WASHINGTON (AP) -- With flight delays mounting, White House officials and key members of the Senate reported significant progress Thursday night on legislation to end air traffic controller furloughs blamed for inconveniencing large numbers of travelers.
Under a draft compromise circulated among lawmakers, the Federal Aviation Administration would gain authority to transfer up to $253 million from accounts that are flush into other programs, to "prevent reduced operations and staffing" through the Sept. 30 end of the fiscal year.
Officials said they hoped for passage later in the evening, after most members of the Senate already had left the Capitol to begin a 10-day vacation.
Sen. Susan Collins, R-Maine, a participant in the talks, said the measure would "prevent what otherwise would have been intolerable delays in the air travel system, inconveniencing travelers and hurting the economy."
Earlier, lawmakers involved in the talks said there was general agreement that the FAA should be given additional flexibility in allocating its share of $85 billion in across-the-board spending cuts that took effect last month at numerous federal agencies.
But consensus on the details was elusive, and without legislation, the furloughs and resulting flight delays were virtually certain to persist at least until Congress returns on May 6 after a weeklong vacation.
"I want to do it right now. There are other senators you'd have to ask what the hang-up is," said Sen. Mark Udall, a Colorado Democrat who helped author one of several proposals under consideration.
Any measure that cleared the Senate would also have to be approved by the House. Officials there indicated earlier in the day they were willing to do so, depending on the details.
For the White House and Senate Democrats, the discussions on legislation relating to one relatively small slice of the $85 billion in spending cuts marked a shift in position in a long-running struggle with Republicans over budget issues. Similarly, the turn of events marked at least modest vindication of a decision by the House GOP last winter to finesse some budget struggles in order to focus public attention on the across-the-board cuts in hopes they would gain leverage over President Barack Obama.
The talks unfolded as the FAA said there had been at least 863 flights delayed on Wednesday "attributable to staffing reductions resulting from the furlough."
The Professional Aviation Safety Specialists, a union that represents FAA employees, reported a number of incidents it said were due to the furloughs.
In one case, it said several flights headed for Long Island MacArthur Airport in New York were diverted on Wednesday when a piece of equipment failed. "While the policy for this equipment is immediate restoral, due to sequestration and furloughs it was changed to next-day restoral," the union said.
It added it was "learning of additional impacts nationwide, including open watches, increased restoration times, delays resulting from insufficient funding for parts and equipment, modernization delays, missed or deferred preventative maintenance, and reduced redundancy."
The airlines, too, were pressing Congress to restore the FAA to full staffing.
In an interview Wednesday, Robert Isom, chief operations officer of US Airways, likened the furloughs to a "wildcat regulatory action."
He added, "In the airline business, you try to eliminate uncertainty. Some factors you can't control, like weather. It (the FAA issue) is worse than the weather."
In a shift, first the White House and then senior Democratic lawmakers have signaled a willingness in the past two days to support legislation that alleviates the budget crunch at the FAA, while leaving the balance of the $85 billion to remain in effect.
Obama favors a comprehensive agreement that replaces the entire $85 billion in across-the-board cuts as part of a broader deficit-reduction deal that includes higher taxes and spending cuts.
One Senate Democrat, Sen. Patty Murray of Washington, noted that without the type of comprehensive deficit deal that Obama favors, a bill that eases the spending crunch at the FAA would inevitably be followed by other single-issue measures. She listed funding at the National Institutes of Health as one example, and cuts that cause furloughs of civilians who work at military hospitals as a second.
At the same time, Democratic aides said resolve had crumbled under the weight of widespread delays for the traveling public and pressure from the airlines.
Sen. John Thune, R-S.D., involved in the discussions, said the issue was big enough so "most people want to find a solution as long as it doesn't spend any more money."
Officials estimate it would cost slightly more than $200 million to restore air traffic controllers to full staffing, and another $50 million to keep open smaller air traffic towers around the country that the FAA has proposed closing.
Across the Capitol, the chairman of the House Transportation Committee, Rep. Bill Shuster, R-Pa., said, "We're willing to look at what the Senate's going to propose."
He said he believes the FAA has the authority it needs under existing law to shift funds and end the furloughs of air traffic controllers, and any legislation should be "very, very limited" and direct the agency to use the flexibility it already has.
In a reflection of the political undercurrents, another House Republican, Rep. James Lankford of Oklahoma, said FAA employees "are being used as pawns by this (Obama) administration to be able to implement the maximum amount of pain on the American people when it does not have to be this way."
The White House and congressional Democrats vociferously dispute such claims.
