More than a thousand flights were canceled in the United States on Wednesday morning as a winter storm hit the country.
As of about 11:15 a.m. ET Wednesday, a total of 1,221 flights in and out of the US had been canceled, according to flight tracking site FlightAware. Regional carrier SkyWest, which operates through partnerships with United, Delta, American and Alaska Airlines, had canceled about 280 flights. Delta and Southwest had both canceled about 240 flights.
Minneapolis−Saint Paul International Airport and Denver International Airport were the most heavily affected, according to FlightAware. Detroit Metropolitan Wayne County Airport, Chicago O’Hare International Airport and Toronto Pearson International Airport were also experiencing disruption.
The flight disruption comes after winter weather alerts were issued across 29 states, including California, Minnesota and Maine, with warnings of severe icing, extreme cold and sleet as part of the three-day storm.
The Minneapolis area of Minnesota is at risk of picking up at least 15 inches of snow, with the National Weather Service in Minnesota’s Twin Cities warning the powerful storm “will bring widespread accumulating snow, with blowing and drifting snow mainly Wednesday through Thursday.”
