Boeing 717-200 vs. Boeing 737-600

The Boeing 717-200 is a narrow-body, twin-engine jetliner designed for regional and short to medium-haul routes. Characterized by its efficiency and operational flexibility, it caters to airlines requiring a reliable and cost-effective solution for less dense routes. Developed as a part of the Boeing family, the 717-200 first entered service in 1998, marking Boeing's entry into the regional jet market. It was produced until 2006, with a focus on meeting the specific demands of regional air travel. The aircraft's production history reflects Boeing's strategy to offer a range of jetliners tailored to various market segments.

With dimensions of 37.8 meters (124.0 feet) in length and a wingspan of 28.5 meters (93.3 feet), the 717-200 is ideally sized for operations at smaller airports. It typically accommodates 110 passengers, providing a comfortable and efficient travel experience on regional journeys. Powered by two rear-mounted Rolls-Royce BR715 engines, the Boeing 717-200 delivers a total thrust of 190.0 kN (42,800 lbf). Its fuel capacity of 16,670 liters (4,404 US gallons) supports a range of 3,815 kilometers (2,060 nautical miles), making it suitable for various regional routes. The aircraft has a cruise speed of 822 km/h (511 mph).

In the competitive regional jet market, the Boeing 717-200 stands as a contender against models like the Bombardier CRJ Series and Embraer E-Jets. Its introduction provided airlines with a practical and economical option for regional networks, balancing the needs for capacity, range, and cost-efficiency. Airlines such as Delta Air Lines, Hawaiian Airlines, and QantasLink have utilized the 717-200 for its operational efficiency and adaptability. Not many 717s are still in service today. Delta is one of the last airlines to be phasing out its own fleet.

The Boeing 717-200's legacy in commercial aviation is defined by its role in regional air travel. While its production has concluded, the 717-200 continues to be recognized for its contribution to the regional aviation segment.

Launched in 1998, the Boeing 737-600 is the smallest aircraft in the 737 Next Generation (NG) series. It succeeded the 737-500, and was a significant evolution in Boeing's narrow-body offerings. It featured many upgraded features from the previous 737s, including aerodynamics, engines, and avionics. As the smallest NG variant, the 737-600 was designed for efficiency and adaptability, catering to airlines requiring a compact jet for short to medium-haul routes.

This aircraft extends 102.4 feet (31.2 meters) in length with a wingspan of 112.6 feet (34.3 meters). The 737-600, with a typical seating capacity for 123 passengers, offers an ideal balance between passenger comfort and efficiency, making it a fitting choice for airlines serving routes with moderate passenger demand. Equipped with two CFM International CFM56-7B20 engines, the 737-600 has a total thrust of 45,400 lbf (202.0 kN). This engine power, coupled with a fuel capacity of 6,868 US gallons (26,000 liters), gives the -600 a range of 3,051 nautical miles (5,650 kilometers). The 737-600 has a cruise speed of 528 mph (850 km/h) enabling airlines to maintain efficient and swift operations, particularly beneficial for regional network connections.

In the late 1990s and early 2000s, the Boeing 737-600 competed with aircraft such as the Airbus A318 and Bombardier CRJ series, offering airlines a modern alternative in the narrow-body market. Airlines including Scandinavian Airlines (SAS), Westjet, and Air Algerie operated the Boeing 737-600. Ultimately, the -600 variant was not a popular model of the 737 due to its economics. The -700, only slightly heavier, had a much greater payload. Additionally, the larger market was moving more towards higher capacity narrow-bodies with lower unit costs and greater revenue opportunities.
