DENVER, Colo (KKCO) Saturday's flight landed because of an unruly passenger. A United Flight headed from San Francisco to Chicago landed at DIA around 10:15 Saturday morning. A spokesperson couldn't say what type of disturbance was caused. The flight was able to leave Denver an hour later. Last Sunday, a Jetblue flight from New York to LA was diverted to Denver after authorities say a man groped a pregnant woman.
