I'm about to book a QR ticket on Priceline because I can't find the flights with a longer layover, mixed cabin and connection with QF after SYD.
Obviously, I would get the 157- ticket number, am I still able to upgrade at the airport or online with Qmiles or Qcredits? Does the ticket has to be bought on QR website or can I also upgrade my flights when I booked it on an OTA?
Thanks
