Travel and the Cost of Terror Since the terror attacks of September 11th, 2001, the airline and travel industries in the United States have spent billions of dollars around the world to manage security threats. But what are the economic effects of these threats, and how are travelers handing them? Philip Alexiou | Washington DC 16 February 2010 Planes on tarmac Despite several high profile attempts to blow up airplanes, and heightened security measures and hassles at the airports, more Americans are flying than ever before. And it's not just in the skies: back down on the ground, ridership aboard Amtrak rail service is also rising. This year, the U.S. Transportation Security Administration will spend a billion dollars on security, twice what it spent in 2009. But the airline industry is spending much more. "Airlines around the world pay $5.9 billion annually for security," says Steve Lott of the International Air Transport Association. "Money that might go into security upgrades on an airplane like securing the cockpits doors, crew training for security issues."  Lott says a big but largely hidden part of that cost is handling data and data exchange. "Airlines have to transmit passenger lists in their passenger manefest to the govt because the govt checks passengers against watch lists and no fly lists." But how do attempted terrorist attacks - such as on Christmas day when a 23 year-old Nigerian, Umar Farouk Abdul Mutallab tried to ignite a bomb on a U.S.-bound airliner - change people's travel habits? That's a question Mike McCormick, executive director of the National Business Travel Association, put to members of his organization. "When we talked to them about that event and would they change their behavior, only two percent said they would change their travel habits in some way." Bruce McIndoe is the president of iJET Intelligence Risk Systems. He says the layers of security added year after year in response to attacks translates into billions of dollars in labor and equipment. "Once security is stepped up that causes flight delays in the system," he says, "and those delays run into the hundreds of millions of dollars for the airlines dealing with personnel, equipment that is not actively generating revenue because its sitting on the ground waiting for things to happen." Bad weather can have the same effect on productivity: planes sit, nothing moves, business stops. Terrorism aimed at airlines tends to have the same dampening effect as an accident, according to airline attorney Roy Goldberg - both happen, but people still believe airline travel is very safe. "Even with the underwear bomber in December," says Goldberg, "airline prices, shares, stock prices actually went up five persent in January. The fourth quarter of 2009 was better than 2008. I think the industry realizes these are short term problems." Recessions and travel costs affect travelers' decisions more than anything else. Analysts say an actual act of terrorism does not cost an airline as much in lost business as does the cost of trying to prevent terrorism. And, they say, airlines fear that in response to heightened security measures, travelers could begin to change where they go and how they get there. "If we get to a point where screening is much more invasive - where we require much greater background checks, people are going to start asking what do I do with my family, what do I do with my spare time?" says David Grier of George Washington University. "How do I want to explore the world and get a better sense of my place in it? That will point to other ways of transportation." Despite these concerns, the U.S. airline and travel industries hopes Americans continue to take to the air in greater numbers than ever.
