Which Should You Buy: Gulfstream G550 or Gulfstream G650?

Bottom line: Choose the G550 for proven ultra-long-range capability at a lower entry point — a globally supported, time-tested airframe that still crosses oceans with ease. Choose the G650 for the flagship experience: greater speed, longer range, a larger and quieter cabin and the newest technology, at a clear premium. On safety both are two-crew, ultra-long-range Gulfstreams with excellent records and the redundancy of large twin-jets — the difference is range, speed and cabin, not safety. The G550 is the value path to global range; the G650 is the benchmark the rest of the class chases.

Pick the G550 if…

  • Lower operating cost — ~$5500/hr vs $5800/hr.
  • More inventory — 55 listings vs 18.

Pick the G650 if…

  • More seats — 19 vs 18.
  • Longer range — 7500 nm vs 6750 nm.
  • Newer design — production from 2012 vs 2003.

Frequently Asked Questions

What's the difference between the G550 and G650?
The G650 is newer and more capable — faster, longer-ranged and with a larger, quieter cabin — while the G550 is the proven, longer-serving jet at a lower acquisition cost. Both are ultra-long-range Gulfstreams.
Which has the longer range?
The G650 — it extended Gulfstream's range and speed beyond the G550, with the G650ER reaching even farther. The G550's range is still genuinely intercontinental.
Which is the better value?
The G550 — as the earlier model it carries a lower price for proven global capability. The G650 commands a premium for being the newer flagship.
Which is better, Gulfstream G550 or Gulfstream G650?
It depends on your mission and budget. The G550 cruises at 488 kts with 6,750 nm range. The G650 cruises at 488 kts with 7,500 nm range. Review the specs table above to find which fits your flying profile.
How do prices compare?
Prices vary by year, hours, avionics, and condition. Always get a pre-buy inspection.
What's the difference between Gulfstream G550 and Gulfstream G650?
Seats: 18 vs 19. Cruise: 488 vs 488 kts. Range: 6750 vs 7500 nm.
Which is cheaper to operate per hour?
G550: about $5500/hr variable cost. G650: about $5800/hr variable cost. Variable cost includes fuel, reserves and overhaul accruals. Annual fixed costs (hangar, insurance, annual inspection) add to the total.
Which has more seats and useful load?
G550: 18 seats / 27,500 lb useful load. G650: 19 seats / 30,000 lb useful load. Useful load = max gross weight minus empty weight; it determines how much fuel plus payload you can carry.
How does maintenance compare — TBO and overhaul cost?
G550: 7,000-hour TBO, overhaul ~$1,300,000. G650: 6,000-hour TBO, overhaul ~$900,000. Reaching the time-between-overhaul (TBO) triggers a mandatory engine/airframe rebuild that affects resale value.
