On Friday 30 October, QF127, the 1115 hours SYD-HKG (A333 VH-QPA, class leader) took off at 1239. Expected gate arrival becomes 1835 hours, 45 minutes late.
Sister -QPB is on QF29, the 1105 MEL-HKG airborne at 1228. It should arrive at gate at about 1815, 40 late.
B789 VH_ZNG on the LHR down to PER QF10 is arriving at 1250, 35 behind, making it challenging for the 1400 hours second sector to MEL to punctually depart. In turn this may delay the 2245 hours QF93 from MEL to LAX that with the recent timetable changes is usually the same B787-900.
