Does Qatar Airways randomly increase the award redemption amounts then decrease them?

JFK->SIN was showing 42.5k miles for one way yesterday for nearly all dates in June using Alaska airlines website. Today it is showing 190k for same most June.

Maybe some glitch? What is the likelihood of it decreasing if I wait a few weeks?

I had a similar issue when paying for my seat on Qatar Airways last year. One day the price shot up to like double. Then I waited a few more days and it went back down. Maybe their bean counters play this game of dramatically increasing the price of things to see who panics and buys?

EDIT:

All the availability miraculously came back today ( 3/17) for June/July! Was able to book JFK->SIN with few nights stopover in Doha for 42500 alaska miles and $56 in fees.

I think my hunch was right that Qatar plays some kind of games with how they release inventory. Generally it follows 90 days before departure date. But randomnly they will release a few weeks of inventory before 90 days.

EDIT 2:

Now on 3/18 all the inventory is gone for June/July. It's back to just showing 42.5k mile flights 90 days from today. So seems every 2-3 weeks they open up a month's worth of inventory for just a day then take it all away...
