Significant disruptions also hit major airport hubs in Dallas-Fort Worth, Charlotte, Philadelphia and Atlanta, home to the nation’s busiest airport.
What if my flight is canceled?
Big picture view:
If your flight is canceled, airlines will book you on another flight, but if multiple flights are canceled because of weather it may be a problem. Sometimes, they’ll partner with competing airlines to offer seats on other flights when the airline you’re flying with can’t accommodate.
According to the U.S. Department of Transportation, you are entitled to a refund if your flight is cancelled or significantly delayed – regardless of the reason – but only if you choose not to travel or accept travel credits, vouchers or other forms of compensation offered by the airline.

Millions under winter weather alerts nationwide
A massive and potentially historic winter storm is sweeping across the U.S., threatening over 245 million people from Arizona to Maine with heavy snow, crippling ice, and prolonged, life-threatening travel conditions through the weekend. Alex Pellom with Tennessee Emergency Management weighs in.
If you want to rebook your flight, do it as soon as you learn your flight is delayed or canceled. Try re-booking it quickly online, with the app or at the kiosk. If the airline’s phone number is backlogged, try calling through the international number – according to The Points Guy. If that doesn’t work, then try a ticketing agent. Speed is your friend here.
