It was the SYD end i was wondering about - I thought relevant to this thread as can predict delay(s) knowing the inbound/operating aircraft. I’ve noted some have come in from SFO arriving early morning so long turn if that’s the case.docjames, perhaps not a question for this thread, but if I understand it, QF3/QF4 are B744s with the schedule showing an arrival in HNL at 0830 and a departure at 1050 hours local time on MWFSa (i.e. four days a week at present).
The allowed turnaround time is greater than the minimum observed that for an aircraft of this size is normally about 100 minutes. It always strikes me as sensible, when feasible, for turnarounds at outstations to incorporate more time than really needed as this advantages boarding passengers if an inbound is late. QF doens't have the option at HNL to substitute another another as it may in SYD, for example.
docjames, of the last three ex SYD as QF3, two were formed by (as you suggest) QF74 ex SFO and one by QF26 ex HND, so in all three cases, the aircraft spent 10 - 12 hours in SYD.It was the SYD end i was wondering about - I thought relevant to this thread as can predict delay(s) knowing the inbound/operating aircraft.

VH-OQF on 'the 94' is now predicted to arrive at 1932 hours on Friday 14 June in MEL. The expected delay to QF93 (0900 hours MEL - LAX) has turned into a 2115 hours pushback, 735 late. Same day LAX arrival should be 1845 instead of 0625 hours, so 740 late. This should not adversely affect timekeeping of the Friday 14 late evening QF94 ex LAX.QF93, the 0900 hours Friday 14 June MEL - LAX A388 is not expected to depart until tonight at 2050 with predicted arrival at 1820 instead of 0615 hours, 725 minutes late. While there are three overnight (redeyes) from LAX to JFK operated by AA, I wonder if some passengers ask for an hotel overnight in LAX (or pay for one themselves) and travel to JFK the next day on either QF's B789 or an AA flight?
This looks to be due to QF94 (A388 VH-OQF), the Wednesday 12 June 2240 hours LAX - MEL not departing until 1007 hours on Thursday 13 with arrival in MEL tonight at a suggested 1905 hours, 695 late...
QF94 arrived at 1919 hours on 14 June, 709 minutes late.VH-OQF on 'the 94' is now predicted to arrive at 1932 hours on Friday 14 June in MEL.

QF708, the 14 June 1610 hours ADL across to CBR took off at 1703 so arrival should be 1855 hours, 40 late for VH-VZU.
At least VH-OQE completed its planned maintenance by Elbe Flugzeugwerke (Not Lufthansa Teknik) at DRS and departed the workshop approximately as VH-OQG entered. The OQE maintenance took approx 2 weeks. Is OQG going to be the same?The other unfortunate aspect of two A388s unavailable means less time for what may be necessary maintenance in LAX. This must eventually have some consequences for timekeeping as it'd be logical that some maintenance cannot be deferred ad infinitum.
Also SYD - SFOFortunately the ageing, fuel guzzling and dated in cabin design and fitout (but still 'Queen of the Skies') B744s are not heavily utilised now, as (unless I've omitted something), the seven remaining only operate SYD to HND (daily), HNL (MWFSa only). JNB (six days a week, W excepted) and SCL (SuWF only, but has been more frequent in some recent weeks.) Availability of spares varies but there's usually at least one spare in Sydney.
jb747 informed us quite a while back that these bookings were made many, many months in advance. I can't recall his exact words but he may have suggested 'more than 12 months' ahead....It is my understanding that MRO slots are planned and booked in advance and even if an aircraft could do their checks 1 or 2 weeks later, they may not be able to because a spare slot accommodating the delay may not be available.
QF12 arrived in SYD on Saturday 15 at 1720 hours.Saturday 15 June 2019 will see QF7, the lunchtime 1235 hours A388 for the long flight from SYD to DFW delayed until a predicted 1910 in its departure. Same day arrival should be 1850 hours, 350 minutes late.
This is due to the Thursday 13 June's QF12, the 2230 hours scheduled ex LAX not departing until 0903 on Friday 14 so Saturday 15 SYD arrival is forecast as 1715 hours, 645 minutes tardy...
