Very sorry to hear that Britannia "weren't interested in a visit". We are well aware of the significant numbers of our passengers, from all walks of life, who would be intersted in a look and chat up front. Most of us do our very best to allow as many as possible to do so, but are also aware that our cabin crew are required to work almost non-stop throughout a short European sector. Having passengers moving around in the cabin makes their life considerably more difficult for them and maybe it's just possible that some requests to visit the flight deck get "overlooked".
If you fly with us again do please emphasise that you work in ATC (or better still, write a brief note addressed to the captain) and I feel sure you will receive a very warm welcome. I personally feel that any opportunity for pilots and ATC to chat together is worth its weight in gold.
Apologies for this particular instance.
