Maybe there isn't any? I have wanting to do some Concorde flights, and considering the B.A. Around the World Tour from 1999, as I just watched a DVD about it.
I did a forum search and saw a couple posts from years ago indicating there were some flights in both the Bid and Scheduled Divisions, but I can't seem to find any. With the recent Concorde release for FSX I would have thought others would like to fly some routes as well. Thanks.
