Boeing 737-300 vs. Bombardier CRJ-700

The Boeing 737-300, launched in the early 1980s, is a seminal model in the 737 family, known for ushering in the era of modern narrow-body jetliners. As the first of the 737 Classic series, it was developed to meet the growing demand for more efficient and higher-capacity short to medium-haul aircraft. Compared to the Original 737 models, the -300 featured new wings, a redesigned tailfin, and improvements inside the cabin. Fast forward a bit, the 737-300 was eventually replaced by the 737-700 of the Next Generation series.

The 737-300 stretches 109.6 feet (33.4 meters) from nose to tail, with a wingspan of 94.5 feet (28.8 meters). This aircraft was Boeing's answer to the need for a larger capacity in the single-aisle market, accommodating 128 passengers in a typical two-class layout. Its increased length over its predecessor, the 737-200, allowed for additional seating, making it a more economical choice for airlines.

Equipped with two CFM International CFM56-3B1 engines, the 737-300 produces a total thrust of 44,000 lbf (196.0 kN). This enhancement in power, combined with a fuel capacity of 5,310 US gallons (20,100 liters), extended the aircraft's range to 2,376 nautical miles (4,400 kilometers). The 737-300's cruise speed of 495 mph (796 km/h) made it a swift and efficient option for airlines, reducing flight times on popular domestic and regional routes.

The 737-300 marked a shift in the commercial aviation landscape, competing with models like the McDonnell Douglas MD-80. Its launch was pivotal for Boeing, demonstrating the company's ability to innovate and adapt to market shifts. The 737-300's popularity was driven by its improved efficiency, greater capacity, and enhanced performance, meeting the needs of airlines expanding their short-haul operations.

Major carriers such as Southwest Airlines and United Airlines incorporated the Boeing 737-300 into their fleets, capitalizing on its operational advantages. The American carriers purchased a majority of the -300, with 299 units between the two airlines. The aircraft's role in these fleets was significant, as it enabled airlines to offer more frequent services and open new routes, particularly in the domestic and regional markets.

The Bombardier CRJ-700 is a narrow-body regional aircraft, designed for short to medium-haul routes. Introduced in 1999 as a member of the Canadair Regional Jet series, the CRJ-700 is a stretched derivative of the CRJ200. Regional carriers use CRJs, like the -700, to serve smaller cities and transport passengers to hub airports for connecting flights.

The CRJ-700 is approximately 32 meters (106.0 feet) long, and 23.3 meters (76.4 feet) from wing tip to wing tip. This aircraft is tailored for operations in smaller airport environments with limited runway lengths. The size and design of the CRJ-700 facilitate efficient airport operations and quick turnarounds, essential for the high-frequency schedules typical of regional airlines. Powered by General Electric engines capable of delivering a maximum thrust of 122.6 kN (27,600 lbf), the CRJ-700 is equipped for a range of approximately 2,593 kilometers (1,400 nautical miles). This range allows airlines to deploy the aircraft on a wide array of routes, from short hops to longer regional journeys, without sacrificing efficiency or performance. CRJ-700 flights can typically range anywhere from 30 minutes to a couple hours in duration.

The cabin of the CRJ-700 is designed to seat around 66-78 passengers in a standard single-class configuration. Features such as improved cabin lighting, ergonomic seating, and overhead storage contribute to an enhanced passenger experience. Additionally, the cabin's design allows for quick and efficient boarding and deplaning, a key consideration in regional air travel.

In the competitive landscape of regional aircraft, the Bombardier CRJ-700 holds its ground against counterparts like the Embraer E175. The CRJ-700's introduction served to address a growing market demand for regional jets that could offer better performance, more seats, and improved passenger comfort compared to earlier models. US-based airlines including American Eagle, Delta Connection, and United Express have utilized the CRJ-700 extensively. Its operational strengths make it well-suited for building and maintaining effective regional networks, providing vital connectivity between smaller cities and major airports. The aircraft's role extends beyond just transportation; it facilitates economic growth and accessibility to remote areas, proving to be a valuable asset in the regional aviation sector. At launch, the -700 had an estimated sale price of $35 million. Production for the entire CRJ family was discontinued after 2021.
