I'm guessing the answer is a definate NO, but on the far out chance that it may be possible, could I use BA Avios miles to book an AA Saver award from JFK/ORD to LHR? I know BA miles work for U.S. domestic flights on AA, but since BA doesn't offer a Saver award on its mileage scheme, could I still use their miles to book an AA TATL on the same routing as BA, but on AA to save on the fuel surcharge a bit and use less mileage then BA requires, 40,000 rather then BA's 60,000 ? Reason for asking is being here in the frozen north woods, I can't transfer my Membership Rewards points to AA, but can do so at a 1:1 ratio to BA, so if the answer is in the affirmative I'd be able to save 20,000 (x2) for my wife and me to travel to the UK in the fall. And booking the AA flight as a BA codeshare with my Avios would still require 60,000, so no help that way. Thanks.
