I just checked my history and it was actually late Friday afternoon not Thursday in my case, but still, interesting. Perhaps the airline you're matching from is also relevant. Who knows?
I do have a number of upcoming bookings next year and am a Points Club member (granted, thanks to a generous credit card bonus) so had assumed that I'd be a reasonable candidate to finally switch over exclusively to QF, but we'll see. I'll admit, if they don't ask for more details to at least even consider me, I won't be super impressed and will probably go even more out of my way to instead stick with NZ and Star Alliance when life returns to normal (not that they care).
