Tankering fuel in is a partial answer but it's just a stop gap. If the fuel isn't there at the airport, especially major hubs like ATL and IAD, most of the flying will grind to a halt and what fuel is left will be allocated to emergency relief efforts.
I truly hope this is journalistic excess. The consequences of a shutdown of several important airports would be severe.
Meanwhile, since I live near Atlanta I can tell you first hand that we're already out of gasoline. Nadda, zip, the pumps are empty.
