American Airlines on Monday announced orders for 260 planes -- 85 Airbus A321neo, 85 Boeing 737 Max 10, and 90 Embraer E175 aircraft.
The orders include options and purchase rights for an additional 193 aircraft.
With the new planes, American aims to continue adding premium seats across its narrowbody and regional fleets that serve domestic and short-haul international routes.
As part of the Boeing order, American has switched 30 existing 737 Max 8 orders to the 737 Max 10, which is the bigger plane. The Max 10 can accommodate up to 25 more passengers than the Max 8. However, the FAA hasn't certified the Max 10 yet.
American said it looks forward to the Max 10's certification and "continuing to upgauge its fleet and provide more flexibility across its network."
As for the A321neos, American said it continues to be the largest single carrier operating A320 family aircraft.
With the E175s, American said it is "focused on bringing larger, dual-class regional aircraft into its fleet, which will continue to drive connectivity from smaller markets to the rest of the airline's global network."
American expects to retire all of its 50-seat single-class regional jets by the end of the decade, serving small and medium-size markets with larger regional jets.
The E175 aircraft will be operated by American's wholly owned regional carriers, which do business as American Eagle.
With this announcement, American said it has 440 aircraft on order, extending its aircraft order book into the next decade "so the airline can continue to meet the growing demand for air travel."
Enhancements to existing aircraft
To meet a growing demand for premium seats, American will retrofit its A319 and A320 aircraft beginning in 2025.
The retrofit will refresh the interior with power at every seat, larger overhead bins and new seats with updated trim and finish.
American's A319 fleet will be outfitted with more premium seats for a total of 12 domestic first-class seats. The A320 fleet retrofits will increase the aircraft's domestic first-class seat count to 16.
With the planned refresh of existing aircraft and the expected deliveries of new aircraft, premium seating in American's fleet is expected to grow by more than 20% by 2026.
