The Gulfstream G550 remains one of the most respected ultra-long-range aircraft in business aviation. Despite being succeeded by newer Gulfstream models, the G550 continues to attract buyers seeking exceptional range, dispatch reliability, and proven performance at a significantly lower acquisition cost. Transaction activity remains healthy, with both retail and off-market sales demonstrating continued confidence in the platform.
Fleet Size and Availability
There are currently 16 Gulfstream G550 aircraft available worldwide, representing just 2.6% of the global fleet.
Inventory has steadily declined throughout much of 2026, falling from 25 aircraft available in January to 15 aircraft in April, before stabilizing at 17 aircraft during May and June. The reduction in available inventory reflects continued demand, while the recent leveling suggests the market has reached a healthy equilibrium between new listings and completed sales.
Market Listings
Current asking prices range from $14.0 million to $34.95 million, highlighting the significant variation in aircraft age, maintenance status, cabin refurbishment, avionics upgrades, and program enrollment across the fleet.
Active listings are averaging 197 days on market, indicating buyers remain selective when evaluating aircraft in this segment. Premium aircraft with comprehensive engine programs, updated interiors, and favorable maintenance pedigree continue to command the strongest interest.
Sales Activity
During the past six months, 32 Gulfstream G550 aircraft sold, including an impressive 16 off-market transactions, representing 5.2% of the worldwide fleet.
Reported transaction prices ranged from $10.25 million to $29.0 million, with completed sales averaging 188 days on market. Sales activity remained remarkably consistent throughout the period and accelerated again in June, when eight aircraft changed hands, underscoring the market’s continued depth and liquidity.
