Codeshare in one sentence
A codeshare is a flight sold under multiple airline names but operated by one airline.
Why airlines do it
- Extends each carrier's network without operating new flights.
- Lets travelers earn miles on their preferred program even on partner metal.
- Keeps alliances (Star, OneWorld, SkyTeam) commercially relevant.
How to spot a codeshare
On your boarding pass or itinerary, look for "Operated by [different airline]" — that's the carrier whose aircraft you'll actually fly on.
Examples:
- AA 6231 operated by British Airways — sold by American, flown by BA.
- DL 9402 operated by Air France — sold by Delta, flown by AF.
- UA 6234 operated by Lufthansa — sold by United, flown by LH.
What's the same
- Loyalty miles per the marketing airline's program (with some restrictions).
- Schedule and fare class.
What's different
- Service style and onboard experience match the operating carrier.
- Check-in is usually with the operating carrier.
- Baggage policies follow the operating carrier on most routes.
- Customer service for irregular ops is often the operating carrier.
Why a tracker helps
FlightyFlow automatically resolves codeshare flight numbers to the operating carrier's flight, so you can pin once and get accurate live data regardless of which booking number you used.
