Well, we got to the airport by 5:30am, and then had to wait till a little after 6am for the C/I to open.
We got the upgrades, so all is well. C/I took well over 10 minutes though.
There isn't any access to the QF 1st lounge though! It is closed until 9am....well after we are on the flight. We are using the business class lounge instead.
