Longer taxi times
These gates (A3/A5) could not be further from the runway. I just tracked BA1385's taxi this morning from gate to 23L threshold and it was 18 minutes (05:58>06:16)!
Quick distance check:
From Gate 142 (T3) it's 1.7km to 23L threshold
From A3/A5 (T2) it's 3.1km to 23L threshold
Approaching double the taxi distance/time.
Surely this has to have an impact on timetables and turnaround times for BA?
