Codeshare
Definition: A codeshare is a commercial arrangement where two or more airlines sell seats on the same flight under different flight numbers, allowing each airline to market the flight as its own.
Codesharing is one of the most common airline partnerships. When you book a flight that shows as, say, AA 5678, you may actually be flying on a British Airways aircraft operating as BA 123. Both airlines sell tickets on the same physical aircraft, but under their own flight numbers.
Codeshares benefit passengers by offering more flight options and allowing connections on partner airlines with a single booking. They also enable airlines to sell tickets to destinations they don’t physically fly to, expanding their apparent network.
However, codeshares can cause confusion about which airline’s product you’ll actually experience. The operating carrier determines the aircraft, seat, and onboard service. When booking business class, it’s essential to check the operating carrier to ensure you’ll receive the expected premium product. BookMyBusinessClass agents always confirm the operating carrier and seat type before booking.
