The 737-900ER incorporates a new pair of exit doors and a flat rear-pressure bulkhead that allow a maximum capacity of 220 passengers in a single-class layout. Aerodynamic and structural design changes - including strengthened wings, a two-position tailskid, enhancements to the leading- and trailing-edge flap systems, optional Blended Winglets, and auxiliary fuel tanks - will allow the 737-900ER to accommodate higher takeoff weights and increase its range to 3,200 nautical miles (5,900 km).

The 737-900ER has substantial economic advantages over competing models, including 6 percent lower operating costs per trip and 4 percent lower operating costs per seat than its competitor -- which is more than 9,550 pounds (4,340 kg) heavier. The 737-900ER joins the 737-600, -700, -700ER and -800 airplanes and will share the same industry-leading reliability of the other Next-Generation 737 series models.

To date, eight customers have placed orders for 227 Next-Generation 737-900ERs. The 737 is the best-selling commercial jetliner in history, with more than 7,700 orders from more than 245 customers around the world. Boeing has more than 2,000 unfilled orders for the airplane with a value exceeding $145 billion at current list prices.

Lion Air received the first 737-900ER in April 2007 when the airplane was delivered in a special dual paint scheme that combined the Lion Air lion on the vertical stabilizer and the Boeing livery colors on the fuselage. The airline has received a total of nine 737-900ERs to date. Lion Air operates an all-Boeing fleet and is the largest low-fare airline in Asia, with traffic approaching 1 million passengers per month since the airline began operations in June 2000.
