G550 vs G600
G550 and G600 are closely matched, each topping 1 of 7 metrics.
The Gulfstream Aerospace G550 (introduced 2003) and the Gulfstream Aerospace G600 (introduced 2019) are two aircraft buyers regularly weigh against each other. Both are business jets, which makes them natural cross-shopping rivals. On paper they are closely matched, so the decision usually turns on cabin, economics and availability. We line the numbers up below, then translate them into the mission each aircraft actually wins.

G550 vs G600: the key differences
- The G550 delivers 4% more range (G550: 6,750 nm; G600: 6,500 nm).
- The G550 and G600 are evenly matched on cruise speed, both at 488 kt.
- The G550 and G600 are evenly matched on passenger capacity, both at 19 seats.
- The G600 is the newer design (introduced 2019 versus 2003 for the G550), a gap of 16 years that usually shows up in avionics, cabin systems and fuel burn.
- The G600 is the larger aircraft by maximum takeoff weight (99,600 lbs versus 91,000 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 nonstop ultra-long-haul routes, so outright range rarely separates them — the call leans on cabin (the G550 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 G550 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The G600 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.
