Keep a close eye on your booking - a delay of that magnitude for QF 15 may well see the LAX-JFK-LAX sectors for that aircraft cancelled and pax rebooked on AA.
An accurate prediction - it has come to pass.
Also on Wednesday 22 March 2017, QF453 (the 1700 hours SYD down to MEL that took off at 1817) should arrive at about 1934, 59 minutes behind. Aircraft is B738 VH-VYL.
The 1730 hours MEL - SYD (QF454) took off at a much delayed 1859, so arrival of A332 VH-EBR is unlikely prior to 2004 hours, 69 minutes late. As a result, QF583, the 1955 hours SYD - PER is predicted to depart about 70 minutes late.
SYD has been wet this afternoon with storms north of it at 2000 hours looking ominous and up to 30,000 residents without power for what is said to be 24 hours. There have been quite a few QF cancellations including QF1483, the 1630 hours SYD - CBR; QF2217, the 1855 hours to ABX and QF2178, the 1900 hours SYD - PQQ.
QF451 (1715 hours SYD down to MEL) took off at 1956 (A333 VH-QPC, relatively rare usage of this QFi aircraft on this domestic sector) with expected arrival at 2100, 130 minutes tardy. It had earlier arrived from PEK as QF108 at about 1735, 160 minutes tardy.
VH-QPC is next rostered on the Thursday 23 March QF412, the 0730 hours MEL - SYD. This appears to be poor utilisation for this in-demand refurbished QFi plane but the bad weather in SYD may have meant no other suitable aircraft was available for QF451, as like most transport operators airlines try to avoid using an aircraft on a flight that is not arriving until after the second flight is timetabled to depart.
Concurrently with VH-QPC operating southbound, stablemate VH-QPA is working northbound on QF6156 from MEL to SYD that should arrive at about 2115.
QF28, the SCL - SYD long haul (B744 VH-OEF) most unusually had to divert to MEL, arriving at about 1815 hours. At 1957 it took off from MEL. SYD arrival is predicted at about 2106 which is 201 minutes later than the timetabled 1745. One assumes this was due to bad weather in SYD. I cannot previously recall QF28 having diverted to MEL. As a flow-on, QF25, the 2135 hours SYD - HND is expected to depart at 2230 which may be a little optimistic: 2250 would be more likely.
Often QF25 gains on the timetable on a gate-to-gate basis so arrival in HND may only be 45 minutes late tomorrow morning (Thursday 23.)
QF463 (1830 hours SYD down to MEL that took off at 2004 hours, B738 VH-VXM) should arrive at around the 2113 mark, 68 minutes behind schedule. QF479, the following departure due out at 1845 (VH-VXF) took off at 2009 so a 2123 hours arrival is predicted, 63 late.
The 1805 hours BNE - SYD (QF563) took off at 1859 with B738 VH-VYD, so the 2113 hours predicted arrival will be 33 minutes late.
