The Gulfstream III / G3 is a classic large-cabin Puerto Rico heavy jet from San Juan (SJU), seating 14 to 19 with 3,650 nautical miles of range. It covers SJU to the full US mainland or northern South America nonstop in a stand-up cabin. An early large-cabin Gulfstream still flown in charter.
Gulfstream built the GIII from 1980 with winglets and a longer cabin than the GII, cruising near 442 knots at up to 45,000 feet. It carried the large-cabin Gulfstream line forward in its era.

For clients weighing budget and space out of SJU, the GIII offers heavy-jet room on a well-supported airframe.
