About the Bombardier (Canadair) Challenger 300

The Bombardier Challenger 300 redefined the super-midsize business jet category when it entered service in 2004, combining transcontinental range with a wide-body cabin cross-section previously reserved for larger aircraft. Developed as a clean-sheet design rather than a derivative, the CL-300 introduced a supercritical wing optimized for high-speed cruise and a flat floor cabin that seats up to nine passengers in exceptional comfort. Its 3,100 nautical mile range opened nonstop city pairs like New York to Los Angeles or London to Dubai, while the wide fuselage allowed stand-up headroom and a genuine feeling of space uncommon in its class.

Powered by twin Honeywell HTF7000 turbofans, the Challenger 300 cruises at Mach 0.80 and can reach a maximum operating speed of Mach 0.83 at altitudes up to 45,000 feet. The type became the foundation for Bombardier's super-midsize family, spawning the improved Challenger 350 in 2014 while the original 300 remained in production until 2015. Its combination of cabin width, range, and speed made it a favorite among fractional ownership operators and corporate flight departments seeking airline-like comfort without the operating costs of a heavy jet.

The Challenger 300's success cemented Bombardier's position in the competitive business aviation market and set new benchmarks for passenger experience in its segment. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
