Hi - I am researching possible trips to take using miles in 2015 (LAX to Tokyo, LAX to Shanghai, etc). No matter which date I pick, I don't see any First Saver awards available nor any partner flights other than Asiana.

Is Air China no longer participating? Last year I was able to book First with them with pretty generous availability.

Any thoughts? Is United hiding availability from certain partners?

Edit: Targeting a November timeframe for the trip
