For a one way load, it will wanna be good.
Err, it's not a one way load. The aircraft is operating HKG - SYD and then SYD - WTB - HKG. I dare say it will take a full load down to SYD from HKG, a part load out of SYD, then top it up to the max possible weight out of WTB.
It's happening tomorrow afternoon.
