I flew from HUY-SFB with Britannia on a B767-200ER a few years ago, we were one of the first flights with the 360 service. I got to say, it wasn't the best flight. First they messed up out seating... we paid £10 each to sit together, except if you were under 16 (which I was), then you didn't have to pay, so we arrived at the airport, got our boarding passes, my mum, dad and sister were in row 30, I was in row 4! Nice! The crew were helpful though and help resolve this problem, we did get our money back from Britannia.
Food was an average mush, the seat pitch was tiny, we tend to flew on schedualed airlines usually when goin to America.
The entertainment was the usual 14" TV's stuck everywhere. Bar service was complimentary, I think this was because it was a "special" flight though.
I got to mention though we had an awfully heavy landing in Shannon where we refueled.
