- The Challenger 605 and Citation Longitude are evenly matched on passenger capacity, both at 12 seats.
- The Citation Longitude is the newer design (introduced 2019 versus 2006 for the Challenger 605), a gap of 13 years that usually shows up in avionics, cabin systems and fuel burn.

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 Challenger 605 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 Challenger 605 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The Citation Longitude 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.
