I am an American Airlines guy that's where all my miles are, but I can't bring them over from Capital One Venture Card. So I was looking at British Airways instead. It's 1,000 points to 1,000 avios. Being that I get points on my Capital One Venture Card, I can't seem to figure out in my head if it's better to use the Capital One Venture Card to get the double points or to use a Barclays card which gives me $1 per mile on American. Is this some kind of calculation that I can use for all this stuff thank you
