Hi guys

I'm travelling to BNE from AKL. The flight leaves around 6pm.

There is a flight to SYD that leaves around 4pm

The check in will probably open 3-4 hours before the flight, as I will be at the airport early do you think I can check in once they open for the Syd flight or will I have to wait until 3-4 hours before mine?

I am QF Platinum, what is the best lounge to use qf or ek?

Thanks guys
