Later on Sunday 1 March, QF45, the 1730- hours MEL - DPS B738 VH-XZD departed 17 minutes behind schedule but did not take off until 1826, a very long period of 39 minutes from pushback to lift off. Arrival is a predicted 2120 hours, 50 minutes late.
QF95 (the B789 due to depart MEL at 2220 hours) should instead do so at 0045 on Monday 2 March, 145 late with SFO arrival estimated as 1935 hours, 115 minutes behind the timetable. Although on Saturday 29 February, QF10 departed LHRtwo minutes early at 1153, arriving PER today at 1249 hours, 19 minutes late, it did not depart the latter until 1705 this afternoon, 185 minutes tardy. Hence MEL suggested arrival is 2325 hours late this evening, three hours late.
As a side issue on Friday 28, QF10 pushed back in LHR at 1324, 89 late with eventual MEL arrival last night (Saturday 1) at 2137 hours, 72 minutes behind the timetable.
QF10 has usually been punctual or close to it since its introduction, and has yet to be diverted IIRC (although as others have remarked, due to winds, the northbound ex PER QF9 is the more likely candidate for this.)
