Québec, Michigan, Florida, North Carolina, Illinois, Massachusetts, and more places in the U.S. and Canada are facing major travel disruptions as thousands of passengers remain stranded following the tragic LaGuardia Airport shutdown on March 22, 2026. The chaos was triggered by a fatal collision between an Air Canada Express CRJ‑900 regional jet and a Port Authority Aircraft Rescue and Firefighting (ARFF) truck on Runway 4, causing widespread cancellations, delays, and rerouted flights across multiple regions. While LaGuardia Airport partially reopened on March 23, it remains in limited operations with only a single runway open, as authorities continue their investigation into the incident and clean-up efforts on Runway 4.

In a devastating turn of events, LaGuardia Airport was thrown into chaos on March 22, 2026, following a tragic runway collision between an Air Canada Express CRJ‑900 regional jet and a Port Authority Aircraft Rescue and Firefighting (ARFF) truck. This unprecedented incident not only claimed the lives of the aircraft’s pilot and co-pilot but also led to widespread flight cancellations, massive delays, and travel disruptions affecting thousands across the United States and Canada. From Michigan to Florida, North Carolina to Québec, the ripple effect of the tragedy left passengers stranded in airports nationwide.

As of March 23, LaGuardia Airport (LGA) has partially reopened, though the recovery process remains far from over. While operations officially resumed around 2:00 PM local time, the airport is currently operating with limited capacity, utilizing only a single runway as Runway 4 remains closed for debris collection and an ongoing investigation by the National Transportation Safety Board (NTSB). The full scope of the disruption continues to unfold as authorities work to piece together what went wrong and restore normalcy to one of New York City’s busiest travel hubs.

What Happened at LaGuardia?

On the evening of March 22, Air Canada Express Flight 8646, a Bombardier CRJ‑900 regional jet operated by Jazz Aviation, was making its descent to LaGuardia Airport. The flight, which was coming from Montreal, Canada, was about to land when it tragically collided with an ARFF truck crossing Runway 4. The truck had been responding to an unrelated emergency involving a United Airlines flight. The crash occurred shortly before midnight, killing the pilot and co-pilot, both Canadian citizens. It was later revealed that the collision caused severe damage to the forward fuselage of the aircraft.

Grounded and Grounded: A Full Shutdown

In the aftermath of the crash, LaGuardia Airport was immediately shut down, with the Federal Aviation Administration (FAA) issuing a ground stop to prevent any further flights from taking off or landing. Emergency crews moved in swiftly, securing the scene, while investigators began piecing together what went wrong during the runway incursion. LaGuardia, one of New York City’s busiest airports, was essentially brought to a standstill for several hours as authorities scrambled to respond.

The Widespread Impact: Thousands Stranded

Within hours of the shutdown, the ripple effects began to spread across North America, particularly affecting U.S. and Canadian passengers. Flights were cancelled and rerouted, stranding thousands of passengers and causing an unprecedented level of travel chaos.

According to reports , 271 flights were cancelled at LaGuardia on March 23, spanning both arrivals and departures. This led to widespread delays and diversions, particularly to nearby John F. Kennedy International Airport (JFK) and Newark Liberty International Airport. Thousands of passengers found themselves stranded, unsure when they would be able to continue their journeys.

Places Affected

The effects were felt across multiple regions, with passengers stranded not only from New York, but also from distant places like Michigan, Florida, North Carolina, Illinois, Massachusetts, and Québec. The shutdown caused significant disruptions to flights arriving from or departing to these locations.

