Boeing 737-900ER

739 B739 Out of Production

Longest of the Boeing 737 Next Generation series, the 737-900ER added extra emergency exits and a flat rear pressure bulkhead to carry more passengers than earlier models. Two-class seating is about 178, rising to 220 single-class, and two CFM56-7B27 turbofans give a range near 5,925 km at 842 km/h. First flown in 2006, the aircraft is 42.1 metres long with a 34.3-metre wingspan and a maximum takeoff weight of 85,130 kg. The Extended Range designation gave the type transcontinental capability in a high-density single-aisle airframe, positioning it as the NG family's answer to larger narrow-body demand before the 737 MAX 9 succeeded it.

Frequently Asked Questions

The Boeing 737-900ER typically seats 178 passengers in a two-class configuration. In a single-class high-density layout, it can carry up to 220 passengers. The ER (Extended Range) designation distinguishes it from the standard 737-900, which had limited range with a full passenger load due to the lack of additional fuel capacity.

The Boeing 737-900ER has a maximum range of approximately 5,925 km (3,200 nautical miles) with a full passenger load. This was achieved by adding two additional fuel tanks and flat rear pressure bulkhead compared to the standard 737-900. The aircraft also features dual overwing emergency exits and a tail skid for increased rotation angles during takeoff.

The A321-200 carries about 7 more passengers (185 vs 178) and has a wider cabin than the 737-900ER. The A321 also has a marginally greater range at 5,950 km. However, the 737-900ER offers significant fleet commonality benefits for airlines already operating other 737 NG variants. Delta Air Lines and Lion Air have been the largest 737-900ER operators, using them on high-demand domestic routes.

The 737-900ER is the longest variant of the 737 Next Generation family at 42.1 m. It features blended winglets (standard) and two overwing emergency exits per side, similar to the A321. The tail has a small skid bumper underneath to protect against tail strikes during rotation. Compared to the 737-800, the additional fuselage stretch is visible as extra window rows aft of the wing.

The Boeing 737 MAX 9 is the designated replacement for the 737-900ER. The MAX 9 offers similar passenger capacity with improved fuel efficiency from the LEAP-1B engines and split-tip winglets. Alaska Airlines has been a prominent operator transitioning from the 737-900ER to the 737 MAX 9. The MAX 9 gained attention in January 2024 when an Alaska Airlines aircraft experienced a door plug blowout, leading to temporary inspections across the fleet.
