If the flight is marketed by another airline such as AA and bears a code-share on the ticket it is not eligible for credit to AS but can be credited to AA.Therefore, BA52 from SEA-LHR marketed by BA and operated by BA is eligible for credit to AS while the same flight AA6232 marketed by AA and operated by BA is not eligible for credit to AS.
That is correct as per AS' written rules, however the experience by me and others here is that AS is more lenient than the written policy and will credit that AA6232 flight to Mileage Plan as BA52 upon submission of the pax's BA52 boarding pass. I've done this with AA, DL, & JL codeshare flights in the last year. All credited to AS. ^
