What I find interesting is that neither EK nor QR flights out of SYD seem to be impacted by this chaos. I was on EK413 on Friday night. The check-in process as well as Border Control and Security was a breeze. We were through in less than 20 minutes around 7pm. And EK flew out with a completely sold out A380!
As a friend who has more than a million QFF points (not all that unusual these days) said to me 'Qantas flights can often be late'.
In monitoring some (though not every) international flight departing from Sydney in particular but Melbourne to a lesser extent, it's noticeable how poor QFi's punctuality is compared to the likes of SQ, JL, NH, QR and so on.
Yet these other airlines are not based in Oz, so if anything, you'd expect them to be worse, because they may not have the amount of engineering expertise or other staff they'd have at their home base(s).
milehighclub's point about fewer departures in the early evening is valid, provided that aircraft in the morning at the times she mentioned have similar numbers of booked passengers to the early evening flights. However, unfortunately QFi's punctuality problem is not confined to the morning departures, but also evident with flights such as QF103, the 1925 hours SYD - HNL and others. Yesterday, QF139 from SYD to CHC, a B738 due out at 1925 did not take off until 2032, arriving CHC this morning 36 late at 0106 hours.
On Monday 9 May 2022, QF9 (1430 hours MEL - LHR via DRW) took off at 1547 with B789 VH-ZNG, so arrival in DRW should be 71 minutes late at 1921 hours. It may well pick up time en route to LHR as the schedules were given an extra half an hour despite the routing problem being for southeast bound flights ('the 2' and 'the 10') not the northwest bound ones (QF1/QF9).
QF43 today has B738 VH-XZH and is the 1625 hours - note, not a busy time at SYD for departures - from SYD up to DPS that took off at 1732, so expected gate arrival has become 2148 hours, 43 minutes behind.
