But the point is that they haven't. And it's by no means certain that they will.
So, notwithstanding the de facto authority of the Commander, once airborne the sanctions that are available against a passenger who removes his/her mask are pretty well non-existent. Suggesting that the F/As get the zip-ties out, or the aircraft divert, is nonsense.
