Just because it is booked through the Alaska site does not mean the segments earn miles. There are plenty of instances --say SFO to BDL where the first flight/s are on Alaska and then the connecting one is solely an AA flight number. If that segment in question is a domestic flight with an AA flight number, no credit is earned.
It is not like UA's system where you can book a ticket through the UA site on Avianca issued as a 016 ticket and get award miles, PQM, PDQ.
