Codeshare Flights Explained: What They Mean for You
Quick answer
A codeshare flight is sold by one airline but flown by another. You book with your preferred carrier and get its flight number, yet a partner airline operates the aircraft. The key practical point: you normally check in with and fly on the operating airline — the one listed as "operated by" — so head to their desk, app, terminal and gate.

Why airlines use codeshares
Codeshares let airlines sell seats on routes they do not operate themselves, usually through alliances or bilateral partnerships. It widens their network on paper, gives you smoother connections between partner carriers, and often means a single ticket covering flights on two different airlines. For travellers, the main upside is convenience — one booking, connected bags, and coordinated timings.
How to tell if your flight is a codeshare
The giveaway is the phrase "operated by" followed by a different airline's name. You will see it in your confirmation, on the airline's app, and on the airport departures board. The flight number may carry your booking airline's code, while the plane itself wears the operating carrier's livery.
What a codeshare changes in practice
| Aspect | What to know |
|---|---|
| Check-in | Use the operating airline — their app, desk and terminal |
| Baggage | The operating carrier's allowance usually applies; check both if unsure |
| Seat selection | Often managed through the operating airline's system |
| Miles | Usually creditable to your programme, at a rate that can vary |
| Cabin & service | Match the operating airline, not the one you booked with |
Codeshares, delays and connections
Because a codeshare is a single ticket, the airlines involved are responsible for getting you to your destination. If a delay causes you to miss a connecting partner flight, you are generally rebooked at no extra cost — a big advantage over booking two separate tickets yourself. Passenger-rights rules still apply based on the operating carrier and route, so keep your booking reference and boarding passes handy if something goes wrong.

Tips for booking codeshare flights
- Note the "operated by" carrier as soon as you book so you head to the right desk and terminal.
- Check the operating airline's baggage rules, which may differ from the seller's.
- Add your frequent-flyer number to make sure you earn miles.
- Give yourself a comfortable connection when partners hand you off between flights.
- On the day, track the operating aircraft so you know its real status early.
