(Fox News) Airline and pilot organizations have filed suit in a bid to stop the Federal Aviation Administration from going through with furloughs set to kick in this weekend, echoing the claims of congressional Republicans that the agency could have found the savings elsewhere.

The suit comes after FAA Administrator Michael Huerta testified Thursday that the public should expect flight delays as furloughs take effect Sunday for air traffic controllers. He said FAA officials could find no other way to cut $637 million from the agency’s budget as required by the sequester.
