American Airlines said on Tuesday it took delivery of the first of 14 Boeing (BA.N) extended range 777-300 planes it has ordered.
The twin-aisle plane, which has more than 300 seats and offers first class, business class and main cabins, will be used on the Dallas/Fort Worth to Sao Paulo route in early 2013.
American, a unit of AMR Corp AAMRQ.PK, said the plane would also fly to London Heathrow Airport from Dallas/Fort Worth and New York's John F. Kennedy Airport.
American, which is currently operating under Chapter 11 bankruptcy protection and weighing a potential merger with US Airways Group LCC.N, said it was the first U.S. airline to order and take delivery of the 777-300ER.
The carrier is modernizing its fleet and has more than 550 planes on order.
