The thread title is misleading.

AS has an interline baggage agreement with BA and BA has one with JU.

That is all that is required for the bags to be checked PDX-BEG

On separate tickets it is up to the originating carrier, AS. But, suggesting that the bags could be checked across carriers without an interline agreement is incorrect.
