Marcy Lewis is a young woman from Indiana with an ambition to become an airline stewardess and see the world. She takes an American Airlines training course and passes. Her first flight is nearly her last when, after inadvertently offending the pilot, Mike Jamison, she forgets the passengers' food. Mike's intervention earns Marcy a second chance. Marcy's home base is moved to Los Angeles and she finds an apartment with two friends from stewardess school. She meets a passenger, Mike Lawrence, who is pursuing a degree in science, then also nearly loses her job again by permitting a young passenger to keep her dog in the cabin, against the airline's rules. Marcy is suspended for a week. When a man named Mike Tracy helps give her stalled car a push, Marcy learns that he works for a Chicago advertising agency. An idea of hers, to let stewardesses endorse soap, pleases Tracy's client, and soon Marcy is invited by a photographer to pose for magazine ads herself. Mike J, Mike L and Mike T, all helping with Marcy's new apartment and all jealous of one another, suddenly realize that the photographer has other things in mind. They arrive in time to start a brawl, which makes the newspapers and gets both Marcy and pilot Mike J suspended from their jobs, as well as costing Mike T his account and Mike L his enrollment at the college. Marcy goes to the superiors of all three men personally to plead for their reinstatement. After she is successful, all three Mikes propose marriage to her. Not positive what to do, Marcy reacts favorably to Mike L's "I love you," and the other two Mikes concede that he's the guy for her.
