I flew in and out most days, the flight planning was just an extra hassle, but the two hour notice cost us quite a lot of work (most of our rotary ops involve a very short notice go, sometimes well under an hour for something like a Luton-Battersea)
Being told they had no knowledge of my flight plan on two seperate occasions, despite me quoting their clearance number and being told to remain outside was an utter pain. (one entry delay of 20 mins at £31 per minute)
Outside of working hours it was just very quiet flying, and once the controllers had started to get used to it, really rather easy.
However, the person in charge at DAP has not helped herself by refusing to talk to operators, and is now treated as something of a joke, and I'm ever so glad to have Farnborough Radar back.
