BA marketed / codeshare, AA operated, BA table for EQM?
 

If I buy a BA marketed ticket, that is AA operated... I use the BA table for calculating EQM, right?

I know this question comes up all the time - in my defense, I did look it up in the FAQ and didn't see a clear answer :)

flight number = BA XXXX = BA table

Thanks. That was easy!

What happens when it is AA xxxx connecting to BA xxxx - but you bought both tickets on the BA website? How do EQD get calculated for the AA component?

By the AA tables, either on the portion of the fare that was allocated to AA, which you probably do not know, but which will become clear afterwards, or less often, in IRROPS(for example, maybe) it may be based on the AA 'Fare Unavailable" table.

Where you bought the ticket is completely irrelevant - what matters is the flight number that the flight is booked under.

AA flight number - earns as per AA table
BA flight number - earns as per BA table

There's no easy way (as far as I know) to know how the fare breaks out across segments

Thank you all kindly.
