Would very much appreciate any tips to improve the chances of obtaining an upgrade from Economy Class to Business Class on a fully paid ticket. The economy ticket from Sydney to London is fully paid and confirmed for departure on 19 July. Qantas have waitlisted the upgrade request (=90,000 points) and were unable to give me any further information as to the likelihood of confirmation, or how many available business class seats were available on the flight. They also advised that notification is not received should the waitlist come through and I would need to keep ringing to check status (or alternatively ask upon check-in). Is there anything more I can do to increase the chances of the waitlisted upgrade being confirmed. Many thanks.
