A Dassault vs Gulfstream showdown in the heavy jet class. The Dassault Falcon 900LX carries 12–14 passengers with 4,750 nm of range; the Gulfstream G450 carries 14 with 4,350 nm. Cabin dimensions land at 6'2" × 7'8" versus 6'2" × 7'4", and runway numbers read 5,360 ft against 5,600 ft. Both sit in the same pricing class: an estimated €4,900–€6,500 per flight hour.
DASSAULT
The Dassault Falcon 900LX is the only heavy-jet trijet in production — three Honeywell engines for unmatched redundancy, ETOPS-free transatlantic capability and 4,750 nm of range with twelve passengers in three living zones.

EXPERT VERDICT
The Falcon 900LX pulls ahead on range / non-stop reach, cabin comfort and airport access; the G450 answers with speed & block time. Both sit in the heavy jet class, so charter pricing is broadly aligned — let the use case (range, group size, airport pair) drive the final call.
Range / non-stop reach
Falcon 900LX
4,750 nm of range — the better choice for transcontinental and intercontinental missions.
Cabin comfort
Falcon 900LX
Taller and/or wider cabin (6'2" × 7'8") — better for long flights and stand-up movement.
Group capacity
Even
Matched specifications.
Airport access
Falcon 900LX
Shorter 5,360 ft balanced-field requirement — opens up restricted alpine, island and city-adjacent airfields.
Speed & block time
G450
Cruise of Mach 0.88 — shaves meaningful minutes off every long leg.

FAQ
The Dassault Falcon 900LX has a published range of 4,750 nm; the Gulfstream G450 is rated at 4,350 nm. The longer-range aircraft opens up more non-stop city pairs without a tech stop.
Cruise speeds are Mach 0.87 for the Dassault Falcon 900LX and Mach 0.88 for the Gulfstream G450. The difference in block time grows with trip length; on a London → Mumbai trip it is usually minutes rather than hours.
The Dassault Falcon 900LX seats 12–14; the Gulfstream G450 seats 14. 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 900LX at an estimated €4,900–€6,500 per flight hour, and the Gulfstream G450 at an estimated €4,900–€6,500 per flight hour. These are estimates; the confirmed quote within 1–2 hours depends on positioning, season and airport fees.
The Dassault Falcon 900LX cabin is 6'2" high and 7'8" wide; the Gulfstream G450 is 6'2" high and 7'4" wide. Baggage: 127 cu ft vs 169 cu ft.
For trips within the Gulfstream G450's published 4,350 nm, either aircraft can fly non-stop and the choice comes down to cabin (6'2" vs 6'2" cabin height), seats (12–14 vs 14) and price. Beyond that, the Dassault Falcon 900LX (4,750 nm) flies non-stop where the Gulfstream G450 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 Heavy Jet 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 900LX and Gulfstream G450 sit in the Heavy Jet 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.
