Back to the original thread question about airspace restrictions for civilian traffic: not yet but the plan is there waiting to be activated . If the Brown stuff hits the fan and the Turkish-Iran corridor closes it's going to hurt a lot to f Airlines with much longer routes .
Hopefully the start of this will be a NATO coordinated event and some form of warning will be issued to divert aircraft in flight .
But experience shows us that a full staged war is rarely preceded by a NOTAM .
