On Wednesday 28 April 2021, JQ731 (A320 VH-VFK, the 0700 hours early morning from MEL down to LST) did not become airborne until 1128 hours, so arrival was at 1218 hours, 253 minutes behind schedule. The return flight JQ730, the 0845 hours, was at the JQd equivalent of a 'gate' at 1348 in MEL, 238 late, while its next flight was not until 1520 hours (JQ518, MEL- SYD) so that should arrive a few minutes early, showing how airlines can recover time with longer than minimum turnarounds.
JQ774 (1020 hours MEL - ADL) had VH-VFO, taking off at 1110 and arriving at 1146, 31 minutes tardy.
JQ515 (1230 hours lunchtime SYD - MEL) got the boot.