1. Québec: As the originating location of Air Canada Express Flight 8646, Québec was hit hard by the shutdown, with a large portion of passengers directly impacted by the crash and subsequent airport closure. Moreover, passengers with connecting flights through LaGuardia to international destinations or other parts of the U.S. were left in limbo, unable to board flights to their destinations.
2. Michigan: Travelers from Detroit Metro Wayne County and other Michigan airports were severely affected by LaGuardia’s closure, as Delta Air Lines, Republic Airways, and Endeavor Air — all major carriers operating out of Michigan — were forced to cancel and delay numerous flights.
3. Florida: Passengers traveling from Miami, Tampa, Orlando, and other Florida cities were impacted as flights were cancelled or diverted. Airlines like JetBlue, Southwest Airlines, and American Airlines were particularly affected, with many flights to LaGuardia unable to depart or being redirected to JFK or Newark.
4. North Carolina: Charlotte Douglas International Airport and Raleigh-Durham International Airport were also affected by the disruption, with several flights bound for LaGuardia grounded.
5. Illinois: Major airports such as Chicago O’Hare saw delays and cancellations as passengers traveling through LaGuardia to their next domestic or international destinations were stranded.
6. Massachusetts: Boston Logan International Airport also saw significant delays and cancellations, with affected travelers now looking at rebooking options or alternate connections via JFK or Newark.

Airlines Affected by the Shutdown

The following airlines saw the most significant disruptions to their operations due to the LaGuardia shutdown:

• Republic Airlines: As one of the hardest-hit carriers, Republic saw 64% of its flights cancelled, with 15% delayed. With major hubs in the Midwest, Republic’s passengers faced significant travel hurdles.
• Endeavor Air (Delta): 60% of Endeavor Air’s flights were cancelled, while 19% were delayed. Endeavor, a regional carrier for Delta Air Lines, saw a vast number of its routes between Detroit, Chicago, and other hubs affected.
• Delta Air Lines: With approximately 54% of its flights cancelled, Delta was among the top carriers impacted by the shutdown, stranding travelers from Florida, Michigan, and North Carolina.
• American Airlines: This major U.S. carrier faced 51% cancellations, with 19% delays, affecting travelers from Illinois, Florida, and Massachusetts.
• Southwest Airlines: Operating mainly on domestic routes, Southwest had to cancel 64% of its LaGuardia-bound flights, with 19% delays further compounding issues for travelers.
• Jazz Aviation (Air Canada): As the airline operating the ill-fated Air Canada Express flight, Jazz saw a dramatic impact, with 96% of its scheduled flights cancelled.
• JetBlue Airways: Despite being a prominent carrier in the New York area, JetBlue had to cancel 65% of its LaGuardia flights, with 26% delayed as the airport remained closed.
• United Airlines: United faced the least impact, with only 38% of its flights cancelled and 50% delayed, though passengers from the Midwest still faced disruptions.
• Spirit Airlines: As a low-cost carrier, Spirit had 61% of its flights cancelled and 19% delayed.

Other airlines like Air Canada, Mesa Air Group (UAL), Porter Airlines, and SkyWest were also affected, with cancellations or delays adding to the burden on passengers.

Flight Cancellations and Delays

The data collected from LaGuardia Airport revealed that several departures were impacted. Some of the cancelled flights included:

• JBU299 (JetBlue) to Orlando International (KMCO) at 9:25 AM EDT

The Investigation and Moving Forward

As authorities continue to investigate the crash, questions remain about the runway incursion and how the ARFF truck was allowed to cross an active runway while an aircraft was making its final approach. The National Transportation Safety Board (NTSB) has dispatched investigators to the scene and will likely release a preliminary report in the coming days.

Experts are also scrutinizing the coordination between air traffic control, ground crews, and the ARFF truck operators, as well as the airport’s safety procedures.

The shutdown of LaGuardia Airport and the devastating crash have shaken air travel in New York City and affected thousands of passengers in the U.S. and Canada. With key carriers like American Airlines, Southwest, JetBlue, Republic, and Porter Airlines grounded, the travel chaos is likely to persist for several days as operations return to normal.

Québec, Michigan, Florida, North Carolina, Illinois, Massachusetts, and more places in the U.S. and Canada are facing major travel disruptions as thousands of passengers remain stranded following a tragic runway collision at LaGuardia Airport on March 22, 2026. The shutdown occurred after an Air Canada Express CRJ‑900 regional jet collided with a Port Authority fire truck, triggering widespread flight cancellations, delays, and rerouting.

This tragedy also raises questions about airline safety procedures, runway traffic coordination, and the vulnerabilities that remain in modern air travel despite years of progress in aviation safety.
