Overview of Boeing 737-900’s Journey
The Boeing 737 was recognized as the most delivered jet-powered airliner until recently, with the 737NG being the third generation widely used against the Airbus A320 family. However, within the 737NG variants, the Boeing 737-900 emerged as a less successful model compared to its peers. This article examines why the Boeing 737-900 did not achieve significant sales.
Development of the Boeing 737NG
The original Boeing 737 launched with its 737-100 model in 1968, progressing to the 737-200. These, along with their variants, were collectively dubbed the 737 Original. In response to the McDonnell Douglas MD-80, Boeing introduced the 737 Classic family, featuring the 737-300, 737-400, and 737-500 models, which greatly increased sales over the original series.
With Airbus A320’s introduction in 1988, Boeing needed a modernized version of the 737 Classic to compete. Thus, the 737NG was born, integrating a full glass cockpit, larger fuselages, new wings, and CFM56-7 engines.
Why the Boeing 737-900 Struggled
The 737-900 first appeared at the behest of Alaska Airlines, entering service in 2001. A straightforward stretch from the 737-800, it targeted the Airbus A321 market but was still the smallest compared to the A321 and Boeing 757-200. Despite its intention as a replacement for the 757, the 737-900’s limited range and similar exit configuration to the 737-800 made it less appealing. Budget airlines could find no additional benefits due to existing seat limits.
| Airline | Boeing 737-800 | Boeing 737-900 |
|---|---|---|
| Alaska Airlines | 159 / 162 | 178 |
| United Airlines | 166 | 179 |
| Southwest Airlines | 175 | N/A |
| Ryanair | 189 | N/A |
Addressing the Issues: The 737-900ER
In 2005, the 737-900ER was launched to address the 737-900’s shortcomings, featuring additional exit doors, an increased Maximum Takeoff Weight (MTOW), and optional fuel tanks for extended range. These enhancements allowed the 737-900ER to perform transcontinental flights, making it more versatile and successful, eventually achieving 505 sales.
| Aircraft | Sales |
|---|---|
| Boeing 737-900 | 52 |
| Boeing 737-900ER | 505 |
| Boeing 757-200 | 913 |
| Airbus A321 | 1,784 |
Future Prospects with the Boeing 737 MAX 10
Efforts to challenge the Airbus A321neo continue with the development of the Boeing 737 MAX 10, which promises reduced per-seat costs. Despite its delayed certification, it has received over 1,200 orders, illustrating potential robustness against the A321neo.
737-900’s Legacy
Unlike other Boeing 737 models, the 737-900 didn’t capture a significant market share against the A321. However, its successor, the 737-900ER, addressed many issues and achieved moderate success. As the MAX 10’s certification looms, Boeing aims for its most ambitious attempt to contend with the Airbus A321neo.
