Commercial airliners fly at a cruising altitude of approximately 30,000 – 40,000 feet (9,144 – 13,000m). Business jets fly at approximately 40,000 – 50,000 feet (12,192 – 15,240m) during high-altitude flight. Of course, altitudes may vary depending on traveling distance and weather conditions.
Business jets cruise at approximately the same speed as large airliners. Although performance varies by class, some are even capable of flying even faster than commercial airliners.
