Qantas Delays/Cancellations

[Melburnian1]

I’m at MEL currently and QF35 MEL-SIN (VH-OQL A388) scheduled for 1155 departure taxied out about 15 minutes ago and did a loop before returning to the gate

While aircraft transponders may be blocked by buildings and hence not all show up on sites like FR24, QF35 is not visible. May not be a good sign.

While aircraft transponders may be blocked by buildings and hence not all show up on sites like FR24, QF35 is not visible. May not be a good sign.

I’m in the VA lounge and could see the tail of it coming in and then it disappeared off the FR24 radar shortly after

QF35 (1155 hours scheduled ex MEL) on Monday 22 April (as jase05 indicated, A388 VH-OQL) took off at 1405 with SIN arrival likely at 1958 hours tonight, 123 minutes late. So at least it wasn't cancelled. Tonight's QF36, the 2015 hours redeye from SIN down to MEL will be delayed until about 2140 in its pushback. In turn, there's a good chance Tuesday 23 April's QF93 from MEL to LAX will be slightly delayed at a minimum.

The 1210 hours SYD - MNL (QF19) pushed back 42 late with arrival suggested as 45 late at 1915 hours. This will delay QF20's departure by at least 35 minutes.

Saturday 20 April's QF10 departed LHR at 1459 hours, 169 late, arriving PER on Easter Sunday (21) at 1448, 173 late. It then pushed back at 1612 hours, 167 late with MEL arrival occurring at 2138, 163 late for B789 VH-ZNF. This aircraft is proceeding to SFO on the QF49 that is expected to depart by QF two hours late at 2255. SFO arrival is predicted (same day) at 2000.

As QF50 is then due off blocks at SFO at 2100 hours on Sunday 21, expect it to be at least slightly delayed. Too early yet to make a prediction that's remotely accurate as it depends on QF49's running...

QF49 arrived SFO at 2006 hours on Sunday 21 April, 111 late after departing MEL at 2306, 131 late. The aircraft 'reversed' and formed QF50, departing only 37 late at 2137 hours, with Tuesday 23 arrival in MEL forecast as just 12 late at 0542.

Although QF12 from JFK to LAX was punctual on Easter Sunday (21 April), QF94 pushed back in LAX at 0048 on Monday 22, 128 late. Arrival should be on Tuesday 23 at 0855, 85 late. Due to the generous turnaround for QF94 to SIN-bound QF35, the latter - in theory - ought not be adversely affected timewise (although today - Monday - it was late).

 

[Melburnian1]

Also on Sunday 22, A333 VH-QPJ on QF19 from SYD to MNL departed 42 late at 1252 hours, arriving 44 late at 1914 hours. This will delay QF20 to approximately pushback at 2025, 25 late.

Re: QF9 MEL - DXB - LHR delayed 16 hours



Tightly rostered??? Qantas normally have a spare aircraft sitting in Sydney, its crewing that is more of a constraint at times than aircraft. FWIW I don't believe local passengers get taxi vouchers.

Local pax can get taxi vouchers. Even a airport hotel. Just say unable to go home as the house has been holiday let

Saturday 20 April's QF10 departed LHR at 1459 hours, 169 late, arriving PER on Easter Sunday (21) at 1448, 173 late. It then pushed back at 1612 hours, 167 late with MEL arrival occurring at 2138, 163 late for B789 VH-ZNF. This aircraft is proceeding to SFO on the QF49 that is expected to depart by QF two hours late at 2255. SFO arrival is predicted (same day) at 2000.

'The 49' has to my mind a great schedule for leisure, VFR (and many business) travellers, as the evening arrival means one can check straight into an hotel and after a suitable walk around and bite to eat, retire for the night. I'm in the Drron camp of detesting super early morning air arrivals. Not all businessmen and women will share my view but I often wonder how well they can really cope with appointments starting at say 0930 hours after such a massive time change (admittedly even worse travelling east) and difficulty of sleeping on a plane whatever the configuration and class. It just isn't as comfortable/ comforting as a twinette or roomette sleeping berth on a train.

