A watchable but non-essential comedy, this was about a formerly married couple (Christopher Cazenove and Margaret Whitton) who were brought back together as the dual hosts of a worldwide travel show called "Ticket To Ride" (which was also the title of "A Fine Romance" when it was shown in Britain, to avoid confusion with the sitcom of the same name - also produced by London Weekend, BTW). The series followed them and their assistants as they roamed the world, getting into mysteries and bickering all the way; all concerned were shooting for a "Hart to Hart"/"The Thin Man"/even "Remington Steele" feel, but the show only rarely achieved this.
Worse, as the show progressed the desperation became more and more evident; the leads certainly tried their best, but the scripts just didn't have it. (One episode was all too obviously designed to cannibalize footage from the pilot episode; it was painful - what worked for "Star Trek" and even for "Simon and Simon" didn't work here.) In the last episode "Ticket To Ride" was cancelled and our heroes found work on a morning show in Japan(!); the show never got recommissioned in real life either.
Incidentally, they found themselves in England and France an awful lot of the time, as I recall. Perhaps the credits give a clue: "The IndieProd Company for London Weekend Television and Television France 1 in association with Phoenix Entertainment Group." Happy trails...
