With the U.S. Department of Justice stepping in to intervene and block the merger between American Airlines (OTCQB: AAMRQ) and US Airways (NYSE: LCC), citing reduced competition and boosted fares are the main reasons for stopping the merger, Jet Blue is looking like the next best choice for either of the airlines. Jet Blue is a smaller airlines but has a great and well respected presences on the east coast especially in New York, the busiest hub for air travel. Aside from that the small size of the company makes it less likely that the DoJ will step in and block a merger because there will still be room for competition.
