Also on Wednesday 9 March, QF9 (VH-ZNJ) took off from MEL at 1841, 26 minutes after the retimed (slowed) scheduled pushback, with DRW arrival becoming 2156, 61 minutes tardy. The second sector was airborne at 2332, arriving LHR on Thursday 10 at 0744, 54 minutes late, and notably unusually ahead of QF1 (see above).
Given the small size of the DRW lounge, it would have been challenging to have two groups of eligible passengers concurrently present.
QF8 (9 March, the 2020 hours mid evening DFW - SYD) was in the sky at 2147 with B789 VH-ZNK, so SYD arrival on Friday 11 should be at about 0735 hours, 90 minutes tardy.
The SYD - JNB flights have all been punctual or close to that when occasionally monitored, but the 9 March one with VH-ZNI (the 1015 hours) took off at 1207, arriving in the South African major city at 1632, 77 minutes behind its timing. Returning, the 1715 hours scheduled pushback became takeoff at 1822 hours, arriving SYD today (10 March) at 1446 hours, 46 minutes late.
