Continuing with Friday 4 May 2018, QF580, the 1230 hours lunchtime from PER across to SYD that was in the sky at 1336 hours (A332 VH-EBL) should arrive at 1915 hours, 40 minutes tardy.
QF626 (1610 hours from MEL up to BNE that was up up and away at 1659 with the usual B738, in this case VH-VZO, should arrive at 1852 hours, 32 minutes late.
QF463 (1830 hours SYD - MEL, A332 VH-EBD) took off at 1917 so a 35 minute tardy arrival at 1940 is expected.
The 1800 hours MEL up to SYD, QF458 was airborne at 1902 with B738 VH-XZM. Its arrival is estimated at 2005, 40 minutes down. Just ahead is QF496, the scheduled 1745 hours that took off at 1901 with VH-VZL: it should pull in to an allocated gate at roughly 2002 hours, 52 late.
QF766, the 1725 hours ADL - SYD took off at 1822. VH-VXR should be at its destination gate at approximately 2023 hours, 38 minutes late.
The 1805 hours MEL - CBR, QF2132 (Q400 VH-LQB) is worse with takeoff at 1923 tonight meaning arrival at 2015 hours, an hour behind schedule. Another aircraft must have failed because this one only arrived in MEL from CBR at 1828, which would not be the normal roster (arriving 23 minutes after a flight was due out.) FR24 records are incomplete.
QF462 (1900 hours MEL up to SYD that took off at 1946, B738 VH-VXK) should arrive at roughly 2056, 31 minutes late.
