Yes, I had to find the date in the calendar at the bottom of the screen, and then set the check out date on the calendar on the top right and then click request to book.
Yeah I'll keep you posted
I searched "Anywhere * Homes & Boutique Hotels", price range $20 - $25 , unique stay is Plane.
There have been two listings all day, and then the Qantas one popped up (at $22)
I think maybe I got it? I haven't been charged, but I got an email saying "Your request was sent This is not a confirmed booking - at least not yet. You’ll get a response within 24 hours."
... fingers crossed
