I just flew QF1 with family. I was on a classic rewards ticket in Y and couldn't be bothered checking in on the app as I didnt have passports to hand for APIS. At the SYD check in in the first class section I was offered a cash upgrade for the first time ever - 1850 Y to Premium Economy per head.

I'm WP1 and this is the first time I've ever had an upsell like this. I was at the airport at T-4.5 because of bad planning on my part. In order to process I had to move from the F check in desk to the service desk then come back to finish checking bags.
