JQ607 (Monday 3 July 1525 hours mid afternoon SYD - AVV that was in the sky at 1607, A320 VH-VQQ) should arrive at around 1733 hours, 33 late. This will delay JQ608 (1735 hours AVV back up to SYD) to about an 1805 hours departure.
Larger, 220 seat A321 VH-VWW on JQ411 (1320 hours early afternoon OOL - SYD that was not in the sky until 1534) should pull in to the mainland harbour city at approximately 1656 hours, 126 minutes late. It then formed the 1600 hours SYD down to MEL (JQ521) that was still in the queue on runway 34R at 1845, so it is expected at the arrival gate in MEL at about 2004 hours which would be 149 minutes behind schedule. This aircraft has been late all day: the rot commenced with JQ503 (0700 hours SYD - MEL) that did not take off until 0903 hours.
JQ519 (the 1751 hours pushback of the 1700 SYD down to MEL, A320 VH-VQW) should be at its allocated airport gate at 1913 hours, 38 minutes late.
Later on 3 July, JQ446 (2000 hours MEL - OOL that was not airborne until 2101, A320 VH-VFF) should arrive at 2301, 61 minutes late.
