The Gulfstream G100, G150 and IAI Astra SPX are a related family of Israeli-built midsize jets, and in the Palm Beach market they sell on speed and range rather than cabin width. At 2,950 nautical miles the G150 has the longest legs of any midsize aircraft on most South Florida quote sheets, which puts Colorado and the southern Caribbean within nonstop reach.
Israel Aerospace Industries developed the Astra SPX, which Gulfstream later marketed as the G100 and then redesigned as the wider-cabin G150. All three seat 6 to 7 passengers behind two Honeywell TFE731 engines at a cruise around 475 knots. The G150’s fuselage cross-section is wider than the G100’s, though the cabin is still narrower than a Hawker or Citation Excel. Full specifications for the Gulfstream G100 / G150 / IAI Astra SPX are published by Gulfstream Aerospace.

Why the Gulfstream G100 / G150 / IAI Astra SPX Fits Palm Beach
Range per dollar is the reason this family stays in the market. West Palm Beach to Aspen at about 1,540 nautical miles, to Denver at about 1,460, to Barbados at about 1,420: all nonstop, all at a midsize rate. For a Palm Beach client with a Colorado house and a midsize budget, that combination is hard to find elsewhere.
The narrow cabin is the honest trade. Six or seven passengers fit, but on a 4-hour leg the aircraft feels tighter than a Hawker 850XP carrying the same number. We tell clients that before they book, because it is the most common source of after-the-fact surprise in this category.
Both types get into Boca Raton Airport and Witham Field at Stuart without difficulty, subject to the runway analysis we run for the actual weight and conditions on the day. For a Jupiter Island or Hobe Sound client that can mean a 15-minute drive to the aircraft instead of 45.
