I am looking at booking an AA-operated flight from SEA to LHR as a BA code-share, crediting to AS. The flight number is BA1523.

My understanding is that I no longer have to worry about such codeshares now that AS is part of OneWorld.

But looking at https://www.alaskaair.com/content/mi...rtners-british

BA 1523 doesn’t fall into any of the earnings-eligible flight numbers. The same is true for an AS/Horizon operated feeder flight with a BA flight number. Is the webpage just not up to date? Would those flights require manual retro-credit by the MileagePlan, and hopefully they wouldn’t point to the page and say “so sorry, no miles for you”?
