Airlines Suspend Operations Across Northeast as Historic Blizzard Hernando Grounds Thousands of Flights

Severe winter weather has effectively severed the aviation arteries of the United States East Coast today, as a "potentially crippling" bomb cyclone, officially named Winter Storm Hernando, forced the cancellation of more than 10,000 flights through at least Tuesday.

Aviation hubs from Washington, D.C. to Boston are currently at a standstill. According to the latest data from FlightAware, Monday’s cancellations surged past 5,600 by midday, with nearly every major carrier suspending operations at New York’s John F. Kennedy International (JFK), LaGuardia (LGA), and Newark Liberty (EWR). In Boston, Logan International Airport (BOS) reported a staggering 93% cancellation rate as snow fell at a rate of 2 to 3 inches per hour.

A Region Under Siege

The National Weather Service (NWS) has issued blizzard warnings for a 700-mile stretch of the Atlantic seaboard, affecting over 40 million people from Maryland to Maine. In New York City, Mayor Zohran Mamdani announced a total ban on non-essential travel, leaving the city's streets and runways eerily deserted.

"The very high snowfall rates and potentially damaging wind gusts will travel nearly impossible from the DelMarVa Peninsula into southeastern New England,"  the NWS warned in a morning bulletin. Local meteorologists described the system as a "classic bomb cyclone," noting that visibility has dropped to near-zero in many metropolitan areas.

Airlines Shift to Recovery Mode

Major carriers, including American Airlines, Delta Air Lines, and United Airlines, have issued comprehensive travel waivers, allowing passengers to rebook flights through February 26 without penalty. However, the logistical challenge of repositioning aircraft and crews remains a significant hurdle for the remainder of the week.

"The safety of our customers and crewmembers is our first priority, and we will continue to track the storm to determine if additional operational adjustments will be required," JetBlue stated in an official release.

Delta Air Lines echoed the sentiment, warning that the system's movement could trigger further delays even after the snow stops falling. "The storm is also creating broader disruptions along the East Coast, and customers may experience additional schedule adjustments as the system moves through the region," the airline said.

Impacted Air Operations

While most flights at major hubs have been scrubbed, the following table represents key scheduled operations that have been suspended or significantly altered due to the blizzard conditions as of February 23, 2026.

The Road to Restart

The FAA has implemented ground stops at 13 regional airports, including Atlantic City International (ACY) and Long Island MacArthur (ISP), pending runway clearing operations. For travelers stranded at airports outside the storm zone, such as Orlando and Atlanta, the "ripple effect" of missing crews and grounded airframes is expected to persist for at least 72 hours.

"Blizzard conditions are expected and will make travel treacherous and potentially life-threatening," the New York branch of the US National Weather Service stated. As the sun sets on one of the most significant winter events in the last decade, the aviation industry remains in a holding pattern, waiting for the whiteout to fade.
