Also on Tuesday 27 October, A332 VH-EBK ex SIN (Monday 26) as QF52 arrived in BNE at 0541 hours, 14 minutes early. It then operated domestic flight QF519, the 0910 hours that arrived SYD at 1148, three minutes late.
It then transferred to the SYD international terminal and is on QF41, the usually punctual 1425 hours SYD-CGK that was up up and away at 1524. This means expected gate arrival in Jakarta at 1858, 58 minutes late, delaying the return redeye QF42, the 1950 hours likely to depart at least 35 late.
Presumably these domestic to international transfers of aircraft are unavoidable - the base is in SYD, not BNE or MEL - but they add a level of complexity and often cause compounding delays.
