Airports don't "shut down" because of jet fuel shortages. Not every airport necessarily has to be a "filling station" for every flight of every airline or general aviation customer.
It seems that some US airports have been quite low on fuel stocks for some weeks; see thread below!

This situation will be a further blow to already hard hit US airline companies and may cause the price of Jet Fuel to rocket still further. Ouch!
