The Content Delivery Handoff System enables a passenger's wireless device, operating in an airborne wireless cellular network, to receive selected content and to ensure continuity and/or completion of the content delivery when the aircraft reaches its destination before the entirety of the selected content is delivered to the passenger. This completion of content delivery can occur in a spatially and temporally disjunct manner where the delivery of the remainder of the selected content occurs at a terrestrial location or on a subsequent flight and at a later time.
