Why was LaGuardia shut down after collision?

What happened at LaGuardia

New York’s LaGuardia Airport (LGA) was shut down after a fatal ground collision involving an Air Canada Express aircraft and a fire truck on the runway. The collision killed the pilot and co-pilot, and the airport disruption quickly turned into large-scale flight cancellations.

How it affected travelers

Reporting tied to the incident describes LGA canceling hundreds of flights after the crash, with authorities shutting down the airport and restricting operations for safety reasons. As a result, passengers faced cancellations and schedule changes at one of the busiest hubs in the U.S.

Why it matters

Runway collisions are rare but high-impact events because they suspend arrivals and departures while emergency responders investigate and while airport operators clear the runway and assess equipment and procedures. When the airport is closed, airlines can’t simply “reroute” on the spot—at minimum, they must cancel flights that would have needed LGA access, and they must also absorb crew and aircraft positioning issues.

For travelers, the practical takeaway is to monitor official flight status updates and be ready for cascading delays if you’re flying in or out of LGA during the disruption window. If you have a tight connection, you may need to rebook quickly because cancellations can spread through an airline’s schedule.

What to do next

• Check your flight status frequently on your airline’s site/app.
• Rebook early if your departure is likely to be canceled or heavily delayed.
• If you have onward connections, contact the airline promptly to see what rebooking options protect your itinerary.
