How Fast Do Planes Fly? Speed Records, Takeoff Velocity & More
Ever wondered just how fast planes really go? Whether you're watching a jet soar overhead or buckling in for your own flight, the speed of airplanes can be both fascinating and surprising. From the moment they race down the runway to the time they cruise thousands of feet in the sky, planes operate at impressive speeds. In this guide, we’ll break down how fast planes fly during takeoff, cruising, and landing—and how different aircraft types compare when it comes to raw speed.

How fast do commercial planes fly?
Commercial airplanes are marvels of modern engineering, designed to carry hundreds of passengers safely and efficiently across vast distances. One of the most impressive aspects of these aircraft is their speed. But how fast do they really go?
What is a commercial plane?
A commercial airplane is a non-military aircraft used to carry passengers or cargo between airports. These are the planes most people fly on when traveling for work or vacation.
What affects how fast a plane flies?
Several factors influence an airplane’s speed. Here are three of the most important:
Altitude: Higher up, the air is thinner, which reduces resistance and lets planes fly faster.
Wind: Planes move quicker when flying with the wind (tailwind), and slower when flying against it (headwind).
Engine power (Thrust): The more powerful the engines, the faster a plane can go. Different planes have different engine capabilities.
How is airplane speed measured?
Airplane speed isn’t as simple as looking at a speedometer. There are several ways pilots measure it, all typically shown in knots (1 knot ≈ 1.15 mph):
Indicated airspeed (IAS): Shown on the plane’s dashboard, this is what the pilot sees in real time, based on onboard sensors.
True airspeed (TAS): This is the plane’s actual speed through the air, more accurate at higher altitudes.
Groundspeed (GS): How fast the plane is moving relative to the ground. This changes with wind conditions.
Calibrated airspeed (CAS): IAS adjusted for sensor errors—most important at lower speeds.
Mach: Used for very fast jets, this measures speed compared to the speed of sound (Mach 1). Since the speed of sound changes with altitude, so does the Mach number.
How fast do commercial planes go?
The speed at which airplanes fly is one of the most frequently asked questions among aviation enthusiasts and curious passengers. There are different speeds to take into consideration while focusing on commercial flights, and other factors such as aircraft type, cruise speed, takeoff and landing speed, and how wind and fuel consumption influence.
The takeoff speed of an aircraft varies according to the type of aircraft and the specific flight conditions. For example, a Boeing 737, one of the most common commercial airliners, achieves takeoff speeds of approximately 150 to 160 mph (240 to 280 km/h). During takeoff, the aircraft will deploy the flaps to increase lift and allow the aircraft to rise safely off the ground.
Landing speed, on the other hand, is lower than take-off speed and also depends on the type of aircraft and wind conditions. For the same Boeing 737, the landing speed is usually between 120 and 160 mph. Slowing down safely is crucial for a successful landing, and pilots use flaps and spoilers to help slow the aircraft down.
Cruising speed
Once a commercial aircraft reaches cruising altitude, it usually flies at a constant cruising speed to optimize fuel consumption and flight efficiency. The cruising speed of a Boeing 737, for example, is approximately 560 mph (840 km/h). This speed allows commercial flights to cover long distances efficiently and on time.
These speeds strike a balance between fuel efficiency, safety, and comfort. Planes usually fly at high altitudes—around 10,000 meters (33,000 feet)—where the air is thinner. This reduces drag (air resistance), allowing them to travel faster and more smoothly.
While these speeds aren’t breaking world records, they’re the result of decades of optimization by airlines and aircraft manufacturers to keep flights efficient, affordable, and on time.
Maximum speed
The maximum speed a commercial aircraft can reach is generally higher than its cruising speed. However, flying at higher speeds can significantly increase fuel consumption, so aircraft are usually operated at speeds optimized for the balance between speed and efficiency. The Airbus A320 can reach a maximum speed of close to 600 mph, although it is rarely operated at this speed on standard commercial flights.
Effect of wind
Wind plays a crucial role in the speed at which aircraft fly. A tailwind can make an airliner fly faster relative to the ground, while a headwind can reduce the relative speed. Pilots and airline navigation systems calculate speed taking into account the effect of wind to maintain safe and efficient flight.
