MINNEAPOLIS — A Delta Air Lines pilot suspected of drinking before his flight at Minneapolis-St. Paul International Airport has been arrested.

A report by airport police said the pilot had an “alcoholic container” in his possession and was suspected of being impaired. He was scheduled to fly to San Diego, California, Tuesday morning.

The pilot lives in Rosemount and was released about three hours after his arrest.

Airport spokesman Patrick Hogan said final toxicology results are pending, so the case is still under investigation.

Delta said its alcohol policy “is among the strictest in the industry and we have no tolerance for violation.” The Atlanta-based carrier said it’s cooperating with investigators.

The Federal Aviation Administration prohibits any pilot from flying within eight hours of drinking alcohol.
