Airport Closure: LaGuardia (LGA), New York

LaGuardia Airport (LGA) is reporting a closure per FAA signal (severity 7.5), which will generate immediate flight cancellations and diversions affecting travelers transiting one of the New York metro area's busiest short-haul hubs. Traveler-care teams should anticipate rebooking demand across the Northeast corridor, with knock-on delays at EWR and JFK as passengers seek alternatives. Duty-of-care load is moderate-to-high given LGA's heavy business-travel profile; proactive outreach to travelers with same-day LGA itineraries is advised.
