A day after flight delays plagued much of the U.S., air travel is smoother Tuesday. But the government is warning passengers that the situation can change by the hour as it runs the nation's air traffic control system with a smaller staff.
Airlines and members of Congress urged the Federal Aviation Administration to find other ways to make mandatory budget cuts besides furloughing controllers. While delays haven't been terrible yet, the airlines are worried about the long-term impact late flights will have on their budgets and on fliers.
US Airways CEO Doug Parker said he doesn't believe the furloughs can be tolerated for long.
Transportation Secretary Ray LaHood pointed the finger at Congress, which forced government agencies to cut spending after failing to reach a deficit-reduction plan.
