Airbus Helicopters H135 vs Airbus Helicopters H155 vs Gulfstream G700

The Airbus Helicopters H135 is a light twin‑engine helicopter best suited to short‑range missions such as training, EMS, and urban transport. Its typical range is roughly 300–350 nautical miles depending on configuration and reserves, and it generally carries about 5–7 passengers (plus one or two pilots), with layouts varying by mission equipment. The Airbus Helicopters H155 is a larger, medium twin helicopter aimed at VIP and offshore roles. It offers a longer typical range than the H135, around 450–550 nautical miles, and a larger cabin that commonly accommodates about 8–12 passengers (again plus crew), making it more suitable for higher‑capacity point‑to‑point helicopter transport. The Gulfstream G700 is an ultra‑long‑range business jet in a different category entirely, designed for intercontinental travel. Its range is about 7,500 nautical miles, and while certified seating can be much higher, it is typically configured for roughly 12–19 passengers in high‑end corporate layouts.
