Absolutely, AS is definitely onboard that gravy train. But again, part of the lure they use is upgrades for upscale-ish (but not full on elite) customers. Might be a slightly different niche than DAL. That's my sense anyway, could be wrong.

And of course things can change.

I think one of the factors in pulling the trigger on international (via M&A) was the fact that One World doesn't actually work out great for AS's loyal customers. I've seen it myself, the one world partners tend to reserve their direct seats for themselves to sell at a premium... try to use points for international and it will route you all over the map on 2-3 airlines on three legs, basically on whatever seats are most likely to go empty anyway. Turns an 11 hour direct flight into a 30+ hour "adventure". Even though the "partner" is selling available seats on the direct flight.
