According to this article from FlightGlobal, American Airlines is close to buying 60 large regional aircraft.
The aviation and aerospace website says American will order either the Bombardier CRJ900 or the Embraer 175 and the deal should be done by the end of the year.
"The order including options and purchase rights is in the 'ballpark' of about 60 aircraft, [sources] say. This is feasible under the limits put in place by a memorandum of understanding (MOU) between American, US Airways and their respective pilots unions this past December," the article says.
As part of its pilots agreements, the new carrier could have 66- to 76-seat regional aircraft that makes up about 40 percent of the mainline narrowbody fleet after 2016. The MOU exempts the 76 CRJ900 and E-175s that are currently in US Airways' fleet.
US Airways and American expect to close their merger sometime this fall pending approval from US Airways shareholders and the U.S. Department of Justice.
American declined to comment on the possible regional aircraft purchase.
