Commercial airline passengers wait, and make their way through the ticketing level at Chicago's Midway International Airport Friday, May 26, 2023, in Chicago. U.S. airfares are, on average, 15% lower now than they were a decade ago, and 6% lower than this time last year. The same cannot be said for many other purchasing categories where prices are increasing due to inflation. (AP Photo/Charles Rex Arbogast, File)
