dicegirl,
Just a bit of extra information to add to c.r.m.'s excellent directions, the double doors will be labeled Concorde House. Although this is in the South Terminal, the buses will stop at Hangar 6 if you ask. The buses will be marked X,Y,Z and X overflow car park or something similar. The only thing I will say is that the drivers can sometimes be funny about taking people without ID's, which of course you won't have to start with, so make sure you've got something, ie a headed letter, with proof of training on it close to hand. This should be fine for them. Enjoy your course, study hard and we look forward to seeing you on line.

P.S. For the record, LGW fleet is part of BA mainline in case you're wondering.