Any early morning arrivals usually mean that cabin lights are turned on up to 2 hours prior to arrival. If arrival is 0530, potentially the passengers are woken at 0330 or 0400. Hard to see how this is conducive to high cognitive functioning

 

[Melburnian1]

As QF35 was delayed, the Monday 22 April QF36 departed SIN at 2119 hours, 64 late. MEL Tuesday 23 arrival is estimated as 0653 hours, 78 late, so in theory QF93 to LAX should be on time ex MEL.

 

[Melburnian1]

On Tuesday 23 April 2019, QF824, the morning 0840 hours nicley timed BNE - DRW took off at 0918. B738 VH-XZN should arrive at 1305 hours, 35 late.

 

[Melburnian1]

A333 VH-QPA on QF19 (1210 hours SYD - MNL, Wednesday 24 April 2019) took off at 1303 with arrival expected half an hour late at 1900 hours. This will delay pushback of QF20 (the redeye back down to SYD) to a predicted 2015, at least.

Earlier, the MEL up to NRT QF79 departed an hour late at 1010 hours, so suggested arrival is 1932, 57 late. Tonight's NRT - BNE redeye (QF62) is displaying as an estimated 50 late pushback at 2045 hours. QF79 and QF61 can either 'form themselves' or each other's southbounds - QF80 and QF62. The roster varies. It may be a way sometimes of allowing an A333 to have maintenance in BNE without having to run empty - 'ferry' - from MEL.

QF9, the Wednesday 24 scheduled mid afternoon 1515 hours MEL - LHR via PER has unusually been delayed to a projected 1645, meaning the PER stop changes to 1835 hours (80 late) to then depart at 2000 (75 down) with Thursday 25 arrival in LHR at a suggested 0625 hours, 80 late.

Calling milehighclub, who in her usual informed way may know whether it's a MEL issue (equipment not the airport acronym) delaying the B789. More time though for drinkies in the lounge. One would expect fairly often there'd be an AFFer on this flight, whether travelling internationally or as some do to sample it, domestically.

 

[Melburnian1]

The expected delay to QF9 ex MEL on Wednesday 24 April has blown out to displaying as 1755 hours (160 minutes late) but that was a few minutes ago. One good thing is that the crew waiting in PER (I assume it's not the same one MEL - PER - LHR) would have a few hours' notice so they wouldn't have to sign on too early, thus reducing the chances of the long PER - LHR sector being cancelled due to staff being above permitted hours (which jb747 has said are 18 if I recall, but extendable to 20 with agreement).

At this stage, expected LHR arrival is 0735, 150 minutes late on Thursday 24 but I'd suggest it will be beyond that.

Does anyone have a window into why it's delayed? It's usually pretty punctual, and has only rarely been cancelled.

UPDATE: QF9 departed MEL at 1800 (165 minutes late), taking off at 1819 hours with the newest B789, VH-ZNH. The pER stop is displaying as 1955 to 2110: normally this takes 90 minutes , not 75. The faster I can recall is about 80 - 85, given that not just luggage but freight has to be unloaded/loaded.

Is the catering for the long sector all loaded in PER or does some of it come from MEL?

QF28 from SCL to SYD (B744 VH-OEG) is arriving at about 1827 hours, 37 minutes tardy.

FURTHER UPDATE: 'The 9' arrived PER at gate at 1949 hours, 154 minutes late.

 

[Melburnian1]

In further on Wednesday 24 April, QF117, the mid evening (recently rescheduled from an afternoon departure) SYD - HKG is predicted to depart shortly, 70 late, meaning arrival on Anzac Day at 0615, 75 late according to QF, although recently this flight has picked up time on a gate-to-gate basis. On six of its last seven trips, it arrived HKG at gate between 15 and 36 early.

 

[Melburnian1]

The tardy QF9 departed PER on Wednesday 24 April at 2118 (153 late), taking off 16 minutes later with Thursday 25 LHR arrival tipped as 0755, 170 late.

Thanks to yesterday's delayed MEL - NRT QF79 that formed QF62, the latter was blocks off in NRT at 2047, 52 late, arriving BNE on Thursday at 0629, 34 late.

