The problem with Norwich is that they don't understand the concept of private flights.
Last summer I had the pleasure of flying with Grainger in a Jetranger from Norwich. His helicopter, his passenger.
"Can I see your boarding pass please madam! (Sadly I am no longer of an age where I get called "Miss"). "I don't have one, it's a private flight". "Can't go through without a boarding pass". "It's a private flight" etc etc.
So for anyone coming into Norwich, try to get Sterling to carry out the handling - it'll be much more simple!
