What is codeshare?

What is codeshare?

• A. A marketing program for shared loyalty between airlines.
• B. An agreement where multiple airlines market the same flight under different flight numbers.
• C. A method for letting passengers switch airlines without new tickets.
• D. A policy banning codeshare flights from certain airports.

Answer: (B)

Codeshare is an arrangement where two or more airlines market the same physical flight under each airline’s own flight number. In this setup, one airline operates the aircraft, while the other airline(s) sell seats on that same flight. Passengers can book with either airline and still travel on the same airplane, often earning loyalty miles with the operating airline or the marketing airline depending on the agreement. This broadens routes and schedules for travelers without adding extra flights. So the description that matches codeshare is when multiple airlines market the same flight under different flight numbers. The other choices describe related ideas that aren’t what codeshare means: a shared loyalty program is about marketing cooperation rather than the actual flight, switching airlines without a new ticket isn’t how codeshares work, and banning codeshare flights isn’t a standard practice.
