Oh, that's an interesting point -- I had just /assumed/ that the availability that I saw on Alaska's site was different from what they released to partners, but I guess I don't know that for sure. It's kind of tricky to find information about it online -- most of what I see is people using MileagePlan to get tickets on partners, not partners to book flights on AS metal.

I can find plenty of award availability on AlaskaAir.com, but none on AA.com -- though AA tells me "AAnytime awards for your origin and destination apply only for wholly American/American Eagle itineraries.", which I assume is because American Airlines flies that same route and is filtering out the Alaska results?

Time to give Emirates a call, I suppose!