A332 VH-EBN arrived in PER on 24 April at 2247, eight minutes early on QF583 ex SYD but then lost time on the redeye (QF568) back overnight to SYD, arriving at 0641 on Anzac Day, 36 late. It then must have had to substitute for another aircraft as it is currently on QF565, the 0620 hours early morning SYD back to PER that did not take off until 0735 or become airborne until 0749. Consequently expected PER arrival is 1014 hours, 49 late. At this stage it looks to be forming QF642, the 1025 hours PER back eastwards to SYD, so if the case, that flight will be at least 45 late off blocks.

 

[Melburnian1]

In further on Anzac Day (25 April 2019), QF19, the 1210 hours SYD - MNL is expected to push back at 1500 hours mid afternoon (170 late) with slated arrival at 2105 mid evening, 155 late. This will delay departure of the redeye QF20 back down to SYD until at least 2215, 135 minutes tardy. The QF website is displaying '2140' as the QF20 expected pushback but a 35 minute turnaround is impossible for this size aircraft.

QF43 (mostly now an A332 as is the case rostered for today, but occasionally an A333), the 1630 hours SYD - DPS is forecast to push back two hours late with arrival at 2300 tonight, 115 late. This will delay tonight's redeye, QF44. These flights are usually good timewise.

UPDATE: QF19 ex SYD has been further delayed to 1530 hours, but that time was 15 minutes ago.

 

[Melburnian1]

On Thursday 25 April, the delayed QF19 arrived MNL at 2201 hours, 211 minutes late and in a coincidence, departed back down to SYD at 2331, also 211 late. On Friday 26 it should arrive at 0913, 183 minutes behind schedule. The aircraft, A332 VH-EBO, is then forming the longer flight of QF23, the 0950 hours midmorning SYD to BKK that is predicted to push back at 1035 hours with a minimum turnaround in SYD. Too bad if one wants a clean tray table.

Thursday's QF43 was later than predicted above, pushing back in SYD at 1909 hours, 159 late with DPS at gate arrival 2327 hours, 142 minutes behind. 'The 44' then departed DPS at 0033 on Friday (128 late) with SYD arrival becoming 0805 hours, 100 late.

The 0725 hours SYD down to WGA, QF2221, is expected to depart an hour behind schedule.

QF575 (0825 hours SYD - PER) should depart at 0900.

Later this afternoon, QF449, the 1630 hours SYD - MEL has been cancelled.

 

[Melburnian1]

With the delayed QF20 arriving at 0915 in SYD (185 late), QF23 on Friday 26 April did not achieve minimum turnaround time as hoped. It was off blocks 64 late at 1054 so BKK arrival is predicted as 1747, 67 late. Often this flight makes up time, but it did not take off until 1115 hours.

The 0935 hours morning BNE - NRT, QF61, departed half an hour late with arrival forecast as 1829, 34 late.

 

[Melburnian1]

In more on Friday 26 April, QF27, the timetabled 1235 hours B744 from SYD across to SCL has been delayed to an expected 1400 in its pushback. This gives travellers on today's QF28 (SCL - SYD) plenty of notice to expect a late departure in many hours' time.

UPDATE: Departure was 99 minutes late at 1414 with SCL arrival predicted same day at 1225 hours, 80 late. Aircraft is B744 VH-OJU.

It’s 0223hrs at LAX with humidity 95% temp 14C and no wind. Misty and low visibility ceiling.

Hopefully won’t impact the morning arrivals.

 

[Melburnian1]

From previous advice there needs to be a barometer that's dropping to create fog, as well as the two preconditions you outlined. But I'll leave such to experts.

 

[Quickstatus]

The relationship between barometric pressure and fog formation is not straightforward. Actually the falling temperature is of prime importance in the setting where the vapour pressure of water is greater than the saturation vapour pressure with calm winds and high humidity (water content in air).

(A lowering of barometric pressure is often associated with a falling temperature).

But for what its worth, currently the barometric pressure is normal at 760mmHg.
