Yes, I too received the e mail from them, and I for one am absolutely delighted at this re-think by BA, and if it helps their cause by relating it to or blaming it on recent security matters, then frankly I don't really care! Well done BA and many thanks for reverting back to the two pcs of luggage (for the US) of 32kg - (Mrs R is particularly pleased!!)
Thank you and kind regards
