A Dassault vs Gulfstream showdown in the ultra long range class. The Dassault Falcon 6X carries 12–16 passengers with 5,500 nm of range; the Gulfstream G800 carries 13–19 with 8,200 nm. Cabin dimensions land at 6'6" × 8'6" versus 6'3" × 8'2", and runway numbers read 5,480 ft against 5,812 ft. Both sit in the same pricing class: an estimated €7,100–€9,600 per flight hour.

EXPERT VERDICT
The Falcon 6X pulls ahead on cabin comfort and airport access; the G800 answers with range / non-stop reach, group capacity and speed & block time. Both sit in the ultra long range class, so charter pricing is broadly aligned — let the use case (range, group size, airport pair) drive the final call.
Range / non-stop reach
G800
8,200 nm of range — the better choice for transcontinental and intercontinental missions.
Cabin comfort
Falcon 6X
Taller and/or wider cabin (6'6" × 8'6") — better for long flights and stand-up movement.
Group capacity
G800
Seats up to 19 — the right pick when the manifest grows.
Airport access
Falcon 6X
Shorter 5,480 ft balanced-field requirement — opens up restricted alpine, island and city-adjacent airfields.
Speed & block time
G800
Maximum operating speed Mach 0.935 — shaves meaningful minutes off every long leg.
Verdict based on published manufacturer specifications, charter market data and Limitless Sky brokerage experience.

| ROUTE | DISTANCE | RECOMMENDED | WHY |
|---|---|---|---|
| London → Singapore | 5,900 nm | G800 | Only one reaches non-stop — the other would need a fuel stop (5900 nm > 5,500 nm). |
| New York → Tokyo | 5,850 nm | G800 | Only one reaches non-stop — the other would need a fuel stop (5850 nm > 5,500 nm). |
| Dubai → Los Angeles | 7,250 nm | G800 | Only one reaches non-stop — the other would need a fuel stop (7250 nm > 5,500 nm). |
| Hong Kong → New York | 7,000 nm | G800 | Only one reaches non-stop — the other would need a fuel stop (7000 nm > 5,500 nm). |

FAQ
The Dassault Falcon 6X has a published range of 5,500 nm; the Gulfstream G800 is rated at 8,200 nm. The longer-range aircraft opens up more non-stop city pairs without a tech stop.
Cruise speeds are Mach 0.85 for the Dassault Falcon 6X and Mach 0.935 for the Gulfstream G800. The difference in block time grows with trip length; on a Teterboro → Dubai trip it is usually minutes rather than hours.
The Dassault Falcon 6X seats 12–16; the Gulfstream G800 seats 13–19. Charter prices below assume a typical executive layout — high-density configurations are available on request.
From our pricing engine's class rates: the Dassault Falcon 6X at an estimated €7,100–€9,600 per flight hour, and the Gulfstream G800 at an estimated €7,100–€9,600 per flight hour. These are estimates; the confirmed quote within 1–2 hours depends on positioning, season and airport fees.
The Dassault Falcon 6X cabin is 6'6" high and 8'6" wide; the Gulfstream G800 is 6'3" high and 8'2" wide. Baggage: 155 cu ft vs 195 cu ft.
For trips within the Dassault Falcon 6X's published 5,500 nm, either aircraft can fly non-stop and the choice comes down to cabin (6'6" vs 6'3" cabin height), seats (12–16 vs 13–19) and price. Beyond that, the Gulfstream G800 (8,200 nm) flies non-stop where the Dassault Falcon 6X may need a fuel stop. Real-world range drops with passengers, bags, winds and winter reserves, so we confirm it per trip.
Both belong to the Ultra Long Range category, but range, payload and runway performance differ. See the route-recommendations table on this page for our specific pick per corridor.
Cabin comfort is the everyday difference passengers feel most. Both the Dassault Falcon 6X and Gulfstream G800 sit in the Ultra Long Range class, so cabin height, width and layout differ subtly — on flights over 3 hours those details matter more than raw range. Ask us for a side-by-side floorplan.
Both aircraft in this comparison are operated under ARG/US, Wyvern or IS-BAO safety programmes when chartered through Limitless Sky. Safety is driven by operator, crew currency and maintenance regime — not the airframe. We only book operators meeting our verified due-diligence checklist.
The hourly class rate is only one input. Total mission cost includes positioning legs, overnight fees, landing/handling, catering, de-icing and FET where applicable. Our confirmed quote itemises every line so there are no surprises.
