Avios redemption on Alaska – how to find PNR?

[maximus]

Hi all, I’ve snagged an Avios redemption in J from the West Coast to Hawaii on Alaska Air. BA’s e-ticket receipt only gives the BA PNR, but that doesn’t work on the Alaska Air website. How do I find the Alaska Air “booking code” for my reservation so that I can pre-book seats and check-in online?

In the past I’ve been able to get this relatively quickly by DMing @AlaskaAir on Twitter. Give them your surname, route, BA PNR, and date of travel in the initial message.
