Welcome to FT nwoody2001, I’m sure a more official greeting will be forthcoming from one of our Ambassadors soon!

I have no specific insight into your particular issue here, but I recall that sometimes BA IT is a little flaky, and that the actual cost isn’t properly calculated on the first page when redeeming - you have to click through to the next page and then it works itself out. Is it possible that this is what’s happening here?
