Through fare

A through fare is a single fare that applies to transportation between an origin and a final destination, even when the journey includes one or more intermediate cities along the route. 

Instead of pricing each segment separately, the fare is constructed and filed as one continuous price covering the entire itinerary from start to end, while still allowing the traveler to pass through or connect in intermediate points. 

This type of fare is common in both airline and rail systems and is designed to simplify pricing for multi-segment journeys that are commercially treated as one trip.

It also supports network planning strategies by enabling carriers to compete more effectively on longer routes that involve connections, ensuring that travelers perceive the trip as a single product rather than separate legs.
