QF81 (SYD-SIN), the 1230 hours departure that is due to arrive at 1750 was badly late on 1 December (104 minutes tardy) and 3 December (189 minutes behind schedule arriving) while on 4 December the deficit was 38 minutes.
QF19, the now daily 1225 hours SYD-MNL however has taken the cake, with today's expected to depart at 1500 hours. In the last nine or ten days it's only been on time arriving on 5 and 6 December, but up to three hours late on other days. A shocker.
Occasionally an A332 appears to be substituted for these flights, presumably when A333s are unavailable.
That recent turnback of CGK-bound QF41 to Sydney probably didn't help timekeeping.
QF23 (1030 hours SYD-BKK, usually an A333) is expected to depart an hour late this morning.
B789 VH-ZNA should arrive on QF28 (ex SCL) in SYD at 1843 hours, 53 minutes late this evening.
A332 VH-EBV is on QF69, the 0920 hours MEL-DEL that should arrive at 1706, 36 minutes tardy.
A388 VH-OQD is on QF1 that should be on blocks at LHR at 0709 hours, 54 minutes behind schedule. It had arrived SIN last night 36 late at 2246 hours.
