Commercial aviation has changed global travel, making it possible to cross entire continents in a fraction of the time it once took. From the early days of the Wright brothers, airplanes have become faster, and more efficient. They’re also safer than ever and have earned their title as the safest mode of transportation. It was in the early 1900s when we finally leaped to commercial air travel, with one of the first known commercial planes being the Boeing 247 in 1933, before other planes like the Douglas DC-8 joined the industry in the 1950s, going on to the release of the much more sophisticated Boeing 737.

While frequent flyers may take them for granted, many wonder how these impressive machines travel, especially at high speeds. Have you ever wondered how fast these commercial planes fly? And what about their top speeds? On average, commercial planes cruise 460 to 575 miles per hour, which allows them to cover vast distances. Factors like altitude, flight phase, wind, and load can affect the speed of a commercial plane.

A commercial plane is a specialized airplane to transport passengers and cargo along scheduled routes. These planes are operated by airlines, charter companies, and corporations. These planes serve as the backbone of global travel and freight . Commercial planes vary widely in size and purpose. Smaller regional planes are capable of short-haul flights, while larger wide-body jets like the Airbus 380 or legendary Boeing 747 are designed for long-haul intercontinental journeys.

Despite the differences in design and structure, each type of commercial aircraft is engineered to be fuel-efficient and fast, maximizing their capabilities while saving the fleet owners money. Unlike cargo planes, commercial passenger planes come with interiors designed to keep passengers comfortable during long hours in the sky. They feature amenities such as pressurized cabins, in-flight entertainment systems, and ergonomic seating. Manufacturers are constantly working to increase the efficiency of jet engines, and that is having a huge impact on the performance and speed of these planes.

Commercial planes can reach incredible speeds, but can vary greatly even during a single flight. During takeoff, speeds typically range from 140 to 156 knots (160 to 180 mph) as the plane gains the lift needed to leave the ground. Once airborne, planes accelerate to climb speed. The final cruising altitude plays a huge role as aircraft cruise at different altitudes. The initial climb speed of a 737-800 is 165 knots (about 190 mph) to 5,000 ft. The 737 then accelerates steadily until it reaches its cruising speed of 514 mph.

That speed is maintained throughout most of the flight. For long-distance flights, the cruising speed is typically around 80-90% of a plane’s maximum speed. This throttle level saves fuel in these flights. Notably, long-distance jets like the Boeing 787 Dreamliner can reach cruising speeds of 488 knots (562 mph).

As a flight approaches its destination, the plane decelerates to its approach or landing speeds. These lower speeds prepare pilots for a smooth landing. Landing speeds also depend on the aircraft’s weight and other factors. For instance, the Airbus A320’s landing speed typically ranges between 220 and 250 knots (roughly 250-290 mph), while a Boeing 737’s landing speed ranges from 137 to 162 knots (about 158-186 mph).

The maximum capabilities of commercial planes often spark the interest of aviation enthusiasts. While most planes cruise at 460 to 575 miles per hour, their top speeds exceed this range. Four-engine planes are designed to travel longer distances at high speeds. For instance, the Boeing 747-400 has a maximum speed of 656 mph. The Airbus A380, known for its capacity of up to 853 passengers, can reach a top speed of 634 mph.

Two-engine planes dominate modern commercial aviation because they’re efficient and powerful. While they’re generally slower than four-engine models, they are still capable of reaching high speeds. Modern twin-engine aircraft like the Boeing 787 Dreamliner and Airbus A350 have impressive top speeds of 690 mph and 683 mph, respectively. Among twin-engine aircraft, the Airbus A330 neo stands out with its maximum speed of 571 mph, and the Boeing 787-8 Dreamliner cruises at 561 mph.

Three-engine jets are rare these days, and they have a smaller role in commercial aviation, even though they were once a popular choice. During their prime, they were a middle ground between the twin-engine and the four-engine planes. They were pretty fast too. The McDonnell Douglas MD-11, for instance, had a cruising speed of 587 mph, while the Lockheed L-1011 TriStar cruised at just over 600 mph. On the other hand, turboprop planes use turbine engines that drive propellers, which makes them efficient. Even though they are slower, they play a huge role in regional flights. The Saab 340 has a maximum speed of 283 knots (about 326 mph).

Even if they’re capable of these speeds, commercial planes generally avoid flying faster than Mach 1 (the speed of sound) for a few reasons. For starters, when an aircraft approaches or exceeds the speed of sound, shockwaves form around it. These waves can create turbulence and make the plane difficult to control. Also, supersonic planes burn considerably more fuel compared to subsonic aircraft, which makes them more expensive to operate. These planes also come with high manufacturing and operating costs.

In the past, supersonic jets like the Concorde broke records by pushing boundaries even further and could reach a top speed of Mach 2.04 (approximately 1,354 mph). However, these supersonic speeds came with high fuel consumption and noise. This limited its mainstream potential, and the Concorde made its last flight in 2003. Boom is working on a supersonic jet called the Overture, and hopes to put it in the sky by 2029 with a top speed of 1,122 mph.

The speed of an aircraft is influenced by several mechanical and environmental factors. Engine thrust is a primary driver of speed, as it generates the forward propulsion required for flight. Another important factor is the aircraft’s weight or load, which includes passengers, cargo, and fuel. The weight-to-thrust ratio greatly impacts acceleration and climb rates. Heavier planes experience drag, which is why they often have slower take-off speeds. Lighter planes, however, can achieve higher speeds with the same thrust.

At higher altitudes, the air becomes thinner, which reduces drag and allows for efficient cruising speeds. This is why commercial planes fly at altitudes between 31,000 and 42,000 feet as this is the range where they can maintain high speeds without consuming too much fuel. Another key consideration in airspeed is the weather, particularly winds. While tailwinds boost ground speed — which enables faster speeds — headwinds slow the aircraft and lead to increased flight times. Temperature is another environmental factor that affects speed. Warmer air temperatures reduce air density. This can decrease climb performance. On the other hand, cooler air improves engine efficiency and allows for faster climb speeds.
