The Protect Your Points Act of 2024 establishes new consumer protections for airline frequent flyer programs and airline co-branded credit cards. Airlines would be required to clearly display the dollar value of points and miles on their websites, eliminate expiration dates on accumulated rewards, allow consumers to transfer points between accounts without fees or limits, and show both dollar and point costs side-by-side when booking flights. Airlines would also need to give customers one year advance notice before making any changes that reduce the value of points, miles, or other rewards. The legislation applies to all major U.S. airlines that operate passenger flights and offer frequent flyer programs, and the Secretary of Transportation would oversee compliance with coordination from the Consumer Financial Protection Bureau, with most provisions taking effect within 90 days to one year of the law's enactment.
