What GAO Found
The Department of Justice’s (DOJ) antitrust review will be a critical step in the proposed merger between American Airlines (American) and US Airways. DOJ uses an integrated analytical framework set forth in the Horizontal Merger Guidelines to determine whether the merger poses any antitrust concerns. Under that process, DOJ assesses, among other things, the extent of likely anticompetitive effects of the proposed merger in the relevant markets, in this case, airline city-pair markets, and the likelihood that other airlines may enter these markets and counteract any anticompetitive effects, such as higher fares. DOJ also considers efficiencies that a merger or acquisition could bring—for example, consumer benefits from an expanded route network. The Department of Transportation (DOT) aids DOJ’s analysis.
Airlines seek mergers to reduce costs and improve revenues. GAO has previously reported that mergers can result in increased revenues by offering improved network connections and schedules, but also through higher fares on some routes. Cost savings can be generated by eliminating redundancies and operational efficiencies, including reducing service, but can be muted by problems in combining different aircraft, technologies, and labor forces. In the case of US Airways and American, they estimate that a merger would yield $1.4 billion in annual benefits from increased revenues and reduced costs.
If not challenged by DOJ, the merged American would surpass United to become the largest U.S. passenger airline by several measures. While US Airways and American overlap on only 12 nonstop routes, no other nonstop competitors exist on 7 of those 12. Our analysis of 2011 and 2012 ticket data also showed that combining these airlines would result in a loss of one effective competitor (defined as having at least 5 percent of total airport-pair traffic) in 1,665 airport- pair markets affecting more than 53 million passengers while creating a new effective competitor in 210 airport-pairs affecting 17.5 million passengers. However, the great majority of these markets also have other effective competitors.
