I flew nonstop London to Denver with BA 6 years ago, and it remains to be the gold standard of flying and customer service to me. They make you feel like a human being (which is wonderful) and they give you eye masks to help you sleep, socks to wear, all the free tea and wine you want, and on top of that they're so nice about it! Usually when I fly in coach, esp internationally, the staff makes you feel a little like 2nd class. But not BA, which is why I hope to do much more business with them in the future.
