Friday 18 May 2018 has QF12, the transcon from JFK across to LAX having taken from 1901 hours (51 minutes late) to 2154 (54 minutes tardy) to cross that nation. The connecting QF12 then departed LAX a similar 55 late at 2325 meaning Sunday morning 20 May should see the arrival at 0721, 51 late again.
'The 16' is not expected to depart LAX until 0200 hours this morning local time for a BNE arrival at 0850 tomorrow (Sunday 20), 165 late. If so, this will delay tomorrow morning's BNE - LAX B744, QF15.
QF8 is rarely delayed but on Fridy 18 it commenced pushing back in DFW at 2218, 28 late; on Sunday 20, it should have passengers ready to alight at roughly 0754 hours, 49 minutes behind schedule.
Today (Saturday 19) QF63 departed SYD at 1219, 84 minutes tardy for a projected JNB arrival at 1740 hours, 40 late. This will delay the overnight QF64 in its departure at least a little but it often picks up time on the schedule.
