Boeing 737-500 vs. Bombardier CRJ-900

The Boeing 737-500, introduced in 1987 as part of the 737 Classic series, is a narrow-body, twin-engine airliner designed for short to medium-haul routes. Recognized for its compact size and efficiency, the 737-500 catered to airlines needing a smaller capacity jet with the performance qualities of the larger 737 models.

At 101.7 feet (31.0 meters) in length and with a wingspan of 94.5 feet (28.8 meters), the 737-500 was adept at serving routes that required flexibility for airport size and range. This aircraft was particularly appealing to airlines for its ability to operate efficiently on shorter and less dense routes, providing a practical solution for smaller markets. While the -400 expanded on the -300, the -500 was actually constructed to considerably smaller than the -300. Comparatively, the 737-500 is closest in size and capacity to the 737-200. Powered by two CFM International CFM56-3C1 engines, the Boeing 737-500 has a total thrust capability of 40,000 lbf (178.0 kN). With a fuel capacity of 5,310 US gallons (20,100 liters), it boasts a range of 2,376 nautical miles (4,400 kilometers). The 737-500's cruise speed of 495 mph (796 km/h) contributed to its reputation as a reliable and efficient aircraft for regional travel.

In the commercial aviation landscape of its time, the Boeing 737-500 was a competitor to aircraft like the McDonnell Douglas MD-80 series. Its introduction provided airlines with a versatile option in the 737 family, bridging the gap between the larger 737 models and the need for a more economical, smaller jet. Southwest Airlines was the first customer of the -500, making their first flight in 1989. Lufthansa, United Airlines, and Continental also operated the Boeing 737-500. The aircraft played a significant role in these fleets, enabling the expansion of domestic and regional networks.

The Boeing 737-500 has faced accelerated retirement due to its smaller size. A majority of models were out of service after just 21 years in service. Most freight companies didn't even have interest in turning the -500 into a cargo jet. The 737-500 was replaced by the 737-600 of the Next Generation series.

The Bombardier CRJ-900, a member of the Canadair Regional Jet series, is a narrow-body regional jet designed for efficient short to medium-haul air travel. First entering service in 2001, the CRJ-900 was developed as an extended version of the CRJ-700, offering greater passenger capacity and slightly longer range capabilities. The -900 was the most popular CRJ variant, with over 487 deliveries throughout its production.

With an overall length of 36.2 meters (118.8 feet) and a wingspan of 24.9 meters (81.7 feet), the CRJ-900 is larger than its predecessor, enabling it to accommodate more passengers. Designed primarily for regional airline operations, the CRJ-900's dimensions allow it to operate effectively in smaller airports, which is a key requirement for regional air travel. Powered by two rear-mounted GE CF34 engines, the CRJ-900 delivers a total maximum thrust of 129.0 kN (29,000 lbf), and has a range of 2,871 kilometers (1,550 nautical miles). The aircraft's operational efficiency and range make it a versatile choice for airlines looking to connect smaller cities and towns with major airline hubs.

The cabin of the CRJ-900 is configured to seat around 81 passengers in a standard layout, with a maximum capacity of 90 passengers in a higher-density arrangement. In the regional aircraft market, the Bombardier CRJ-900 competes with other regional jets such as the Embraer E175. Airlines that operate the CRJ-900 include American Eagle, Delta Connection, and Lufthansa CityLine. These carriers utilize the CRJ-900's strengths in serving regional networks, benefiting from its ability to efficiently connect smaller airports with larger travel hubs. The aircraft's role in regional aviation is characterized by its adaptability to varying route structures and its capacity to offer a comfortable travel experience on short to medium-haul flights.

The Bombardier CRJ-900's production and operational history highlight its importance in the regional jet market. Its design and capabilities align with the needs of regional airlines, providing a practical and efficient solution for connecting communities and fostering accessibility to air travel across regional networks. The last CRJ-900 to ever be built was delivered in 2021 to SkyWest Airlines.
