The term "codeshare" simply means that one physical flight may operate under several flight numbers. This facilitates the booking, marketing, selling, and promoting of routes that are operated by other carriers. It enables passengers to use all the airline clubs in the airline codeshares. They can use the same boarding practices for all flights sharing the code.
When you buy a ticket through a partner airline’s marketing service, your booking details will state the airline name and flight number with additional text like “operated by [the airline whose airplane you will be boarding]”. But you’ll still be booking or changing a codeshare flight with the non-operating (marketing) airline. The flight information monitors and overhead screens in the terminal will show both the marketing and operating airline flights for the same gate and departure time.

Advantages of airline codeshares

Airlines having codeshare agreements is a practice that provides various benefits to both the passengers and airlines. Here are just a few of them:

• Provides a one-stop reservation and ticketing facility.
• Allows you to book journeys that wouldn’t exist otherwise, since a single carrier often doesn’t operate the full route that you desire.
• Provides coordinated schedules for easier connections and saves your time.
• Gives airlines the ability to market the service of more destinations when they simply codeshare to a certain destination.
• Passengers can usually earn extra points and miles in the program of the airlines that have codeshare flights.

Potential issues with codeshares

There can be some pitfalls associated with booking and using airline codeshare flights and routes:

• The operating airline under a codeshare agreement may have baggage policy and pricing that differs from that of the marketing airline.
• Some airlines may sell a premium economy seat for a flight, but if the operating carrier does not offer premium economy, you may have to be seated in the normal economy seat without compensation.
