The flight tracking apps are showing VH-ZNA as being due to operate this flight, having arrived close enough to time with QF22 from Dallas at 05:51 AEDT this morning.
ZNA as QF93 MEL-LAX departed at 1423 hours on Monday 27, 203 minutes tardy, but by 1434 had yet to become airborne.
A388 VH-OQB as QF1 was in the sky from SIN at 0152 hours this morning: LHR at gate arrival should be 08752 hours, 97 minutes behind schedule.
QF23 from SYD up to BKK is often quite a good runner but today with A333 VH-QPB, it was airborne at 1157 so gate arrival should be on the dot at 1700 hours local time, 50 late, ensuring that this evening's redeye QF24 will be similarly tardy, at least in its pushing back.
VH-QPF is on teh recently reintroduced SYD-HKG 'old stager' QF127. This timetabled 1015 hours flight took off at 1149 so expected gate arrival is 1734 in the late afternoon, a minute shy of an hour late. QF128 (the 1820 hours redeye back down to SYD) is optimistically expected to push back at 1850. Perhaps possible, but unlikely if previous observations are tyypical. Quite often these computer-generated estimates of when a delayed flight inbound will commence its retuin trip are overoptimistic. Some human intervention might improve the realism in these forecasts.
On four of its last seven nights, QF139 (the evening 1850 hours SYD across to CHC) has been more than half an hour late arriving at gate, meaning an 0200 check in for many hotel guests. Some businessmen may like this flight as it avoids 'wasteful' daytime travel but the disadvantage can be insufficient sleeping time before one fronts to an 0930 or even 1000 client meeting the next morning.
