What airport specifically are you departing from, and do you only want BA or any airline?
Glasgow and Edinburgh are the best options for me however was quite prepared to try ex INV but doesn't seem to be saving anything ( I may be doing something stupid though).
Would rather fly BA. Used to fly solely United or Delta but a couple of bad experiences have led me back to a British carrier. Don't dislike Air Lingus but the lack of tier points would bother me.
