On Tuesday 11 December 2018, GS7939 from CGO down to SYD (A332 B-8959) should arrive at 1416 hours, 161 minutes late as it only took off at 0047 against a timetabled 10 December mid evening departure of 2125 hours.
Thankfully, GS7940 is not due to depart SYD this afternoon until 1335 so it should be able to be off blocks at about 1530 if all goes well, 115 minutes late. Not ideal, but better than 161 late, again showing how if feasible (slot availability, crew and aircraft utilisation requirements, connections) it is better if international airlines can build in some padding to the turnaround times.
