Thanks, we have enough USAir too. Have you flown Dragonair? Could get to LAX/SFO, use Cathay to HKG, then Dragonair.As you likely know, Nepal is in the 'Middle East/Indian Subcontinent' zone for AA and requires two awards if you want to go via HKG.
However it is in 'South and Central Asia' for US Airways awards and you can (for now) route either way or both. Just in case you also have US miles.
