Thanks for the advice. I pulled the AS Confirmation Number after calling AS reservations. DL reservations customer service was totally unhelpful.
So to anyone taking DL codeshare on AS, advance warning that delta.com does not work doing an online check-in. You need the AS confirmation number and you need to do the online check-in on alaskaair.com.
