Massive U.S. winter storm snarls travel as airlines cancel thousands of flights

A major winter storm barreling across the United States has severely disrupted travel, grounding flights and complicating airport operations nationwide.

Airlines canceled thousands of flights as heavy snow, sleet, and freezing rain spread across broad regions, including major East Coast metro areas and big connecting hubs.

Some airports were forced to scrap nearly all scheduled departures for the day, while carriers urged passengers to check flight status before leaving for the airport.

• Airlines expanded fee-free rebooking in many markets, but seats on remaining flights were limited.
• Consumers whose flights are canceled are entitled to a full refund, including non-refundable tickets and unused add-ons.
• Travelers were advised to use airline apps, online chat tools, and airport agents to secure rebooking and confirm baggage handling.
