Thanks a lot- looks like I got some Qantas love there but it all went a bit strangely...
At around T-22 my online profile suddenly changed and I had 16K allocated instead of my old Y+ seat. I could even go in and change that to 17k because I don't want to sit right next to a bassinet seat, just in case there's a little cry baby in there.
The strange thing though is that the status of the upgrade still says "Requested" and I cannot check in online but get some error message. I just called them (through after the first beep- thanks Qantas!) and they told me it's all okay and apparently they need to manually release some upgrade voucher which can take until T-5. Never heard of that before and no txt message either but it looks as if I'm in J tomorrow, yuheee!
