Noticed something a bit strange -- I've been checking business class award space from NYC to BKK/HKT for Nov 2019. A couple weeks ago, there were plenty of flights available (saver and standard) on many days via Asiana, Austrian, Swiss, or Air China. Suddenly a few days ago, ALL the award flights on Asiana, Austrian, and Swiss are gone, not even Everyday Awards are available, leaving Air China as pretty much the only option. I'm not very experience with award redemption on United, so I'm hoping this is just a glitch, since I do see more options for closer in dates.
