The Boeing deal includes an existing order for 30 smaller Max 8 jets, which were upgraded to the Max 10. That larger plane, which has not yet received regulatory approval, can seat about 200 passengers.
American does not expect to receive its first Max 10 planes until 2028, Mr. May said. The airline expects Boeing will be able to deliver those jets, but if the manufacturer fails to, Mr. May said, American has made arrangements to replace those deliveries with other Max models or Airbus planes.
American’s A321neo planes typically seat about 200 passengers, too.
The Embraer planes are a workhorse of American’s regional subsidiaries, which typically use the jets for shorter trips, often between smaller airports or from those locations to hub airports. The E175 typically seats about 76 passengers in economy and premium classes.
Embraer, the third-largest plane manufacturer, is based near São Paulo, Brazil, and Airbus, the largest, has its headquarters in Toulouse, France. Boeing, the second biggest, is based in Arlington, Va.
“Over the past decade, we have invested heavily to modernize and simplify our fleet, which is the largest and youngest among U.S. network carriers,” American’s chief executive, Robert Isom, said in a statement. “These orders will continue to fuel our fleet with newer, more efficient aircraft so we can continue to deliver the best network and record-setting operational reliability for our customers.”
