Due to the terror alerts people are forbidden from bringing any materials onto the planes everything has be checked in. Now as duty free is passed the check in area this means that unless people can have a separate Duty Free check in. They will be unable to buy anything in Duty free, other then food that they consume prior to getting on the plane. Sales of Whiskey, Cigarettes, electronics will all be gone.
How many jobs will lost due to this is still unclear but could be many. Will the airports install checks prior to duty free? This attack may have more effect on aviation then 9/11.