Fuel consumption
Fuel consumption is closely related to the speed at which aircraft fly. Flying at an optimal cruising speed helps to minimize fuel consumption and CO2 emissions, which is crucial for sustainability and airline economics. Therefore, cruising speeds are designed to be as efficient as possible.
Maximum speeds of popular commercial planes
Here’s how fast some of the most common jets can fly at their top speed:
Airbus A380: 737 mph
Boeing 747: 614 mph
Boeing 737: 588 mph
These speeds are close to their maximum capability, but airlines usually cruise a bit slower to save fuel and reduce wear.
Other things that affect plane speed
Weather: Tailwinds help planes move faster over the ground, while headwinds slow them down.
Aircraft type: A large jet like the Boeing 777 performs differently than a small turboprop.
Altitude: Planes fly faster at higher altitudes because there’s less air resistance.
Why Don’t Planes Fly at Maximum Speed All the Time?
While planes can go faster, doing so burns a lot more fuel. Airlines prefer to cruise at speeds that balance time, efficiency, and cost. It’s all about getting you to your destination safely and sustainably.
How fast do airplanes fly? A complete guide to aircraft speed
When it comes to air travel, speed is a defining factor. But how fast do different types of aircraft actually go? From commercial jets and private planes to military marvels, here’s everything you need to know about airplane speeds—and what affects them.
How fast are commercial planes?
Commercial airliners, like those operated by Delta, British Airways, or Emirates, as we mentioned before typically cruise at speeds between 500 and 600 miles per hour (805–965 km/h). These speeds strike a balance between fuel efficiency, safety, and time savings, ensuring your flight is both economical for the airline and timely for you.
For example, the Boeing 747 cruises at around 560 mph, making it a benchmark for long-haul commercial travel.
Private jets vs. commercial aircraft
Private jets, though smaller, often fly faster than commercial planes—sometimes reaching speeds between 600 and 700 mph. Their lightweight design, powerful engines, and fewer passengers make them built for speed. A high-end jet like the Gulfstream G650 cruises around 610 mph, offering a faster, more flexible travel experience.
Military jets: The speed demons of the sky
Military aircraft are in a league of their own. Jets like the F-22 Raptor can soar past 1,500 mph, breaking the sound barrier with ease. These planes are designed for combat, agility, and extreme performance, often achieving speeds more than twice the speed of sound (Mach 2+).
The fastest ever? The SR-71 Blackbird, a reconnaissance jet, holds the record at over 2,100 mph (Mach 3.3).
Aircraft speed by type
Aircraft speed varies significantly by type, with smaller regional jets typically flying slower than long-haul wide-body aircraft. Here is a comparison about the average speed by aircraft type:
Commercial jets: 500–600 mph
Boeing 747: 570 mph
Private jets: 600–700 mph
Gulfstream G650: 610 mph
Propeller planes: Up to 300 mph
King Air 350: 312 mph
Helicopters: 150–250 mph
Airbus H160 – 200+ mph
Military jets: 1,200–2,100+ mph
SR-71 Blackbird – 2,100+ mph
Single-engine planes: 120–300 mph
Pilatus PC-12 NGX – 334 mph
Cargo planes: 500–600 mph
Boeing 747-400F – 590 mph
Breaking the sound barrier: How does it work?
The speed of sound at sea level is about 767 mph. When an aircraft exceeds this, it enters supersonic flight and creates a sonic boom—a shockwave heard from the ground. Only a few aircraft, like military jets or the retired Concorde, are built to achieve this.
How fast was the concorde?
The iconic Concorde could fly at over 1,350 mph (Mach 2.0), cutting the London–New York trip to under 3.5 hours. Though it was retired in 2003, it remains a symbol of supersonic passenger travel.
Aviation speed records
Fastest jet (Manned): SR-71 Blackbird – 2,100+ mph
Fastest aircraft ever: X-15 experimental plane – over 4,500 mph (Mach 6.7)
Fastest military interceptor: MiG-25 Foxbat – 2,190 mph
The future of speed in aviation
While commercial flights prioritize efficiency, safety, and cost, military and experimental aircraft continue to push speed boundaries. New technologies in aerodynamics, propulsion, and materials hint at a future with sustainable, faster travel—possibly reviving supersonic or hypersonic passenger jets.
