Bombardier CRJ-700 vs. McDonnell Douglas DC-9-30

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.

The McDonnel Douglas DC-9-30, a narrow-body jet airliner first introduced in 1966, stands as a significant aircraft in the evolution of commercial aviation. Designed during an era of rapid growth in air travel, the DC-9-30 was developed to meet the demands of short to medium-haul routes, offering airlines a more efficient and practical alternative to the larger jetliners of the time. The Series 30 of the DC-9 included four main sub-variants, -31, -32, -33, and -34. During its production, the -30 was by far the most popular model of the DC-9 with 585 units delivered.

This aircraft was initially developed as the Douglas DC-9, prior to August 1967 merger with McDonnell Aircraft. The DC-9-30 measures in at 36.4 meters (119.3 feet) in length. This size enabled it to operate efficiently in smaller airports and on shorter runways - a niche that was underserved at the time of its introduction. Powered by a pair of Pratt & Whitney PWJTD engines, the DC-9-30 has a total thrust output of 134.0 kN (30,000 lbf). Its fuel capacity of 13,900 liters (3,672 US gallons) gives the DC-9-30 a range of approximately 2,800 kilometers (1,512 nautical miles). This range was particularly advantageous for airlines looking to serve regional networks with an efficient and reliable jet.

The DC-9-30's typical five abreast seating layout can fit around 115 passengers, with a maximum of 127 in a high-density layout.

In its market segment, the McDonnel Douglas DC-9-30 was a key competitor to other short-haul aircraft of the era. Its introduction provided airlines with a jetliner that was not only smaller and more versatile than the larger, long-haul aircraft but also more efficient and economical for short to medium-range routes.

Airlines such as Delta Air Lines, Eastern Air Lines, and TWA were prominent operators of the DC-9-30, utilizing its capabilities to enhance their regional route networks. The aircraft's role in these fleets demonstrated its effectiveness in bridging the gap between propeller-driven airliners and larger jets, contributing significantly to the growth of regional air travel.

The McDonnel Douglas DC-9-30's production and service history highlight its importance as a practical and versatile aircraft in commercial aviation. The last DC-9 to ever be built was delivered in 1982. After its retirement, McDonnell Douglas went on to produce the MD-80 and the MD-95.
