Some airports are starting to see flight delays and the airlines believe more could be on the way. Air traffic controllers are losing a day of work every other week. The FAA says it's a result of the automatic budget cuts Congress let take effect in March. The airlines predict as many as 30 percent of flights could be delayed. The biggest pilots union and other trade groups are suing the FAA to put controllers back on the job full time. But, the FAA claims scaling back shifts is the only way to slash 637 million dollars from the budget. But some are convinced furloughing the air traffic controllers is a political move.
