Hainan Airlines is having a nice sale from New York to Shenzhen. Flights start at $1888 but these fares credit nicely to Alaska Airlines at 100% EQMs and 200% RDMs so you would earn 16990 EQMs and 33980 RDMs.
We had a chance to fly Hainan Airlines a while back and it was a perfectly acceptable product. Here's a link to the full Trip Reports on their Boeing 737s as well as their long-haul Boeing 787s.
