The Real Reason Private Jets Fly Above Commercial Traffic

Private jets can often cruise above the main stream of commercial air traffic because higher altitudes can open up less congested airspace, thinner air, and more favorable operating conditions. The benefit isn’t universal, but the top end of business aviation is built to reach significantly higher levels than most scheduled aircraft. Typical commercial cruise altitudes run about 30,000 to 42,000 feet, with many flights near the mid-30,000s. Private jets commonly operate around 41,000 to 45,000 feet, while aircraft such as the Gulfstream G650 have a published service ceiling of 51,000 feet. Route, weight, weather and air-traffic control all determine the optimal level.
