Trivia

The show's theme music is a shortened version of the Rondo from "Piano Sonata in A Major" by Franz Schubert.

Tim Daly appeared as himself in an episode of Monk (2002) which starred Tony Shalhoub. He and Monk were passengers on a plane and there were several references to their roles on Wings.

The aircraft in the opening and closing credits (N121PP) is still in use with Cape Air Airlines of Hyannis, Massachusetts. One of Cape Air's primary destinations in its New England operation (they also operate in Florida, the Caribbean, and Micronesia) is, in fact, Nantucket. This particular aircraft exclusively serves the New England market, so on any given day it is probably flying in and out of Nantucket. When filmed for the credits, 121PP was in the livery of the now-defunct Express Air of New Bedford, Massachusetts. Shortly after the filming, it became the property of Cape Air and has been used in that airline's service ever since. Prior to Express Air, it was in service for Provincetown-Boston Airlines which went out of business the year before Cape Air started.

One of the producers, Roz Doyle, passed away from breast cancer in 1991. In homage, Roz Doyle became the name of Frasier's radio producer in the hit series, which takes place in the same "universe" as "Cheers" and "Wings," and has the same core creators.

Five characters from Cheers (1982); Norm, Cliff, Frasier, Lillith and Rebecca, made appearances on the show. No characters from Wings crossed over to any Cheers episodes, though Thomas Haden Church played an unrelated character on a Cheers episode prior to being cast on Wings.
