Called JAL domestic and they gave me the 8 character confirmation code to pull up the receipt. Submitted that and the BP, along with proof of flight (nice feature! wish more carriers made it that easy) since the BP didn't have the originating airport on it.
AS credited as 100% + 25%COS + 100%RDM but no email response (typical in my experience with retro credits). My flight was not one of the AA international exceptions listed above, fwiw.
AS website hasn't been updated and still shows the same earning rate on JAL with no differentiation between international and domestic fares.
