This film is believed lost.
The Air Circus opened 1 Sep 1928 at the Gaiety Theatre in New York City, as part of a program of Fox Film Corp. productions, all of which employed the Movietone optical sound process. The theater charged a premium admission price of $2.00 for adults. That same day, Motion Picture News heralded the film as "the first Movietone feature with dialogue to be released by any company." In addition to talking sequences, the picture included sound effects and music.
