I disagree Jerry.
I actually learnt to fly at Cardiff 36 years ago and understand the problems. There is nothing conveniant about flying long haul from Cardiff or Norwich via Schipol as this usually involves a long layover. Heathrow is more convenient to both the above local airports to fly direct long haul and much cheaper. Cardiff and Norwich both suffer from a low catchment area.
I guess you have never had the misfortune to be stuck in Amsterdam after a long haul flight when the regional connection is cancelled.
It happens on a regular basis.
Nothing can beat Heathrow for cost and destination.
As for KLM long haul...I guess you don't travel to Asia much.
