I was wondering why QF 27 never seems to take off on time? Has anyone got an explanation for this ? Thanks
From the logs:
11/6 - gate departure 7 minutes late, 10 minute taxi
11/8 - gate departure 3 minutes late, 23 minute taxi
11/9 - gate departure 27 minutes late, 10 minute taxi
11/11 - gate departure 14 minutes late, 16 minute taxi
11/13 - gate departure 50 minutes late, 23 minute taxi
11/15 - gate departure 13 minutes late, 15 minute taxi
11/16 - gate departure 17 minutes late, 13 minute taxi
11/17 - gate departure 29 minutes late, 26 minute taxi
Not terribly late departing the gate and not terrible taxi times, but added together it can seem rather large.
The scheduled times you are seeing is gate departure times, and the actual times are runway departure.
Outside of that, there is no insight as to what causes these delays.
