In Boeing-Boeing, according to press notes, "an architect living in Paris has been successfully juggling three flight attendant fiancées with his housekeeper reluctantly playing romantic air-traffic controller as they fly in and out of his swank bachelor pad. But when an old school pal visits, things get rather turbulent. Schedules change, flights are delayed and chaos ensues in this whirl of mayhem and matchmaking."
