Actually the DL/AS mileage accrual reciprocity never applied to baggage allowances. So I doubt it will change in the future. I fly to AK quite a bit.
Try to use NW/DL for your first flight, the connect to AS and you will be exempt from baggage fees if you are DL medallion. You are always subject to the baggage fees/rules of the airline you first check in with.
On your return, if you fly AS within AK then connect to a DL/NW flight, only check your luggage on AS to your connecting point within AK (FAI/ANC) then recheck it there. AS doesn't charge for checked luggage within Alaska for the first three checked pieces.

thank you for that info. i will remember that as i plan on traveling to AK again next year. it is certainly a song/dance routine to avoid the fees these days. LOL
