Charter a Gulfstream G400

The Gulfstream G400 - also known as the GIV or G-IV - is one of the most successful large-cabin business jets ever built, developed from the Gulfstream III with a redesigned wing for improved aerodynamics, a stretched fuselage for greater range and an increased maximum takeoff weight that expands payload and flexibility. First delivered in 1985 and continuously refined through the G400 designation, it has accumulated decades of operational experience and enjoys a reputation among operators as one of the most reliable aircraft in the large-cabin category. Gulfstream's technical support for the type is cited consistently as first-class. The cabin at 12.29 m long, 2.24 m wide and 1.88 m high carries up to 12 passengers and is divided into two functional zones with transformer furniture that serves both productive work and relaxed travel.

With a range of 4,100 nm (7,600 km) and a cruise speed of 920 km/h - among the highest in its category - the G400 covers London to New York non-stop, London to Dubai comfortably non-stop and reaches Sub-Saharan Africa with one efficient fuel stop. The enhanced maximum takeoff weight versus the earlier GIV opens more airports on longer missions by allowing landing at higher weights without requiring a fuel stop to reduce weight. An infrared vision system provides pilot situational awareness in low-visibility conditions. Charter prices start from approximately £4,500 per flight hour.

Why charter the G400?

• One of the most reliable large-cabin jets in charter service. Operators consistently rank it among the most dependable aircraft in their fleets. Decades of production and service have produced a well-understood maintenance profile and a worldwide service network. Gulfstream's technical support for the type is cited across the industry as exceptional;
• 920 km/h cruise speed. The G400 cruises at 920 km/h - faster than the Challenger 605 (850 km/h), the Legacy 650 (828 km/h) and many competing large-cabin jets. On a 7-hour transatlantic sector the speed advantage over a 850 km/h competitor translates to approximately 45 to 60 minutes of saved flight time;
• 4,100 nm range covering New York and the Gulf non-stop. The range handles London to New York non-stop, London to Dubai and the full Gulf non-stop and reaches East Africa with one fuel stop. The increased maximum landing weight versus the earlier GIV variant extends the airport options available on longer missions;
• Infrared vision system. The G400 avionics suite includes an infrared vision system that enhances pilot situational awareness in low-visibility conditions - fog, haze, night operations - providing a safety margin not standard on most competing large-cabin jets at this charter rate;
• Two-zone cabin with transformer furniture. The 12.29 m cabin is divided into two functional zones with convertible furniture designed for both business and leisure configurations. Comfortable chairs in a meeting setup convert to positions suitable for rest on longer sectors;
• Best-in-class Gulfstream noise isolation. The modern soundproofing system reduces cabin noise to levels consistently praised by passengers - a characteristic of the Gulfstream family that sets it apart from other large-cabin alternatives at comparable charter rates.

Charter cost - G400 prices from UK airports

Hourly rates run from approximately £4,500 to £5,400 - above the G300 and broadly positioned against the Challenger 605 and Legacy 650. On transatlantic and Gulf sectors where the G400's higher cruise speed saves 45 to 60 minutes versus slower alternatives, the rate premium is partially offset by the reduced sector time.

Indicative one-way prices from UK airports:

• London to New York - from £40,000 (8 passengers, non-stop, approximately 7 hours 10 minutes);
• London to Dubai - from £30,000 (8 passengers, non-stop, approximately 6 hours 30 minutes);
• London to Geneva - from £8,600 (8 passengers, approximately 1 hour 20 minutes);
• London to Athens - from £18,400 (8 passengers, approximately 3 hours 20 minutes);
• London to Nairobi - from £42,000 (8 passengers, one fuel stop, approximately 9 hours total);
• Edinburgh to Istanbul - from £19,000 (8 passengers, approximately 3 hours 30 minutes);
• Manchester to Riyadh - from £28,000 (8 passengers, non-stop, approximately 6 hours).

Ideal routes for the G400

It is most compelling on missions where the Gulfstream cabin standard, long range and high cruise speed combine to deliver a materially better experience than lower-cost alternatives:

• Transatlantic non-stop (New York, Boston, Miami) - 7 to 8.5 hours. The G400's 920 km/h cruise speed and 4,100 nm range make it one of the faster large-cabin options on this sector. For 8 passengers crossing the Atlantic where speed and cabin quality are the priorities, it competes directly with the Challenger 605 and Legacy 650 at comparable rates but with a meaningful speed advantage;
• UK to Gulf non-stop (6 to 7 hours). Dubai, Riyadh, Abu Dhabi, Doha and Kuwait City are all within non-stop range from UK airports. The two-zone cabin and noise isolation are well matched to 6 to 7 hour working sectors. The higher cruise speed delivers Dubai approximately 40 minutes faster than a Challenger 605 on the same routing;
• UK to East Africa (one fuel stop). Nairobi, Dar es Salaam, Addis Ababa with one fuel stop from UK airports. The infrared vision system provides an operational safety advantage for arrivals at African airports with variable infrastructure and lighting standards;
• Large group European travel (2 to 4 hours). For groups of 8 to 12 passengers on European sectors, the G400's 12.29 m large cabin provides the Gulfstream experience - noise isolation, transformer furniture, two zones - at rates competitive with the Challenger 605 and Legacy 650;
• Reliability-critical missions. Corporate flight departments and frequent charter clients who specifically prioritise operational reliability and cite it as a primary selection criterion choose the G400 for the consistency of Gulfstream's technical support network and the type's long service record.

Cabin and in-flight experience

This aircraft cabin measures 12.29 m long, 2.24 m wide and 1.88 m high - standing headroom throughout.

Technical specifications

G400 vs similar aircraft

• G400 vs Challenger 605. The 605 has a wider cabin (2.49 m vs 2.24 m) and comparable range (4,000 nm vs 4,100 nm). Charter rates are broadly similar. The G400 counters with a higher cruise speed (920 km/h vs 850 km/h) and the infrared vision system. On a 7-hour transatlantic sector the G400's speed advantage is approximately 50 minutes. For clients who prioritise cabin width, the 605 is the stronger choice; for those who value speed and the Gulfstream family cabin standard, the G400 is preferable;
• G400 vs Legacy 650. The 650 has more range (3,900 nm vs 4,100 nm - broadly comparable), a longer cabin (12.93 m vs 12.29 m) and six sleeping positions. Charter rates are broadly similar. The G400 advantage is higher cruise speed (920 km/h vs 828 km/h) - approximately 60 to 70 minutes faster on a transatlantic sector. For clients where speed is the priority, the G400 is the clear choice; for those who need six sleeping positions, the Legacy 650 has a structural advantage;
• G400 vs G300. The G300 is the predecessor with similar cabin dimensions and Rolls-Royce Tay engines but lower cruise speed and a shorter production run. Charter rates for the G300 run approximately 10 to 20% lower. For clients who specifically want the latest G400 avionics including the infrared vision system, this is the necessary choice; for those comfortable with the G300's capabilities on missions within its range, the earlier variant offers a cost saving.
