Feb. 8, 2012 - Both the U.S. House of Representatives and the Senate agreed to the conference report on a bill that provides a long-term reauthorization of the Federal Aviation Administration (HR 658). The FAA has experienced over 20 short-term reauthorizations since September 2007. A main sticking point centered on labor issues -- in particular, changes to the National Mediation Board that would make it more difficult for airline and railway workers to unionize.

On Feb. 3, the House agreed to the conference report by a vote of 248-169 while the Senate agreed on Feb. 6, by a vote of 75-20. The President is expected to sign the measure.

The measure was opposed by unions such as the Communications Workers of America, the International Association of Machinists and Aerospace Workers, and the International Brotherhood of Teamsters. The measure was supported by the Aerospace Industries Association, the Air Transport Association, and the Associated General Contractors of America. Air transportation unions were split on the issue: the Association of Professional Flight Attendants opposed the measure while the Air Line Pilots Association favored the bill overall, stating that although they "would have preferred that certain provisions unrelated to aviation safety had not been included, the compromise was necessary to set the stage for the passage of this extremely important funding bill."
