I got the email below and it was posted on ThePointsGuy blog. I might book a flight today to London, but if I don't I will offer my code for someone else's use. Also, ThePointsGuy seems to be doing the same on his blog with people posting their codes as well. IF you have a code post it below if you aren't going to use it. If you use a code, post that you have used it. I will update the original post with the most accurate codes that are still vaild and haven't been used.
