The Ultimate Guide to Flight Durations & Aviation Speeds
Ever wondered why your flight takes so long, or why flying from New York to London is faster than the return trip? Let's break down the science of flight times, the Jet Stream, and aircraft speeds.
1. How fast do commercial planes actually fly?
The average cruising speed of a standard commercial passenger jet (like a Boeing 737 or Airbus A320) is approximately 500 to 550 mph (800 to 885 km/h). They typically cruise at an altitude of 30,000 to 40,000 feet, where the air is thinner, reducing drag and increasing fuel efficiency.
However, smaller regional planes, known as turboprops, fly much lower and slower, averaging around 300 to 400 mph (480 to 640 km/h). Conversely, private jets like the Gulfstream G650 can cruise at near supersonic speeds (Mach 0.90), making them significantly faster than commercial airlines.
2. The Jet Stream: Why Eastbound flights are faster
If you've ever flown across the Atlantic or across the United States, you may have noticed that flying West to East is significantly faster than the return trip. This is due to the Jet Stream.
Jet streams are fast-flowing, narrow air currents found in the atmosphere. Because the Earth rotates from West to East, these winds blow in the same direction. An eastbound flight (e.g., Los Angeles to New York) catches a tailwind, which physically pushes the plane, boosting its ground speed up to 100 mph faster. The return flight battles a headwind, significantly slowing it down.
3. Block Time vs. Flight Time
When you look at your ticket, the duration listed is the Block Time, not the Flight Time.
- Flight Time (Air Time): The exact amount of time the wheels are off the ground.
- Block Time: The total time from when the plane pushes back from the departure gate to when it arrives at the destination gate.
Our calculator automatically adds roughly 45 minutes to your estimated cruise time to account for taxiing, the runway queue, takeoff, and landing, giving you an accurate estimate of your true Block Time.
