A charming farce set in 1960s Paris, "Boeing Boeing" follows journalist Bernard Lawrence as he juggles three high-flying girlfriends who are flight attendants on non-intersecting routes. His carefully constructed system of dating and deception begins to unravel when their airlines introduce new jet aircraft that alter the schedules, forcing his girls to converge in Paris at the same time. As chaos ensues, Bernard's life is complicated further by a fellow journalist and old acquaintance who takes advantage of the situation to manipulate him into leaving his comfortable Parisian lifestyle for a job in New York City.
