A powerful winter storm severely disrupted air travel across the United States on Sunday, triggering extensive flight cancellations and delays at several of the country’s busiest airports. Hazardous conditions caused by snow, sleet and freezing rain affected travel plans nationwide as airlines struggled to maintain operations. Weather authorities warned that nearly 180 million people were at risk as the storm system stretched from the southern Rocky Mountains to New England. After impacting southern states, the storm advanced into the Northeast, where major cities were forecast to receive between one and two feet of snowfall, significantly limiting airport and ground operations.
The scale of disruption was reflected in aviation data, with more than 10,800 flights cancelled in a single day, according to flight-tracking platforms. Aviation analysts described the situation as the most severe cancellation event since the pandemic period. By Sunday afternoon, flight operations were largely suspended at several major airports, particularly in the Northeast. New York’s LaGuardia Airport temporarily shut down flight activity, while federal authorities confirmed that departures were grounded for several hours due to unsafe weather conditions.
Airports along the East Coast reported exceptionally high cancellation rates as the storm intensified. In Philadelphia, nearly all scheduled flights were called off, while LaGuardia Airport saw more than 90 per cent of its services cancelled. John F. Kennedy International Airport in New York also experienced widespread disruption, with close to four-fifths of flights grounded. Similar conditions prevailed at Ronald Reagan Washington National Airport, where all departing services were cancelled for the day, highlighting the storm’s extensive impact on air travel corridors.
Major airline hubs beyond the Northeast were also affected, including Dallas-Fort Worth, Charlotte, Atlanta and Philadelphia. Several leading airlines cancelled hundreds of flights each as crews, aircraft and airport resources were displaced by weather conditions. Industry experts indicated that recovery from such large-scale disruptions could take several days, warning that delays may continue even for travellers flying through regions not directly hit by the storm, due to interconnected airline networks and aircraft rotations.
Passengers impacted by cancellations were advised to contact airline customer service through airport counters, phone lines or online platforms to explore rebooking options. Most airlines typically offer rebooking on later flights without additional charges, subject to seat availability. Travellers were also reminded that if a cancelled flight is no longer needed, airlines are legally required to issue full refunds, including for non-refundable tickets and unused add-on services. While alternative airline bookings may be possible, carriers are not obligated to transfer passengers to competing airlines.
