Sydney has had storms on the afternoon of Monday 25 November so it's not surprising that there's quite a deal of late running, with VA862 (1630 hours SYD down to MEL) not airborne until 1711 hours. B738 VH-YFZ should arrive at 1835 in the early evening, half an hour behind.
VH-YIW is on VA144, the timetabled 1600 hours AKL - SYD up up and away at 1639, about 20 late. It has held offshore, so at gate arrival is nominally showing as 1813, 33 late.
VA1179 (1630 hours ABX up to SYD in the sky at 1650, only 10 minutes late) has ATR 72 VH-FVP with estimated arrival 1839, 44 late as at 1813, the aircraft was holding north of scenic Wombeyan Caves.
VH-YIH is the 1630 hours MEL - SYD airborne punctually to 1642, but then the music stopped with a lengthy hold above Marulan. It is displaying an expected at gate arrival of 1855, an hour late.
