The Pilot Barbie & Traveling Kelly & Tommy Gift Set was separately boxed but shrink wrapped together with the Barbie Airplane.  The airplane, as well as Pilot Barbie alone, were also sold separately.  The Pilot Barbie & Traveling Kelly & Tommy Gift Set, that is attached to the Barbie Airplane, is a Sam's Club SSE.
