WASHINGTON (TIP): The Senate approved hurry-up legislation on Thursday night to end air traffic controller furloughs blamed for inconveniencing large numbers of travelers as flight delays mounted. A House of Representatives vote on the measure was expected as early as Friday, with lawmakers eager to embark on a weeklong vacation. For the White House and Senate Democrats, the discussions on legislation relating to one relatively small slice of the $85 billion in automatic spending cuts that took effect last month after Washington failed to reach a long-term deal to rein in deficit spending.

But it 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 Republicans in the House of Representatives 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. Under the legislation, 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. In addition to restoring full staffing by controllers, Senate officials said the available funds should be ample enough to prevent the closure of small airport towers around the country.

The FAA has said it will shut the facilities as it makes its share of $85 billion in across-the-board spending cuts that took effect last month at numerous government agencies. The Senate acted as the FAA said there had been at least 863 flights delayed on Wednesday “attributable to staffing reductions resulting from the furlough.” There was no immediate reaction at the White House, although administration officials participated in the negotiations that led to the deal and evidently registered no objections.

Senate approval followed several hours of pressure-filled, closed-door negotiations, and came after most senators had departed Congress on the assumption that the talks had fallen short. Officials said a small group of senators insisted on a last-ditch effort at an agreement before Congress adjourned for a vacation that could have become politically problematic if the flight delays continued. 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.
