It appears FJ910 SYD-NAN is routinely ~ 1 hour late.It was 55 minutes late on 12/12 when we were on it.Aircraft was at the gate early,boarded a little late the sat on the plane for 45 minutes before taking off at 1405.
Our son and his family had exactly the same experience 21/12.
We had been watching the arrival time for the flight from 16/12 to 20/12 when we were staying at Momi Bay as it's flight path had it flying past our bure on descent into NAN.However arrival time on those days was between 2014 and 2027 being after dark.
