That extra 'padding' causes lots of problems on a good day, when everything is running ontime, as stands are allocated on STD, so if you arrive early, there might not be a parking stand available, so you end up ground holding, which is frustrating for the pax onboard, (and the flight crews, as they never understand and are always shouting over the r/t into the ops office 'that we have had X hours to arrange a stand for them'
I always feel sorry for SAA, as when they arrive at LHR, they have to wait for either Bmi or BA to clear the stands with their early departures before they get a parking bay. Holding for 40mins is not uncommon for them, and it's the same every day.
I personaly think that all airlines should base their statistics on ARR times rather than DEP times, as has been said, you can leave A 1hour late and still arrive at B ontime, and that is why everyone is one the plane in the first place - to get to B, so whats it matter what time you leave A as long as you are in B ontime ???
- anyone work for IATA want to change the rules....
