DoJ investigates prices at top U.S. airlines
The Justice Department wrote to major US air carriers demanding they detail decisions to limit the number of seats they offer, and what they have said about those plans to investors, securities analysts and the public.
Airlines have been asked to provide "available seat miles on a regional and system wide basis" back to January 2010 and a raft of other data. American Airlines, Delta Air Lines, United, and Southwest Airlines control some 80 percent of the domestic air travel market.
The four carriers confirmed receipt of the regulator's letter and said they are cooperating fully with the investigation. ■
