Code-share agreements

Code sharing is an aviation business term for the practice of multiple airlines selling space on the same flights, where a seat can be purchased on one airline but is actually operated by a partner airline under a different flight number or carrier code. The code refers to the identifier used in flight schedule, generally the 2-character IATA airline designator code and flight number. The IATA code for Azerbaijan Hava Yollari is J2.

Under a code-share agreement, participating airlines can present a common flight number for several reasons, including:
Connecting flights - This provides clearer routing for the customer, allowing a customer to book travel from point A to C through point B under one carrier's code, instead of a customer booking from point A to B under one code, and from point B to C under another code. This is not only a superficial addition as cooperating airlines also strive to synchronize their schedules and coordinate luggage handling, which makes transfers between connecting flights less time-consuming.
Flights from both airlines that fly the same route — This provides an apparent increase in the frequency of service on the route by one airline.
Perceived service to unserved markets - This provides a method for carriers which do not operate their own aircraft on a given route to gain exposure in the market through display of their flight numbers.

Under a code-share agreement, the airline that actually operates the flight (the one providing the plane, the crew and the ground handling services) is called the operating carrier. The companies that sell tickets for that flight but do not actually operate it are called marketing carriers.
