The federal government is investigating the four largest U.S. airline frequent-flyer reward programs to examine their fairness, transparency, predictability, and competitiveness, the U.S. Department of Transportation (DOT) said in a Sept. 5 press release.
Secretary of Transportation Pete Buttigieg sent letters to the four airlines—American Airlines, Delta Air Lines, Southwest Airlines, and United Airlines—ordering them to hand over records and submit detailed reports addressing questions related to their rewards programs and practices by Dec. 4, 2024.
