Keep in mind ... and ccording to the news reports ... four major USA airlines suspended their flights - indefinitely - BEFORE the FAA even acted.
It sounds like, to me, an “airline thing” and safety of their passengers, not to say anything about potential lawsuits.
And in fact, today, I read where one of the major airlines says that they evaluate their flights on their own, apart from the FAA, and they have decided on their on their own to not fly there.
Your information is incorrect. No matter how many times you quote some source, the source is suspect when they don’t even know how many flag carriers from the US service Tel Aviv.
