Since an ATCO started all this can i turn the discussion around a little. When i am sat at MAN about to launch for LHR with a slot delay on the ground why is it not possible for either...
ATC to give me an accurate prediction of the delays at LHR
Or, preferably, a slot at BNN to make to minimise the holding.
We have the technology to arrive at a given point at a prescribed time....
It seems ridiculous that a 30 min flight can experience 20 min delays on arrival. Particularly after being given a departure slot.
