A major winter storm, named Blair, has wreaked havoc across the U.S., leading to the cancellation of over 10,300 flights, with significant disruptions reported in Washington, D.C., and other major cities. As heavy snowfall and ice alerts impact more than 60 million people, airlines have begun issuing travel waivers for affected passengers. Major airports, including Tampa International and Sky Harbor, have experienced delays and cancellations, with nearly half of the flights in Tampa being affected. Travelers are advised to check with their airlines for updated cancellation policies and local impacts due to cold weather. The storm continues to cause chaos, prompting operational adjustments from airlines like Delta.
