Just received a tip that Alaska have confirmed a Partnership with Hainan Airlines. Mileage accrual is supposed to commence in the very near future, and reciprocal benefits are also in the works.
There have been
speculations in the past but most of us didn't really see much potential for the partnership, however it's good news that we now have more options for mainland china other than the limited CX network.
A tab for Hainan has also been added on the mileage plan website, although it doesn't contain any detail yet.
