What is the Gulfstream G450 / G350?
The Gulfstream G450 is a large-cabin twin-engine business jet. It is the last version of the Gulfstream IV family, with the forward fuselage and PlaneView flight deck of the G550. Gulfstream delivered the first in 2004 and the last in January 2018, after more than 360 were built. Most seat 12 to 16 in three zones and fly about 4,350 nm non-stop. The G350 is the same aircraft with less fuel and a shorter range.
4,350 nm of range at Mach 0.80 with 8 passengers and NBAA IFR reserves.
Two Rolls-Royce Tay 611-8C engines of 13,850 lb thrust each, with FADEC.
Cabin 40 ft 4 in (12.29 m) long, 7 ft 4 in (2.24 m) wide and 6 ft 2 in (1.88 m) tall, with a 169 cu ft hold reachable in flight.
PlaneView flight deck with a head-up display and enhanced vision as standard on the G450.
104 fly with 29 operators on the FAA Part 135 list, the largest G450 charter fleet anywhere. Altivo Jets books them through these certified operators.

Fuel burn and CO2
The G450 burns about 517 US gallons (1,565 kg) of jet fuel an hour, which puts out about 4.9 tonnes of CO2. Sustainable aviation fuel, where the departure airport has it, cuts the lifecycle figure.
| Flight | Fuel | CO2 |
|---|---|---|
| 1 flight hour | 1,570 kg | 4.9 tonnes |
| 3 flight hours | 4,700 kg | 14.8 tonnes |
| 8 flight hours | 12,520 kg | 39.6 tonnes |
Average block figures; real burn depends on weight, altitude and winds. Fuel at 0.8 kg per litre.

How much does a G450 cost?
A new G450 listed at about $43 million in 2004. Production has ended, so most buyers look at pre-owned aircraft. Owning one also means paying to fly and maintain it, which is why most people who fly a few times a year charter instead.
Buy new
List price of a new G450 when deliveries began, as reported by CRAFT; Business Jet Traveler also gives $43 million new.
Buy pre-owned
Asking prices, not valuations: Guardian Jet tracked 19 G450s for sale, asking $8.495 million to $19.495 million, model years 2005 to 2014. October 2026.
Cost to operate
Total cost per flight hour including fixed costs at 200 hours a year, CRAFT G450 ownership and operating cost estimate (annual total $2,643,567, fuel at $7.66 a gallon, October 2026). Fuel burn about 517 US gallons an hour.

G450 charter cost per hour in the US (2026)
You pay for flight time, not the aircraft. Heavy jets like the G450 charter at about $15.1k to $18.5k per flight hour; the quote adds positioning, crew overnights, airport charges and taxes for your exact trip.
Heavy jets, per flight hour
What moves the price
- Positioning: one-way trips usually pay for the empty flight home.
- Crew overnights and waiting days on multi-day trips.
- Airport and handling fees, plus federal excise tax.
- Empty legs can cut the price sharply when one matches your dates.
Charter or own?
Owning a G450 costs about $1.08 million a year before it flies (crew, hangar, insurance), plus about $7,800 for every flight hour. At the hours most owners fly, chartering costs less per hour, and you pay nothing when you do not fly.
| You fly | Owning (per hour) | Charter in the US (per hour) |
|---|---|---|
| 50 hours a year | $29,400 per hour | $15.1k to $18.5k per hour |
| 100 hours a year | $18,600 per hour | $15.1k to $18.5k per hour |
| 200 hours a year | $13,200 per hour | $15.1k to $18.5k per hour |
| 300 hours a year | $11,400 per hour | $15.1k to $18.5k per hour |
CRAFT Gulfstream G450 ownership and operating cost estimate (October 2026): crew, training, hangar, insurance, management and other fixed costs a year, plus fuel at $7.66 a gallon (517 gallons an hour), maintenance, engine overhaul reserves and trip costs per flight hour, for an aircraft flying 200 hours a year. Excludes buying the aircraft and depreciation. Charter rates are before taxes, positioning and airport charges.

Where the G450 can land
A 4,350 nm jet that needs about 5,600 ft of runway at full weight, and less on shorter trips.
Runway needed
About 5,600 ft to take off at maximum weight at sea level and about 2,663 ft to land at maximum landing weight. Hot or high airports need more. Aviation Week notes that the G450 has no leading-edge slats, so the Falcon 900EX and Global 5000 do better on short runways.
Low visibility
EASA approved landing credit for Gulfstreams with the head-up display and enhanced vision, so crews can descend to a 100 ft decision height on some approaches with operator approval. Enhanced vision is standard on the G450 and was optional on the G350.

