Award Calendar continues to misfire with great frequency.
As others have reported, I too have noticed that if you advance the calendar one month, and then return it back to the original month, the availability may change significantly.
As others have reported, I have frequently noticed that the calendar may display a low award as being available - yet when I click on that date - nothing shows up.
Just the latest example.
Searching for a segment - LAX-ERI on August 8 - the calendar SOMETIMES reports a low award available - but when I click on it, it always shows up as availability at the 40K (medium) level.
I will keep trying.
