airline cancels or significantly changes your flight and you decline the rebooking offer, you are entitled to a full refund of your unused ticket and any optional fees paid — regardless of the cause. That rule applies here. The DOT’s airline consumer refund guidance and 14 CFR Part 260 govern this directly.
Premium credit cards can fill the gap that DOT rules leave open. Chase Sapphire Reserve and Capital One Venture X typically trigger trip delay coverage after a common-carrier delay of at least 6 hours or an overnight stay — covering meals, hotels, and incidentals up to policy limits. Amex Platinum and Amex Gold travel protections depend on the specific covered-reason definition in your benefit guide; infrastructure-related delays are often covered if they meet the policy threshold. File through your card issuer’s benefits portal with your itinerary, the airline’s delay notice, and all receipts.
Steps to take right now, by situation
LaGuardia is operating on one runway with storms incoming and no confirmed repair timeline — the window for proactive rebooking is narrowing by the hour.
- If you have a LGA flight today: Open your airline app immediately and check for a same-day waiver. Delta, American, and Southwest all serve LGA and typically issue travel waivers during declared disruptions — these let you rebook without a change fee. Compare JFK and Newark (EWR) departures for the same city pair; both offer more rebooking depth and are not operating under the same runway restriction.
- If you are connecting through LGA: Do not assume a protected connection will hold. Ask your airline for reaccommodation on the earliest available nonstop to your final destination rather than a rebuilt connection — a second LGA touch point today is a liability.
- If you are already at the airport or airside: Stay airside if possible and monitor gate changes continuously. Request reaccommodation at the gate or airline service desk; phone queues will be long. Ask specifically for the earliest nonstop, not the next available LGA departure.
- If your flight is cancelled and you decline rebooking: You are entitled to a full refund under DOT rules — including any seat upgrade fees, checked bag fees, or other optional charges. Request this in writing through the airline’s app or customer service portal.
- If you paid with a premium card: Start your delay or trip interruption claim as soon as you have the airline’s delay notice. Keep every receipt — meals, hotel, ground transport. File through Chase, Amex, Citi, or Capital One’s benefits portal before the claim window closes.
Watch: The Port Authority’s next public statement on Runway 4/22 repair status — expected later today or overnight — will determine whether disruptions clear by Thursday morning or carry into the next full operating day.
Questions? Answers.
Is LaGuardia Airport closed entirely?
No. LaGuardia remains open and operating on its second runway, Runway 13/31. Only Runway 4/22 has been closed due to the sinkhole. Flights are continuing, but with significantly reduced capacity, active ground delays, and ongoing cancellations.
Am I entitled to a refund if my LGA flight is cancelled because of the sinkhole?
Yes, if your airline cancels or significantly changes your flight and you choose not to accept the rebooking, US DOT rules require a full cash refund of your ticket and any optional fees paid — regardless of whether the cause was the airline’s fault. The sinkhole being an airport infrastructure issue does not remove this obligation.
Can I use JFK or Newark instead of LaGuardia today?
Both are viable alternatives for most domestic city pairs served by LGA. JFK offers broader rebooking options and international connections; Newark is the primary Star Alliance hub in the New York metro area. Neither airport is operating under the same runway restriction as LGA today. Check your airline’s app for same-day waiver eligibility before booking a separate ticket.
How long could Runway 4/22 remain closed?
The Port Authority has not announced a repair timeline. Historical precedent from similar sinkhole events at other airports suggests closures can range from several hours to multiple days, depending on the extent of subsurface damage. Until a restore-by time is confirmed, travelers should plan around the disruption continuing into Thursday.
