Air travel is getting worse, judging from the number of consumer complaints.

Consumer complaints about airlines nearly doubled in the first three months of this year compared with the same period last year and kept soaring in April and May, the U.S. Transportation Department said Wednesday.

Those are the latest figures from the government. The Transportation Department said information about complaints has been delayed because there are so many of them to process.

The department said it received 24,965 complaints about airline service in the first three months of the year, up 88% from the first quarter of 2022. Consumers filed another 6,712 complaints in April, up 32% from a year earlier, and 6,465 in May, an increase of 49%.
