Up in the Air is a 2009 American comedy-drama film directed by Jason Reitman and co-written by Reitman and Sheldon Turner. It is a film adaptation of the 2001 novel of the same name, written by Walter Kirn. The story is about a corporate "downsizer" Ryan Bingham (George Clooney) and his travels.

Several scenes were also filmed in Detroit, Michigan; Omaha, Nebraska; Las Vegas, Nevada; and Miami, Florida.
