The Federal Aviation Administration said on Saturday it had suspended all employee furloughs and that it expects the U.S. air travel system will return to normal operations by Sunday evening.

The suspension follows passage on Friday of a bill allowing the agency to shift money within its budget to halt furloughs of air-traffic controllers that started April 21.

The furloughs caused thousands of flight delays and hundreds of cancellations throughout the week. The FAA said in a statement on Saturday that it expects staffing to return to normal over the next 24 hours.
