On Friday 6 March 2020, QF678 (VH-VXF), the 1105 hours ADL - MEL airborne at 1203) is arriving at 1337, 42 minutes behind its schedule.
The 1040 hours MEL - LAX QF93 did not depart until 1335 hours this afternoon, so expected same day arrival at gate should be 0835 hours, 145 minutes tardy. The aircraft is A388 VH-OQJ that arrived on QF94 at 0954 hours, only four minutes late. AS QF36 was still also an Airbus A380 (VH-OQH) that arrived MEL at 0604 hours (also four minutes late), it's unclear to me why OQH wasn't able to run 'the 93.'
The B744 on the 1135 hours SYD - JNB QF63 (VH-OEE) was also badly late, not pushing back until 1358 with same day arrival suggested as 1805 hours, 90 minutes behind schedule. This will delay the redeye return, QF64.
QF9, the 1650 hours MEL - PER - LHR has had both sectors cancelled on Friday 6 March 2020. Unusual, but the Thursday 5 March QF10 (1155 hours LHR - PER) was also cancelled, and its second sector, Friday's 1400 hours afternoon flight PER to MEL has also got the gong. It seems B789 VH-ZND (that arrived LHR on Thursday 5 March early morning) is still there, perhaps defective.
It's possible some from the abandoned QF9 (ex MEL passengers) may 'go forward' to SIN on QF37 at 1720 hours to connect to QF1 that's come in from SYD with destination LHR.
