Been checking for award flights for fra to hkg in June, and when you select the date on the availability calendar there's a green seat icon on dates that show high chance of availability for that date. Unfortunately when the page loads, there is no available flight. And the calendar shows it was updated at 22:00 HK time (I checked multiple times within an hour of this updated time) Has anyone had this happen?

​​​​​​Did those seats get booked up real fast, or is it a glitch with not loading the award flight?
