I do think it's marginal though: the BA AMEX really only works for me because I have the work travel to drive the spend through it, and I value premium travel enough that I would probably be paying cash for some of these trips if I wasn't redeeming the avios+241.
Called it exactly how I see it.
Where revenue fares have come up that have been of good to exceptional value, we've ended up using the 2-4-1 to position on occasions...
I think overall though there is more value in having the card than not having it.
