The Federal Aviation Administration says flights are up 10 percent this year at O'Hare International Airport. That's despite the two largest airlines cutting service to ease the worst delays in the country.
The upswing in O'Hare traffic is expected to push the airport to another year of record flights and frustrating delays.
One cause for the increased flights is that other carriers are adding O'Hare flights. That's even after United and American Airlines decided to reduce flights by five percent.
O'Hare is on a watch list of 25 airports that the Transportation Security Administration is concerned could see long lines at passenger checkpoints this summer.
