No need to SHOUT Flyer, I was trying to help!
The flights from both Brisbane & Perth arrive in Hongkong around 5pm. They would do the late night return departures back to Brisbane & Perth.
You havent looked at the new schedules from MAR 29 onwards!
The BNE and PER flights arrive into HKG at 6:05am and then it looks like they sit all day till 23:00ish Dep.
