Definition#

A codeshare is a commercial arrangement in which an airline (the marketing carrier) sells seats on a flight actually operated by another airline (the operating carrier) under its own flight number. The same physical flight carries multiple airline codes.

Why It Matters Operationally#

Codeshares allow airlines to offer a wider network without flying every route themselves. Passengers benefit from single-ticket itineraries, coordinated schedules, and shared frequent flyer benefits.
