If you thought airport wait times were long, get ready for worse. How about an extra hour to go through security? And, international travelers, brace for this — four hours to clear customs?

These are likely scenarios at the nation’s airports when the much-feared $85 billion of forced U.S. budget cuts hit in March. Many federal agencies — including those that handle airport security, customs, and air traffic control — will be forced to furlough employees, which means workers will have to stay away from their jobs for no pay for certain time periods over the next seven months.
