Any idea what triggers this? I'm logged in.

I was searching last night for specific dates 4-5 months from now and it showed up for a several set of flights. Searched same exact criteria again 15 minutes later and no special pricing despite same set of flights (earlier showing discount) still available.

Searched same exact criteria again a couple of hours later and it shows up again. And then it's gone again after a period of time.

When it does show, it shows up whether I'm searching on app or website. When it doesn't show, it doesn't on either.
