Are you sure this is related? JSX is selling tickets like normal, and the article says nothing about any actions taken, only that the TSA hasn't made public it's plans yet.
So far they've had to pull out of a few airports when FBOs stop hosting them, mostly without explanation. The same FBOs that allow part 135 operators, some owned by the majors, to run. Seems related.
Regulations are written in blood, but this one just looks like it's written in green.
