Charlie, I think you may well find the answers you are looking for at the Flyer show on Saturday. I Would head straight for the BA stand and ask those manning it when the next course may be. Head straight there because it most probably will be rammed, with a several people waiting to speak to the staff. A very useful one stop shop event to gather lots of info and news, before heading home to slowly and carefully digest!
P.s bring your own lunch. It's crazy expensive for the Sofitel lunch.
