I have no status with AS. Previously I would use my AA EXP credentials if I wanted a free bag on AS, but otherwise would use my DL DM status. (And when the Alaska BofA card added free bags in 2015 I would just always use my DL DM status.)
It's a shame that the AA partnership with AS isn't as good as the old DL partnership. I used to regularly get upgraded to first on AS on some routes using my DL DM number, and even on mileage awards (where I shouldn't have been upgraded).
Anyways, I recently flew on AS with a premium cabin and realized AA EXP doesn't even get access to that. I guess I'll have to be satisfied with premium seats.
