Midsize jets are where Houston charter starts covering the country: transcontinental legs, a stand-up cabin, and real baggage capacity. The Gulfstream G100 / G150 / IAI Astra SPX is a practical fit for a small Houston team traveling together.
Gulfstream Aerospace / Israel Aerospace Industries introduced the Gulfstream G100 / G150 / IAI Astra SPX in 2006. The lavatory is belted rather than fully enclosed, which is worth knowing before booking a long leg on it. Astra SPX predecessor produced 1996-2001.

Why the Gulfstream G100 / G150 / IAI Astra SPX Fits Houston
It carries a working group out of Houston to either coast with baggage, which is the practical dividing line between midsize and light.
The published 2,950 nautical miles covers Las Vegas, Los Angeles, and New York nonstop out of Houston once you allow for winds and reserves. Real-world range moves with payload, temperature, and winds, so the operator checks it against your specific trip.
