What does law require for canceled airline flights, refunds, rebooking?

If you’re already at the airport, it’s time to multi-task to find another flight. Get in line to speak to an airline representative, and call or go online to connect to the airline’s reservations staff. It also helps to reach out on X, the site formerly known as Twitter.
