On Sunday 17 December, QF12, the 1800 hours JFK - LAX departed at 1924. Arrival was at 2226 hours, 91 late, meaning that the different aircraft on QF12 to SYD departed 85 late at 2355 hours but is picking up a lot of time with Tuesday 19 arrival in SYD estimated at 0824 hours, six minutes early!
In contrast QF16 departed LAX 86 late at 0046 hours on Monday 18 December; BNE arrival (Tuesday 19) should be 50 late at 0805 hours.
Also on 17, QF10 (1155 hours ex LHR, A388 VH-OQH) did not depart until extremely late at 1735, 340 minutes tardy. The intermediate DXB stop was from 0430 hours on Monday 18 December (325 minutes late) to 0648 (343 late) so arrival in MEL is estimated at a shocking time on Tuesday 19, to wit 0307 hours, which would be 342 late. Often airlines manage to reduce the time at intermediate stops but not on this occasion.
This means that tonight's 2325 hours late night scheduled QF9 becomes an estimated 0500 hours departure on Tuesday 19, with the DXB stop projected from 1205 to 1400 hours and then LHR arrival at around 1815, 335 minutes late. In practice by recent observation it may be possible to pick up some of the deficit but as always 'it depends', and rarely do two days appear to be identical.
This is the worst timekeeping for QF10 observed for some weeks. It was because on 17 December, QF1 (A388 VH-OQA) arrived LHR slightly late at 0657, but sat in LHR all day, forming QF2 at night that took off at a delayed 2316, arriving DXB on Monday 18 (today) at 0926 hours, 91 minutes late. It is claimed to be departing DXB at 1130 hours, 115 late with Tuesday 19 SYD arrival projected as 0820 hours, 110 late.
The result was that VH-OQH arrived in LHR at 1403 hours (83 late) and then had the long turnaround described.
Tonight's (local time) Monday 18 December 2045 hours LHR - DXB QF2 is suggested as departing and arriving on time, but then being delayed - I'm guessing due to crew rest requirements - until 1415 hours in DXB on Tuesday for SYD arrival at 1105 hours on Wednesday 20, 275 minutes tardy.
The Tuesday 19 December QF2 ex LHR should in theory be unaffected but that will alter if tonight's QF10 to QF9 turnaround in MEL is significantly slower than assumed, or if time is lost re gate ex MEL to arrival at gate in LHR for QF9.
So the Christmas holiday 'fun' has begun for long distance QF passengers.
