Citation Longitude vs G400
The G400 leads, topping 5 of 7 compared metrics.
The Cessna / Textron Aviation Citation Longitude (introduced 2019) and the Gulfstream Aerospace G400 (introduced 2023) are two aircraft buyers regularly weigh against each other. Both are business jets, which makes them natural cross-shopping rivals. The clearest separation between them is cabin capacity, where the G400 carries more passengers. undefined

Citation Longitude vs G400: the key differences
- The G400 delivers 20% more range (Citation Longitude: 3,500 nm; G400: 4,200 nm).

- The G400 delivers 58% more passenger capacity (Citation Longitude: 12 seats; G400: 19 seats).
- The G400 is the newer design (introduced 2023 versus 2019 for the Citation Longitude), a gap of 4 years that usually shows up in avionics, cabin systems and fuel burn.
- The G400 is the larger aircraft by maximum takeoff weight (74,600 lbs versus 44,000 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 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?
On published specifications the G400 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.
