Not sure if it's related to the storm passing over or very close to Sydney, but on Friday 26 May 2023, QF81, the 1150 hours SYD-SIN (A332 VH-EBP) is not expected to push back until 1430 mid afternoon. This delay is unusual as 'the 81' is one of the more punctual QFi offerings. The aircraft had arrived as QF68 from BLR at 0910 this morning, an amazing 55 minutes early so the winds may have been favourable.
EBQ is on QF67, the 0905 hours SYD-BLR airborne at 0953 midmorning, so gate arrival should be at around 1706 hours, 46 behind with presumably unfavourable winds not assisting.
EBS arrived in SYD this morning at 0618, seven minute early as redeye QF82 from SIN. It has then operated empty to BNE, becoming airborne at 1114 hours and arriving not long ago at 1231. It is forming a much delayed QF51 (normally a punctual runner) that is estimated to depart BNE at about 1330 (optimistic!) for SIN.
Given this late operation of the SYD and BNE A332 flights to Singapore today, at least one departure tonight is likely to be tardy, given as dajop reminds us, one aircraft typically overnights at the latter.
The B789 on the 0940 hours SYD-JNB is not predicted to push back until 1300 hours, so we can back it in QF64 tonight ex JNB will be baldy late.
B789 VH-ZNB on the 1245 hours QF21 MEL-DFW long flight is predicted to depart almost an hour behind schedule.
