Private jets generally offer a smoother ride than commercial airliners, primarily because of their ability to fly at higher altitudes. Most commercial jets cruise between 31,000 and 38,000 feet, where they share "congested" air corridors and are subject to weather patterns. Private jets, however, can often climb to 41,000 to 51,000 feet. At these heights, the air is thinner and significantly less turbulent, as they are flying well above the majority of weather systems and the "choppy" air found in lower altitudes. Furthermore, private jets have a higher wing loading—meaning they are heavier relative to their wing area—which helps them "cut through" turbulence rather than being tossed by it. Additionally, private pilots have more flexibility to change altitude or deviate from a flight path immediately to avoid known areas of turbulence, whereas commercial pilots are often restricted by strict ATC routing and the needs of other aircraft. While no plane is immune to the laws of physics, the combination of altitude and agility makes private travel a much calmer experience.
