All the sky blue aircraft got airborne first that night..........and that is wrong
Well I find this very hard to believe. In 13 years of working out of Schiphol (and driving one of those sky blue aircraft) I have never once seen any favouritism dished out by ATC when it comes to start sequences etc. Maybe it looks it because there are so many KLM aircraft all calling for start at the same time (we have a seven wave system- inbound and outbound peaks according to the time of the day).
Now Brussels Airport was a different matter when Sabena were in existance- they had their own taxiways to overtake all the visitors!
But we use the Polderbaan (36L/18R) as much as anyone- as someone said, it depends on where you are going. Polderbaan for westerly departures, Zwanenburgbaan (36C/18C) for the easterlies. Alternatively, it is 24 (Kaagbaan) for westerlies or 18R (Aalsmeerbaan) for easterlies and occasional alternative combinations depending on the wind or current noise complaints from the neighbours.
