Continental converted orders for 12 Next-Generation 737s to the new 737-900ER model. Boeing will deliver Continental’s first 737-900ER in 2008. Last month Continental Airlines ordered an undisclosed mix of 24 Next-Generation 737s along with 10 787 Dreamliners.
Boeing claims the 737-900ER will have substantial economic advantages over competing models, including nine percent lower operating costs per trip and seven percent lower operating costs per seat than the A321, which is more than 10,000 pounds (4,536 kg) heavier.
Aerodynamic and structural design changes to the 737-900ER include strengthened wings, a two-position tailskid and enhancements to the leading and trailing-edge flap systems, which provide the 737-900ER higher takeoff weight capability and increased range than the base model.
