What is the term for an agreement among airlines to cooperate on passenger transfers?

• A. Code-share agreement
• B. Interline agreement
• C. Joint venture agreement
• D. Cooperation agreement

Answer: (B)

Interline agreements are arrangements between airlines to cooperate on moving passengers and their bags between different carriers on itineraries that involve more than one airline. This enables through-ticketing, smoother transfers, and baggage handling as a single journey, even when multiple airlines are involved. It’s the term most closely tied to coordinating passenger transfers across carriers.

Code-share deals focus on marketing and operating the same flight under multiple brands, rather than the logistics of transferring passengers between airlines. Joint ventures are broader business alliances with revenue sharing and joint investment. A generic cooperation agreement is too broad and not specific to passenger transfers.
