If the body changes, is a round-trip ticket the same promise

Civilisational assumption
The people, events, figures, and contract terms are a synthetic premise. They are not statements of real cases or of current law. The source documents are the roots of the background and the norms and do not establish the premises of the scenario.
The question to decide
If your body's size can change during the journey, a round-trip ticket may not let you use the cabin you booked on the way back. Holding larger space reduces other passengers' seats, and charging for the actual space raises the cost of returning. How far does a round-trip ticket guarantee the return of a changed body, and who should bear the added space and cost?
