From aa.com:
"You can earn AAdvantage® miles when you fly on Alaska Airlines marketed and operated flights and Alaska Airlines codeshare flights operated by Horizon Air or other oneworld® carriers." (Emphasis added.)
unfortunately you can’t, fought this for about 6 months last year as I thought so too. It only works for “eligible routes” which was domestic and some Caribbean ones if I remember correctly.
