When you go online to book your flight, you might have noticed the term "codeshare flights" next to a ticket option. At first, it seems a little complicated and confusing. Who is actually flying the plane? Why does your ticket show a different airline but the boarding gate says another? Don’t worry—this isn’t a trick. This is a part of the travel system that airlines use to work together and make travelling more accessible to the passengers.
To make it simple, the following are the points that this guide will elaborate on:
A codeshare flight is simply a flight-sharing agreement between airlines. It means that one airline will operate the plane, but it is possible that the other airline can sell the tickets for the same flight under their own flight number. So imagine you bought your ticket with Airline A, but the actual crew and plane are of Airline B.
Think of it as teamwork. Airlines do not compete on all routes but cooperate. The process typically works in the following way:
A partnership agreement is formed between Airline A and Airline B.
The flight is scheduled and carried out by Airline A using its aircraft.
Airline B puts that flight in its own booking system with its own flight number.
The passengers can book from both airlines but will travel from Airline A.
Such an arrangement can be seen with the alliances like Star Alliance, SkyTeam and Oneworld, which link airlines around the globe to a single cooperative network.
Airlines aren’t doing this just for fun. Codeshare agreements give them great advantages both financially and strategically:
Long-haul networks: Instead of flying to every destination by themselves, airlines provide more destinations via partners.
Convenience of passengers: Customers are able to book flights with one airline but can travel to destinations far beyond that airline’s network.
Shared resources: Airlines will save on costs by avoiding duplicate routes.
International competition: A joint effort helps the airlines to compete better with larger competitors.
Concisely, it is a matter of effectiveness and coverage. In the absence of codeshare, the smaller or regional airlines would not be able to compete internationally.
To the passengers, the system makes life much easier:
Broader choices: You will be able to fly to more destinations without various bookings.
One-ticket simplicity: You can have two airlines, but you only have to make one booking.
Frequent flyer benefits: A large number of codeshare flights will enable you to earn miles or loyalty points with your preferred airline.
Stress-free transfers: Your baggage is usually checked until the last destination, hence saving you the extra hustle.
Of course, not all things about codeshare flights are perfect. Travelers are occasionally confused or inconvenienced by a few things:
Surprise airlines: You might be flying with a certain airline, and upon arrival at the airport, you discover that it is being flown by a different airline.
Varied service standards: The level of comfort, meals or in-flight entertainment could be different among the airlines.
Check-in regulations: It is common that you will have to check in with the airline that is actually flying the plane, not the one you booked.
Once you encounter a codeshare flight during your journey booking process, the following are some of the tips that will make the process easier:
Check the operating airline: It is always a good idea to make sure what airline is flying the plane, particularly when you are concerned about in-flight service or baggage restrictions.
Compare ticket prices: Sometimes the same codeshare flight can be cheaper on the other airline's website rather than that of the first airline.
Check baggage policies: The selling and operating airlines may have different baggage policies, and it is best to check before packing.
Take advantage of loyalty programs: When you are accumulating miles, be sure that the codeshare flights of the operating airline are covered by your frequent flyer account.
It is worth spending a few minutes to verify these facts before getting frustrated.
The codeshare flights can be very confusing to hear, yet in the real world, they are created to make the world a smoother and more interconnected place to travel. They provide the passengers with more destinations, transfers, and extra benefits, and enable airlines to operate more effectively.
The next time you book your flight and you see "operated by" in the information, you will know what it means. All you need to do is to verify the operating airline, compare the prices of the tickets and learn the baggage regulations and then proceed with the confirmation of the booking.
