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.

Introduced in 2006, the Boeing 737-900ER is a pivotal variant in the Next-Generation 737 series, offering airlines an ideal combination of extended range and increased passenger capacity for medium to long-haul routes. This aircraft, building upon the base model of the 737-900, incorporates significant advancements that enhance its operational flexibility and efficiency.

The 737-900ER's design extends to a length of 42.1 meters (138.1 feet), making it one of the longest aircraft in the 737 family. This extended fuselage allows for a higher passenger capacity, aligning with the growing demands for more economically efficient, high-density configurations in commercial aviation. Its wingspan of 34.3 meters (112.6 feet) and a wing area of 124.6 square meters (1341.0 square feet) contribute to the aircraft's aerodynamic performance. Equipped with powerful engines providing a total maximum thrust of 252.0 kN (56,800 lbf), the 737-900ER is well-suited for extended range operations, further enhancing its versatility for various route profiles. With a fuel capacity of 29,700 liters (7,846 US gallons), the aircraft achieves a range of approximately 5,900 kilometers (3,186 nautical miles), enabling it to operate longer routes previously beyond the reach of standard single-aisle aircraft.

The interior of the 737-900ER is configured to accommodate up to 180 passengers in a typical two-class setting, with the capability to seat up to 215 passengers in a denser, single-class arrangement. This flexibility makes the 737-900ER an adaptable solution for airlines to cater to different market demands. The cabin design focuses on enhancing passenger comfort, integrating modern amenities and spacious seating arrangements.

In the competitive landscape of commercial aviation, the 737-900ER stands out as a cost-effective option for airlines to service a wide spectrum of domestic and international routes. Operators such as Alaska Airlines, Delta Air Lines, and United Airlines have integrated the 737-900ER into their fleets, utilizing its operational efficiency and capacity to bolster and diversify their route networks.
