The Boeing 737-800 is a narrow-body, twin-engine airliner from the 737 Next Generation (NG) family, in airline service since 1998. It seats 162 passengers in a typical two-class layout (up to 189 in single class), covers approx. 2,900 nautical miles (5,370 km), and is powered by two CFM56-7B turbofans. With more than 4,000 delivered, it is the most-delivered 737 variant to date. The rest of this article walks through the full specifications, development history, cabin features, and a comparison with the larger 737-900 and 737-900ER.
Overview of the Boeing 737-800
The Boeing 737-800 is a core member of the 737 family and one of the most widely used short- to medium-haul airliners. The narrow-body evolved from its predecessor, the 737-700, to give airlines more seats on the same airframe generation.
As part of the Next Generation (NG) series, the 737-800 exemplifies the perfect balance between operational efficiency and passenger capacity. Its versatility allows airlines to maximize revenue potential while maintaining the reliability that has become synonymous with the 737 family name.
History and Development of the Boeing 737-800
The early 1990s marked the beginning of the 737-800’s development as Boeing sought to enhance its successful 737 Classic series. Launched in September 1994, the aircraft incorporated cutting-edge technology while maintaining compatibility with existing 737 models, ensuring cost-effective pilot training for airlines.

Engines: What Powers the 737-800
Every 737-800 flies with two CFM56-7B turbofans – the only engine type offered on the 737 Next Generation family. Built by CFM International, a joint venture of GE Aerospace and Safran Aircraft Engines, the CFM56-7B is rated between 19,500 and 27,300 pounds of thrust depending on the version, and its commonality across the -600, -700, -800, and -900 keeps spares, tooling, and training uniform for operators.
With thousands of 737-800s in service, the CFM56-7B is one of the most frequently removed and shipped engines in commercial aviation. Off the wing, each unit – approx. 5,200 lb (2,360 kg) dry – is moved and stored on a dedicated CFM56-7B engine stand, a cradle-and-base fixture built for its mounts and weight. Our guide to aircraft engine stand types explains how these fixtures differ between engine models.

Comparing the Boeing 737-800 with Other Aircraft
The Boeing 737-800 competes head-to-head with the Airbus A320, its closest rival in the narrow-body class. Passengers often favor the A320 for its wider cabin, while the two types stay closely matched on performance and range.
| Aspect | Boeing 737-800 | Airbus A320 |
|---|---|---|
| Passenger Comfort | Traditional design, variable comfort based on airline configuration | Generally preferred for comfort, wider cabin feel |
| Performance | Strong operational efficiency, reliable performance | Comparable efficiency, modern flight characteristics |
| Route Flexibility | Excellent balance of capacity and range | Similar capabilities, good network versatility |
While newer aircraft models like the 737 MAX and A320neo offer enhanced fuel efficiency and extended range capabilities, the 737-800 maintains its position as a dependable workhorse in many airline fleets. In practice, comfort depends more on each airline’s configuration and interior choices than on the airframe itself.
Boeing 737-800 vs 737-900 and 737-900ER
The 737-900 and 737-900ER are stretched versions of the same NG airframe: 2.6 meters longer, with the same wing, cockpit, and CFM56-7B engines. The -900ER adds an extra exit pair and optional auxiliary fuel tanks, which raises both its seating limit and its range. Pilots fly all three under a single type rating, and the 737-800 remains the best-selling of the three by a wide margin.
| Feature | 737-800 | 737-900 | 737-900ER |
|---|---|---|---|
| Length | 39.5 m (129 ft 6 in) | 42.1 m (138 ft 2 in) | 42.1 m (138 ft 2 in) |
| Typical two-class seating | 162 | approx. 170-177 | approx. 175-180 |
| Maximum seating | 189 | 189 | 220 |
| Range | approx. 2,935 nmi | approx. 2,750 nmi | approx. 2,950 nmi |
