In the context of air travel, a specific term indicates a change of aircraft required to reach a final destination. This term signifies an intermediate stop where passengers disembark one airplane and board another to continue their journey. For instance, a traveler flying from New York to Tokyo might have this type of stop in Seoul. This necessitates transferring between aircraft and often involves changing terminals or even airports.
This type of itinerary is frequently employed for reaching destinations not served by direct flights or when direct flights are unavailable or prohibitively expensive. Historically, it has played a pivotal role in expanding the reach of air travel, enabling connections between smaller airports and major hubs, thereby creating a global network accessible to a wider range of travelers. Efficient scheduling of these itineraries is essential for airlines to optimize route networks and minimize passenger travel time. The ability to smoothly manage these transfers impacts passenger satisfaction and the overall efficiency of the air travel system.
