Hi there,
Just thought I'd post a little reply to this one. I work for TUI, the company which now owns the Thomson Travel Group and hence Britannia. I have travelled with Britannia on numerous occasions over the past year and six times since 11/09/01. Each and every time I have asked for a visit to the flight deck and the response has been none other than, "Are you kidding??" I am not sure about other airlines, but Britannia wouldn't even let a 5 year old kid in the flight deck when I was on the aircraft. So in response, I do not think that flight deck visits will start again, or not at least until security is at an absolute maximum. It is a shame, because I always sat in for the landing with Britannia (even though they are not supposed to allow it ;-) ), but I guess never again.
Cheers
Ross
