All,
If you work for BA the first place to look for any information is on the intranet.
I just read this thread, checked and found a detailed map and directions by public trnasport and car in less than one minute.
BA are going the way of making all information self help, hence the getting rid of 'answers' the old CC one stop shop.
log on at
my.baplc.com
It now has a great search engine supplied by google. I suggest you always look there first.
