Two Gulfstream heavy jets from the same stable, compared where it counts. The Gulfstream G450 carries 14 passengers with 4,350 nm of range; the Gulfstream GIV-SP carries 14 with 4,220 nm. Cabin dimensions land at 6'2" × 7'4" versus 6'2" × 7'4", and runway numbers read 5,600 ft against 5,450 ft. Both sit in the same pricing class: an estimated €4,900–€6,500 per flight hour.
GULFSTREAM
The Gulfstream G450 delivers full transatlantic capability and the unmistakable Gulfstream cabin experience at heavy-jet pricing. 4,350 nm of range puts London–New York, Dubai–London and coast-to-coast US nonstop within easy reach for up to 14 passengers.

The Gulfstream GIV-SP defined the intercontinental heavy-jet segment — Rolls-Royce Tay engines, three living areas and 4,220 nm of nonstop range. Still a workhorse of the global charter fleet.

FAQ
The Gulfstream G450 has a published range of 4,350 nm; the Gulfstream GIV-SP is rated at 4,220 nm. The longer-range aircraft opens up more non-stop city pairs without a tech stop.
Cruise speeds are Mach 0.88 for the Gulfstream G450 and Mach 0.80 for the Gulfstream GIV-SP. The difference in block time grows with trip length; on a London → New York trip it is usually minutes rather than hours.
The Gulfstream G450 seats 14; the Gulfstream GIV-SP 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 Gulfstream G450 at an estimated €4,900–€6,500 per flight hour, and the Gulfstream GIV-SP 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 Gulfstream G450 cabin is 6'2" high and 7'4" wide; the Gulfstream GIV-SP is 6'2" high and 7'4" wide. Baggage: 169 cu ft vs 169 cu ft.
For trips within the Gulfstream GIV-SP's published 4,220 nm, either aircraft can fly non-stop and the choice comes down to cabin (6'2" vs 6'2" cabin height), seats (14 vs 14) and price. Beyond that, the Gulfstream G450 (4,350 nm) flies non-stop where the Gulfstream GIV-SP 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 Gulfstream G450 and Gulfstream GIV-SP 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.
