WEST PALM BEACH, Fla. (CBS12) — A huge winter storm in the Northeast caused more than 5,800 flights to be canceled across the country on Monday, according to flight-tracking website FlightAware, and Florida airports were hit hard by the ripple effects.

A powerful nor’easter battering the Northeast on Monday led to thousands of flight cancellations across the country, with South Florida airports experiencing major delays and grounded flights as the storm shut down major routes into New York, Boston, and Philadelphia. Florida airports logged more than 1,000 cancellations statewide on Sunday.

At Palm Beach International Airport (PBI), several flights heading to the Northeast were canceled throughout the morning. Departures to Boston, Baltimore, and New York appeared on FlightAware as CANCELED, including Southwest Flight 3061 to Baltimore and JetBlue Flight 154 to JFK. Multiple other flights to Boston and Hartford were marked DELAYED as the storm continued to halt operations up north.

Miami International Airport (MIA) had nearly 150 flights delayed or canceled by early Monday, a number expected to rise as the nor’easter intensified. Travelers reported waiting in line for hours, some sleeping in terminals overnight, and others struggling to rebook as airlines last minute.

Fort Lauderdale-Hollywood International Airport (FLL) saw some of the most severe impacts; nearly 200 flights were delayed or canceled due to grounded aircraft and closed runways in the stormstricken Northeast, according to FlightAware. Most affected routes included New York City, Boston, Philadelphia, and Washington, D.C., where snowfall and high winds made takeoffs and landings impossible.

The nor’easter delivered 1–2 feet of snow, 70 mph wind gusts, and blizzard conditions to large portions of the Northeast, placing more than 35 million people under storm warnings. These conditions forced widespread airport closures and triggered cascading delays throughout the country, including in Florida.

Airlines began canceling flights as early as Saturday, with more than 3,400 cancellations already reported on Sunday, according to FlightAware, and additional disruptions expected into Tuesday as crews work to clear snowcovered runways

Travelers heading to PBI, MIA or FLL are urged to check their flight status either on the airports’ websites or on FlightAware before arriving at the airport and prepare for possible extended delays as airlines adjust schedules in the aftermath of the storm.
