For Houston departures to Europe, South America, or the West Coast with a full group, a heavy jet is the practical starting point. The Gulfstream III / G3 is one of the larger cabins we put in front of Houston groups before the trip moves to airliner-size.
Gulfstream Aerospace introduced the Gulfstream III / G3 in 1980.

Why the Gulfstream III / G3 Fits Houston
Hobby and Bush Intercontinental both take it without qualification, and it carries a full group with baggage on a long sector.
The published 3,650 nautical miles covers New York, Bogota, and Sao Paulo nonstop out of Houston once you allow for winds and reserves. How much you are carrying and what the winds are doing will move that, which the operator calculates per trip.

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; reports may be provided on request.
- 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.
