Fly on AS, deposit miles to DL?
I used to fly on AS (for work) pretty frequently, but it's been quite a while (8 or 10 years?). Way back when, I could fly on AS, and designate my miles to go into my Northwest account (ah, Northwest...) - as long as I said so before the flight. Of course, Northwest is long gone now, gobbled by Delta.
I see that AS lists Delta as a partner.
My question: can I still do the same thing, that is, fly on AS and tell them to stash the earned miles in my Delta Skymiles account, rather than in Alaska's Mileage Plan?
Thanks.
