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 G400 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?
Choose the Falcon 6X when nonstop range is the deciding factor, and the G400 when cabin capacity and payload matter more; the Falcon 6X holds the cruise-speed edge. The right answer ultimately depends on acquisition cost, maintenance-program status, and what is actually available on the market — talk to our acquisition advisory team to pressure-test the choice against your missions and budget.
