Trying to construct a BKK/SIN-NRT-SFO/LAX business class award on JL using AS miles for 2nd week of July. While the transpacific segments are quite generous in availability, BKK/SIN-NRT segments are completely sold out across July and August in biz class. And to make matters worse even the economy segments are not coming up on the AS site when I tried to book a through ticket from BKK/SIN to SFO. Any chance of intra asia award space opening up on JL closer to travel?
