Was your flight canceled due to bad weather? What you need to know about rebooking, refunds and more

Hundreds of thousands of air travelers are facing potential flight cancellations and delays this weekend, the peak of summer travel, as thunderstorms threaten the East Coast, West Coast and points in between. Disruptions appeared to taper off Friday after thousands of flights were cancelled this week due to foul weather, particularly at United Airlines. Nearly 270 U.S. flights were canceled early Friday, according to flight tracking service FlightAware, and more than 1,100 U.S. flights were delayed. Staying calm — and knowing your rights — can go a long way if your flight is canceled, experts say. If you still want to get to your destination, most airlines will rebook you for free on the next available flight as long as it has seats, according to the U.S. Department of Transportation.
