As one of the most widely used airliners today, the Boeing 737 is a familiar sight at airports across the globe. But just how fast do those workhorse narrow-body jets cruise at in flight?

Here’s a quick answer: The maximum cruising speed of a Boeing 737 ranges from 485 to 587 mph depending on the model. While slight variations exist between generations, all 737s are designed for fuel efficiency at high subsonic speeds.

In this comprehensive guide, we’ll cover everything you need to know about how fast Boeing 737s travel. You’ll learn about speed capabilities of different 737 models, typical cruising speeds, factors that affect speed, and how the aircraft is engineered for optimum performance.

Maximum and Cruising Speeds of 737 Models

The Boeing 737 is one of the most popular and widely used commercial aircraft in the world. It is known for its reliability, efficiency, and versatility. When it comes to speed, the 737 is no slouch either. Let’s take a closer look at the maximum and cruising speeds of various 737 models.

Maximum Speed

The maximum speed of a Boeing 737 can vary depending on the specific model and variant. On average, the maximum speed of a 737 ranges from around 0.785 to 0.82 Mach, which is equivalent to approximately 586 to 614 miles per hour (mph) or 943 to 988 kilometers per hour (km/h).

This impressive speed allows the 737 to cover long distances in a relatively short amount of time.

It is worth noting that the maximum speed of an aircraft is typically not used during normal operations. It is mainly reserved for emergency situations or when the aircraft needs to reach its destination quickly due to unforeseen circumstances.

The 737’s maximum speed ensures that it can handle such situations with ease.

Cruising Speed

The cruising speed of a Boeing 737 is the speed at which it typically flies during normal operations. This speed allows the aircraft to maintain a balance between fuel efficiency and travel time. The cruising speed of a 737 can vary depending on factors such as altitude, weight, and weather conditions.

On average, the cruising speed of a 737 is around 0.78 Mach, which is equivalent to approximately 583 mph or 938 km/h. This speed ensures a smooth and comfortable journey for passengers while also optimizing fuel consumption for the airline.

It’s important to note that the cruising speed of a 737 can be adjusted by the pilots based on various factors. For example, in strong headwinds, the aircraft may fly at a slightly lower speed to conserve fuel, while in tailwind conditions, it may fly at a slightly higher speed to take advantage of the favorable wind.

Comparison with Other Aircraft

When comparing the speed of the Boeing 737 with other popular aircraft, it’s important to consider the specific models and variants being compared. However, as a general guideline, the 737’s maximum and cruising speeds are comparable to other narrow-body commercial aircraft such as the Airbus A320 series and the Bombardier CSeries.

It’s also worth mentioning that the Boeing 737 MAX, the latest iteration of the 737 family, boasts improved fuel efficiency and performance compared to its predecessors. This includes enhanced aerodynamics and more efficient engines, which contribute to a faster cruising speed and reduced fuel consumption.

Key Factors That Influence a 737’s Speed

When it comes to the speed of a Boeing 737, several key factors come into play. These factors determine how fast the aircraft can travel and are crucial in ensuring a safe and efficient flight. Let’s take a closer look at some of the main factors that influence a 737’s speed.

Aircraft Weight

One of the primary factors affecting the speed of a Boeing 737 is its weight. The heavier the aircraft, the longer it takes to accelerate and reach its intended speed. This is why airlines meticulously calculate the weight of passengers, cargo, and fuel before each flight.

By optimizing the weight distribution, pilots can ensure that the aircraft is operating at its most efficient speed.

Wind Conditions

Another important factor that affects the speed of a 737 is the wind conditions it encounters during flight. Headwinds, for example, can slow down the aircraft and require it to use more fuel to maintain the desired speed.

Tailwinds, on the other hand, can provide a boost and help the aircraft reach its destination faster. Pilots continuously monitor wind conditions and adjust their flight plans accordingly to optimize speed and fuel efficiency.


The altitude at which a 737 is flying also has a significant impact on its speed. As the aircraft climbs to higher altitudes, the air density decreases. This reduction in air density affects the performance of the engines and reduces the maximum speed the aircraft can achieve.

Pilots carefully select the optimal cruising altitude based on various factors, including weather conditions and air traffic, to ensure the aircraft can operate at its most efficient speed.

Engine Power

The power and performance of the engines installed on a Boeing 737 play a crucial role in determining its speed capabilities. The 737 is equipped with high-performance engines that provide the necessary thrust to propel the aircraft through the air.

These engines are specifically designed to deliver optimal performance while ensuring fuel efficiency. The power output of the engines, combined with the aircraft’s weight and other factors, ultimately determines its maximum speed.

Aerodynamic Design

The aerodynamic design of the Boeing 737 is another factor that contributes to its speed. The aircraft is designed with sleek lines and advanced wing technology to reduce drag and enhance its overall efficiency.

By minimizing air resistance, the 737 can achieve higher speeds while consuming less fuel. The aerodynamic design is continually improved through research and testing, ensuring that each new iteration of the 737 is faster and more efficient than its predecessors.
