I was commenting on that earlier to some folks. Even though not involved in the snow closures, other major hub airports that feed to the NE ones, like ATL, will have a lot of secondary effects from this. Not the least of which being people sleeping in the terminal waiting areas.
I seem to remember a lot of warnings pre-XMAS season of another planned attack throughout the US.
We heard about the postal bomb at the Swiss Embassy in Rome.
If more intel arose here, of airline associated attacks, this would appear to be a good justification to preclude such activity.
