My girlfriend flies less than I do. When we fly together she'll fly Delta with me, but sometimes she flies AA on her own. Should she be crediting all of her AA/Delta miles to Alaska so that he can attain the 25K status? (She wouldn't hit 25K on either airline alone, but perhaps combined)

If she achieves Alaska's equivalent of "silver"," will she receive the benefits of a Delta FO when she flies Delta? For example, will she improve her upgrade priority when traveling with me?

(Neither of us has ever actually flown on Alaska Airlines.)


Thanks!
