American Airlines has ordered 15 Bombardier CRJ900s and 15 Embraer 175 regional jets, deals with a combined list-price value of roughly $1.4 billion.
Deliveries of the CRJ900s with 76 seats to American subsidiary PSA Airlines will begin in the second quarter of 2019, Bombardier says in a media release.
The Bombardier commitment, including an additional 15 CRJ900 options, has a value at list prices of $719 million.
The Canadian airframer will outfit the aircraft with the company's new "Atmosphere" cabin, which includes overhead bins that can accommodate large roller bags.
Embraer will deliver the 15 E175s with 76 seats to American subsidiary Envoy from March 2019 to November 2019, the manufacturer says.
That deal, including options for 15 more E175s, has a value at list prices of $705 million. It follows an order by American for 10 E-Jets in October 2017.
American will use the E175s to replace smaller regional jets in its feeder fleet, the carrier says.
