The Gulfstream III took the Gulfstream II’s cabin and gave it a proper wing, and it remains a value route into large-cabin charter from Los Angeles. Fourteen to nineteen seats, 3,650 nautical miles, and the distinctive winglets that mark the generation.
Gulfstream redesigned the II’s wing with winglets and a lengthened fuselage to create the III, keeping the Rolls-Royce Spey engines. Fourteen to nineteen seats, 442 knots and 3,650 nautical miles of range. Full specifications for the Gulfstream III / G3 are published by Gulfstream Aerospace.

Why the Gulfstream III / G3 Fits Los Angeles
Nineteen seats is the highest count in this category and it puts the Gulfstream III into a specific Los Angeles niche: large groups that do not need airliner capacity but have outgrown a Challenger. Touring parties and sports squads are the regular users.
The winglets and the new wing add 450 nautical miles over the Gulfstream II, which from Los Angeles means the East Coast is reachable with a working payload rather than a hopeful one.
It carries the same Spey engines as the II and the same noise profile, so the curfew and slot considerations at Van Nuys and Long Beach apply equally. Ontario, running 24 hours with no curfew, is often the cleaner answer for a late departure.

- Operator subscription to Wyvern and ARGUS reviewed where the operator participates.
- Pilot experience and operator incident history reviewed before we recommend an aircraft.
- Fewer than 60 brokers worldwide hold Premium Wyvern Broker Member status, and Air Charter Advisors is one of them.