G450
The GIV-X, FAA approved on 12 August 2004. It gained the G550 forward fuselage and PlaneView flight deck, Tay 611-8C engines with FADEC and redesigned thrust reversers, and about 200 nm more range than the GIV-SP. The last was delivered on 19 January 2018.
G350
The same GIV-X airframe with less fuel: 25,895 lb usable against 29,500 lb for the G450, and a maximum takeoff weight of 70,900 lb. Range is about 3,800 nm, and enhanced vision was optional.
G450 vs G550
- Range: 4,350 nm for the G450 against 6,750 nm for the G550, which flies 2,400 nm further.
- Cabin: the same 7 ft 4 in width and 6 ft 2 in height, but the G550 cabin is 43 ft 11 in long and 1,669 cu ft, 3 ft 7 in longer than the G450.
- Engines: two Rolls-Royce Tay 611-8C on the G450, against two Rolls-Royce BR710 on the G550.
- Weight: 74,600 lb maximum takeoff weight for the G450, against 91,000 lb for the G550.
- Altitude: the G450 is certified to 45,000 ft and the G550 to 51,000 ft.
- Runway: 5,600 ft to take off at maximum weight, against 5,910 ft for the G550.

Gold marks the best figure in each row. Take-off distance: At maximum take-off weight, sea level. Cabin length: Manufacturers measure cabin length differently; volume is the fairer comparison. Operating cost per hour: As reported; some sources quote variable cost only, others include fixed costs. See the basis under each aircraft.

G450 safety record
Events from official investigations and safety databases. We also check the record of the exact aircraft and operator before we book.
N667HS, Salzburg, 2017
The landing gear of a G450 would not retract after takeoff because its safety pins were still fitted, and the crew returned to Salzburg. While the copilot was removing the pins on a taxiway, the nose gear collapsed. No one was hurt. Austria's investigators cited an incomplete preflight check and unfamiliarity with the gear checklists.
HZ-A23, Jeddah, 2022
A G450 veered off runway 34L after landing at Jeddah. No one of the five on board was killed, but the gear was torn off or collapsed and the aircraft was written off.
Type record

Questions, answered
Still deciding? A charter specialist will talk you through aircraft, airports and price, with no obligation.
Ask a specialistHow much does a Gulfstream G450 cost?+
A new G450 listed at about $43 million when deliveries began. Used asking prices in October 2026 ran from about $8.5 million to about $19.5 million. CRAFT estimates about $1.08 million a year in fixed costs plus about $7,835 per flight hour to run one.
How many passengers does a G450 seat?+
Typically 14, and up to 16 in most layouts. The type is certified for up to 19 passenger seats.
How far can a Gulfstream G450 fly?+
About 4,350 nm at Mach 0.80 with 8 passengers and NBAA IFR reserves. At Mach 0.85 range falls to about 3,300 nm.
What is the difference between the G450 and the G550?+
They share the same cabin cross section and flight deck, but the G550 is longer, heavier and has BR710 engines. It flies about 6,750 nm against 4,350 nm, and its cabin is 3 ft 7 in longer.
What is the difference between the G350 and the G450?+
Both are the GIV-X. The G350 carries less fuel, 25,895 lb usable against 29,500 lb, and has a lower maximum takeoff weight, so it flies about 3,800 nm instead of 4,350 nm.
Is the Gulfstream G450 still in production?+
No. Gulfstream ended the line to make way for the G500 and delivered the last G450 on 19 January 2018.
How much fuel does a G450 burn per hour?+
CRAFT puts the average at 517 US gallons an hour.
Who operates the Gulfstream G450 / G350 in the US?+
29 FAA Part 135 operators fly 104 of them. The largest fleets: Flexjet (32), Executive Jet Management (16), Solairus Aviation (12), Vista America (6) and Thrive Aviation (5).
How much does it cost to charter a G450?+
About $15.1k to $18.5k per flight hour, before federal excise tax, positioning and airport charges. A one-way trip is priced on flight hours plus the aircraft's return positioning, so ask for a quote on your dates.
