In January 2013, Republic Airways Holdings reached a capacity purchase agreement with American Airlines to operate 47 Embraer E175 airplanes under the American Eagle brand beginning in mid-2013. The regional jets would be deployed out of American's Chicago hub. In addition, Republic would have options to purchase an additional 47 Embraer aircraft beginning in 2015. Republic took first delivery of the E175 jets in July 2013 and service began August 1, 2013, from Chicago to New Orleans, Pittsburgh and Albuquerque. Republic began using Miami as an American Eagle hub in October 2014 and in New York-JFK in May 2015.
