Gulfstream G150: The Complete Buyer's Guide
The Short Version
The Gulfstream G150 is the entry point into the Gulfstream family — and the predecessor to the G280. Produced from 2002 to 2018, it carries 6-8 passengers across 3,000 nautical miles at Mach 0.81 cruise. Pre-owned examples range from $3M to $8M depending on year and total time. The G150 offers genuine Gulfstream prestige and performance at a midsize acquisition price, with the lowest cabin altitude in its class at just 4,350 ft.

What Makes the G150 Different
1. Lowest cabin altitude in its class
At 45,000 ft cruising altitude, the G150 maintains a cabin altitude of just 4,350 ft — lower than any competitor in the super-midsize class. This means passengers arrive feeling more refreshed on 5-7 hour legs. The low cabin altitude is a genuine Gulfstream engineering achievement and one of the aircraft's core selling points.
2. Gulfstream prestige at midsize prices
The G150 offers a genuine Gulfstream ownership experience — the brand, the support network, the resale values — at an acquisition price that overlaps with much smaller light jets. For operators who want the Gulfstream name and the low cabin altitude but find G550/G650ER prices out of reach, the G150 is the logical entry point.
3. Simple, proven platform
The Rolls-Royce AE3007C engines are the same core engine family powering the G200 and a range of regional jets. The platform is mature and well-understood by every Gulfstream-authorized service center. The Gulfstream PlaneView-derived avionics suite is conventional and reliable. Maintenance costs are predictable for enrolled aircraft.
Who Is This Aircraft For?
- ●Buyers stepping up from light or super-light jets who want Gulfstream prestige and low cabin altitude at a sub-$10M acquisition price.
- ●Private operators running 3-5 hour regional missions — New York to Miami, London to Dubai (with a fuel stop), Istanbul to New York — where the G150 covers the mission at a fraction of G550/G650ER operating costs.
- ●Flight departments that want Gulfstream brand recognition, strong resale values, and the lowest cabin altitude in the super-midsize class.
- ●Charter operators looking for a Gulfstream-branded aircraft with strong charter appeal for regional routes.
When It's Not the Right Fit
- ●If your regular missions are over 4,000 NM, the G150 3,000 NM ceiling requires fuel stops. Look at the G280 (3,600 NM) or a larger Gulfstream for those missions.
- ●Buyers who want the latest avionics and cabin technology should look at the G280 or G500. The G150 flight deck is showing its age compared to newer Gulfstream models.

The Pre-Owned Market Right Now
Market research reviewed October 8, 2026. Figures below retain their source dates and measurement basis.
Dated market benchmark, reviewed October 8, 2026: Duncan Aviation's July 2026 guide gives G150 Vref valuations of $2.95M–$6.99M across its listed vintages. This is a model-wide valuation reference, not a reported transaction range or a current seller quote; the upper end for an in-production type can include very new aircraft.
The G150's acquisition band is well below the G280's current advertised market. The lower purchase budget should be assessed alongside maintenance position and the aircraft's ability to cover the buyer's actual midsize mission.
What to Watch For When Buying
1. Rolls-Royce AE3007C engine condition
The AE3007C engines are reliable but require specific maintenance attention. Verify engine LLP status, time since last HSI, and trend monitoring history. Rolls-RoyceCare program enrollment provides cost predictability and should be confirmed at purchase. Aircraft approaching major engine events without program coverage represent significant hidden liabilities.
2. Avionics and ADS-B Out
The Gulfstream PlaneView-derived avionics suite (based on Honeywell Primus Epic) is mature but showing its age. ADS-B Out compliance should be verified before closing. The upgrade path is available but requires investigation of the specific configuration.
3. Original interior condition
Original G150 interiors from the 2002-2010 era are now 15-25 years old. Soft goods, IFE, and cabin materials show their age. A full interior refurbishment runs $200K-$400K. Verify the interior age and condition carefully before closing.
4. High-utilization fleet history
Many G150s have been operated in charter and fractional fleet roles at 500+ hours per year. High-utilization aircraft show accelerated wear on landing gear, thrust reversers, and high-cycle components. Review the logbooks for utilization patterns. A well-maintained private aircraft is worth a meaningful premium.
5. Maintenance program enrollment
Gulfstream's own maintenance programs and CAMP by Conklin & de Decker are both commonly used for G150 aircraft. Full program enrollment is an important indicator of maintenance quality. Aircraft with complete maintenance records and consistent program enrollment are more predictable to own and easier to sell.
6. Pre-purchase inspection essential
A thorough pre-purchase inspection at a Gulfstream-authorized facility is mandatory for a G150 purchase. Budget $35K-$55K for the inspection. Focus on engine borescope, structural elements, and avionics functionality. Given the aircraft's age, finding a qualified inspector with G150-specific experience is important.
G150 vs. The Competition
| Aircraft | Range | Max Speed | Cabin W | Cabin L | Pax | New Price | Pre-Owned |
|---|---|---|---|---|---|---|---|
| Gulfstream G280 | 3,600 NM | Mach 0.85 | 7 ft 1 in | 22 ft 4 in | 8-10 | ~$22M (historical) | ~$8M (historical) |
| Bombardier Challenger 300 | 3,065 NM | Mach 0.82 | 7 ft 2 in | 28 ft 4 in | 8-10 | ~$21M (historical) | ~$8M (historical) |

Gulfstream G280
Bombardier Challenger 300
Cessna Citation Latitude
vs. Gulfstream G280
The G280 is the G150 successor with a longer cabin (22 ft vs 14 ft), more range (3,600 vs 3,000 NM), and updated Honeywell avionics. Pre-owned G280 examples overlap with late-model G150 pricing. The G150 wins on acquisition price; the G280 wins on every capability metric. If the budget allows, the G280 is the better aircraft.
vs. Bombardier Challenger 300
The Challenger 300 has a wider cabin (7 ft 2 in vs 6 ft 2 in), more range (3,065 vs 3,000 NM), and a larger parts network. Pre-owned Challengers from $8M overlap with late-model G150 pricing. The G150 wins on cabin altitude (4,350 ft vs 6,000+ ft) and Gulfstream brand; the Challenger wins on cabin width and parts network size.
vs. Cessna Citation Latitude
The Citation Latitude has a longer cabin and similar range to the G150 (2,700 vs 3,000 NM), but at a higher acquisition price ($9M vs $5M-$8M for a G150). The G150 wins on Gulfstream brand, cabin altitude, and acquisition price. The Latitude wins on Cessna service network and pre-owned availability.

4,350 ft at 45,000 ft cruising altitude — the lowest in the super-midsize class. By comparison, the Challenger 300 maintains approximately 6,000 ft and the Citation Latitude maintains 5,950 ft at altitude. The lower cabin altitude means passengers experience less fatigue on long legs.
The G280 has a longer cabin (22 ft vs 14 ft), more range (3,600 vs 3,000 NM), updated Honeywell Primus Epic avionics, and winglets. The G150 is the more affordable option; the G280 is the upgrade path.
No. Gulfstream ended G150 production in 2018, replacing it with the G280. The platform is well-supported through Gulfstream and authorized service centers worldwide. Parts availability is strong.
