B789 VH-ZNM was the aircraft that yesterday on QF10 diverted to BLR for a medical. Subsequently, it took off at 0710 hours on Saturday 7 and flew to SIN, where it then formed QF210. This as airborne at 1956 hours, arriving PER on Sunday 8 at 0034 hours.
The plane has then been ferried from PER to SYD, arriving at 0757 this morning with its next duty being QF63, the 0930 hours SYD-JNB that took off at 1032 hours. FR24 incorrectly suggests it will arrive at the JNB gate at 1535, which would be early. FlightAware says '1705 hours' which is more realistic, and would be 55 minutes late.
QF1 (A388 VH-OQD) was in SIN on Sunday 8 from 0134 hours until takeoff at 0359 so LHR gate arrival should be about 1011 hours, 276 minutes late. From Sydney to London, this will be a net gain of 28 minutes on the complete timetable.
