I also wonder how long until AF (America First, not Air France in this case) becomes a policy applied to the US's airspace. It would seem counter intuitive to do, but with tariffs being used how they are, it wouldn't surprise me that soon foreign airlines may be at a disadvantage. This would really flip things against BA and it's dominance on the routes. Don't want to get drawn into a discussion of the politics here. Just hypothesizing what could potential happen if US and European continent relations sour further.
