Challenger 605 vs Falcon 900LX
The Falcon 900LX leads, topping 5 of 7 compared metrics.

- The Falcon 900LX is the newer design (introduced 2010 versus 2006 for the Challenger 605), a gap of 4 years that usually shows up in avionics, cabin systems and fuel burn.
- The Falcon 900LX is the larger aircraft by maximum takeoff weight (49,000 lbs versus 48,300 lbs), which typically buys more cabin and payload at the cost of higher trip economics.

Which mission suits which aircraft
Both aircraft are built for long-haul and transatlantic missions, so outright range rarely separates them — the call leans on cabin (the Falcon 900LX seats more), trip economics and what is actually available on the market. Match the airframe to how you fly most weeks, not to the headline range figure.
Which should you choose?
On published specifications the Falcon 900LX leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The Challenger 605 can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
