New consumer protection rules will soon entitle airline passengers to automatic refunds when flights are canceled or significantly delayed, while also requiring airlines to reveal junk fees upfront.

In total, the new rules could save travelers $500 million annually, Department of Transportation Secretary Pete Buttigieg said Wednesday, describing the regulations as “the biggest expansion of passenger rights in the department’s history.”
