Thanks for the reminder
Hvr and
BundyBear. Just went from 16C on the outbound to 5C as a humble Silver and have waitlisted upgrade to Business. Then I just went back in and Row 4 had opened up, so changed to 4C and cancelled the Upgrade. I won't need guesting into the SYD QC J Lounge, as I'll be collecting those attendees and heading over to the HQ. For my return flight on Sunday, the upgrade cleared instantly
I also checked with (former) Red Roo about what to do with hand luggage. She advised there aren't lockable storage available, however plenty of space out of sight - the campus will be quiet, so no issues.
I reckon we just store it in the QF Boardroom
