An airline that offers flights to and from South Bend is coming under scrutiny thanks to a Florida newspaper’s report.

The Tampa Bay Times reports that an investigation of Allegiant Air found that their planes are “four times as likely to fail” as those operated by other airlines. The report cites 77 times Allegiant flights had to make unexpected landings for mechanical failures in 2015 alone, although none of those landings led to any reprimands or punishments by the Federal Aviation Administration.

Allegiant CEO Maurice Gallagher Jr. did not dispute the paper’s findings.

South Bend International Airport hosts Allegiant flights to and from Tampa/St. Petersburg/Clearwater, Florida; Punta Gorda/Ft. Myers, Florida; Sanford/Daytona Beach, Florida; Las Vegas, Nevada; and Phoenix/Mesa, Arizona.
