The working title of the film was High over the Atlantic. Although there is a copyright statement in the onscreen credits, it was illegible on the viewed print, and the film was not registered for copyright at the time of its release. However, according to copyright records, the film was registered by Golden $howman$hip Group on January 5, 1987 under the number RE-319-630. The song "What Would I Do Without You," sung by The King Sisters, is heard as a jukebox tune in a bar. Hollywood Reporter news items indicated that Lumsden Hare was originally slated for the role of "Rev. Dean Halltree," but was later replaced by Frederic Worlock.
As noted in a May 1959 Hollywood Reporter item, Jet over the Atlantic marked the return to the screen of Ilona Massey after a nine-year hiatus. A May 12, 1959 Hollywood Reporter news item adds Maria Monay to the cast, but her appearance in the released film has not been confirmed. A Hollywood Reporter production chart indicated the film was shot on location in Spain as well as Mexico, but other sources indicate that Mexico, including Mexico City, was the film's location.
