American orders 260 new planes, including Boeing Max 10s, and plans bigger first class

American Airlines said Monday it is ordering 260 new narrow-body jets, including dozens of Boeing's long-delayed 737 Max 10.

The order includes 85 of Boeing's 737 Max 10 planes and 85 of the Airbus A321neo, aircraft it says will help it upgauge on domestic and short-haul international routes. The Fort Worth, Texas-based airline is also ordering 90 Embraer E175 planes.

American's order is a vote of confidence for Boeing, which is struggling with a series of production flaws and certifications of new planes that have taken years longer than originally expected. Scott Kirby, CEO of rival carrier United Airlines, said earlier this year that his airline has been weighing fleet plans without its Max 10s because of the delays.

American said it would also convert orders for 30 Boeing 737 Max 8 planes, a model that is already a staple of its fleet, into the larger 737 Max 10s. The order includes purchase options for another 193 planes from the three manufacturers.

American is planning to grow its first class on some of its narrow-body planes, the carrier also said Monday alongside its first investor day in more than six years. Starting in 2025, it will retrofit its older Airbus A319 and A320 planes to increase the number of first-class seats from eight to 12 and 12 to 16, respectively.

The airline is planning to retire its fleet of 50-seat, single-class regional jets in favor of the two-class planes, with in-seat power and satellite Wi-Fi by the end of the decade. The planes will be operated by American's wholly-owned regional airlines.

The aircraft orders are included in American's previous capital expenditure targets.
