The Gulfstream III is the large-group heavy jet of the Palm Beach charter market, seating fourteen to nineteen people in a cabin that later Gulfstreams inherited. Roughly 3,650 nautical miles of range covers the domestic corridors and the Caribbean with the cabin full. When the passenger count climbs past what a Challenger or Falcon will take, this is usually the next aircraft on the list.
Gulfstream built the III on the II airframe with a redesigned wing, winglets and a longer fuselage, retaining Rolls-Royce Spey 511-8 turbofans. It seats fourteen to nineteen depending on layout, cruises at about 442 knots and flies roughly 3,650 nautical miles. It is a legacy airframe, and interiors and avionics vary substantially between individual aircraft. Full specifications for the Gulfstream III / G3 are published by Gulfstream Aerospace.

Why the Gulfstream III / G3 Fits Palm Beach
Wedding parties, charity delegations and sports groups traveling out of Palm Beach County regularly land in the fourteen to nineteen passenger band, which is exactly where the Gulfstream III sits. Above nineteen passengers the trip moves into airliner-size aircraft operating under FAR Part 121 or the foreign equivalent, which is a different conversation and a different quote.
Season arrivals for large extended families work on this aircraft. Teterboro (KTEB), Hanscom (KBED) and Chicago (KMDW) are all comfortable legs with every seat taken and the baggage hold full.
Group travel to the Caribbean is the other regular job: Nassau (MYNN), Providenciales (MBPV) and Grand Cayman (MWCR) with a full cabin. As with any legacy Gulfstream, we confirm the operator’s certification and safety history, confirm the pilots are current on the type, and describe the cabin condition honestly before you book.

Vetting Behind Every Trip
Every operator, aircraft, and crew goes through our internal due diligence before we present any options. Our internal standards meet or exceed what the FAA requires:
- FAR Part 135 charter operators for traditional private aircraft, or FAR Part 121 for airliner-size and group trips (or the foreign equivalent on international legs)
- 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.
