What do you mean by scheduled time? The times in the schedules are the times the flight aims to leave the gate, not the runway time. Obviously, airfield delays affect both -- but the latter are much less controllable by an airline. Are you saying that VS are more likely to have longer airfield delays than the average because of a lack of clout? I would be interested to see some data to support this!
So are you saying if the flight leaves the gate on time but stands on the runway for a hour it is not a delayed flight,I was in no way knocking virgin (other sites make a good job of that)as we have flown with them for years, and apart from a 24 hour delay on a MCO flight home have no problems with them,but just made the point that there always seem a delay on the flights that we have taken be it 10 mins or 1 hour,and if you read my orignal post it said "was told that they did not have the clout of the major airline BA,AA"
As far as I'm aware airlines measure there OTP in two ways. Exactly on time and within 15 mins of STD. The Scheduled time as mentioned above is the time of pushback. If the flight encounters airfield delays then as long as it has pushed back on time it is classed as an on time departure. Most airlines anticipate slight airfield delays and incorporate them into their schedules.
A good example of this is JFK to LHR. we all know that around the VS4 and VS46 departure times departure delays can be excessive.
Looking at the block times (push back till chocks on at gate) for the three VS flights:
VS4 7.20
VS46 7.20
VS10 6.50
VS as do most other airlines 'pad' their schedules to allow for these delays. Therefor VS add taxi ing time to the VS4 and 46 to make up fr the anticipated delays on departure at JFK. This helps maintain schedules and although we may trundle around the taxi ways at JFK for what seems like an age, whenever I operate the 4 or 46 we normally arrive on time.
Maybe I've went off on a tangent but yes, if you push back on time then it's classed as an on time departure.
Pheew!
