Codeshareaftaler

Codeshareaftaler, or codeshare agreements, are commercial arrangements in which two or more airlines publish and market the same flight under each airline's own flight number and brand, while a single carrier physically operates the aircraft. Passengers book a single itinerary that appears under multiple marketing carrier codes, but the operating carrier handles the flight’s operations.

How they work: The operating carrier performs the flight; marketing carriers sell seats on the same flight, sharing revenue according to negotiated terms. The booking systems display the flight as a codeshare, and passengers may earn and redeem frequent-flyer miles with the marketing carrier, subject to alliance rules. Check-in and baggage handling typically follow the operating carrier’s procedures, though policies may differ among partners. Codeshares enable through-service to destinations beyond a carrier’s own fleet and allow airlines to offer more connections without operating new flights.

Purpose and benefits: Codeshareaftaler expand network breadth and improve schedule connectivity, offering customers more convenient journeys and broader loyalty-program reach. For airlines, they provide access to partner networks, operational flexibility, and potential incremental revenue with lower capital and operating costs than launching new routes.

Risks and considerations: Managing schedules across multiple partners can be complex, and disruptions may affect connections or customer service. Passengers may experience confusion about responsibility for service levels. Regulatory and antitrust considerations apply in some markets, and alliances often underpin broader cooperative frameworks that govern codeshares.

Examples: Common codeshares include partnerships between Air France and KLM, Delta and Virgin Atlantic, United and Lufthansa, and Singapore Airlines with United, among others. In Danish contexts, the term codeshareaftaler is used to describe such arrangements.
