Airlines must pay you back for flight cancellations, major delays. How much will you get under new rule?

(NEXSTAR) – Airlines will soon be required to pay you back if they cancel your flight, delay you, make major changes to the itinerary, or don't deliver your checked bags on time.

The change was made official Wednesday when the Department of Transportation issued a final rule. "Passengers deserve to get their money back when an airline owes them — without headaches or haggling," Transportation Secretary Pete Buttigieg said in a written announcement of the new standards.
