If it says it is operated by BA, then it will be on a BA flight with BA onboard crew and the BA product. That is because they are part of the One World Alliance so sell tickets on each other's carriers in order to cover more of the globe.

When you see a flight marketed as “American Airlines operated by British Airways,” it means you are buying a ticket from American Airlines (AA), but the actual flight (the plane, crew, and service) is provided by British Airways (BA).

This is a common practice in the airline industry known as a codeshare agreement. Here’s what it means for you as a passenger:

Key Points:

1. Ticket Purchase: You book through American Airlines (on their website, app, or via a travel agent) and your ticket will have an American Airlines flight number (e.g., AA 1234).
2. Actual Operation: The physical aircraft, pilots, cabin crew, and onboard service are all British Airways. You will check in at a British Airways counter (or kiosk) at the airport and board a BA plane.
3. Why Airlines Do This: Network Expansion: It allows American Airlines to sell tickets to destinations they don’t fly to themselves, and vice-versa. Convenience: It creates seamless connections under one airline’s code, often with through-checked baggage. Efficiency: Airlines can fill seats without operating additional flights.
