Have you ever looked out the window of a Southwest Airlines flight and wondered, "Just how fast are we actually going up here?" It's a question many travelers ponder, mesmerized by the clouds rushing by. While it might feel like you're simply floating, Southwest Airlines planes are actually traversing the skies at impressive speeds, all while prioritizing safety and efficiency. Let's delve into the fascinating world of commercial aviation speeds, specifically focusing on Southwest Airlines.
Step 1: Let's Demystify Airspeed - It's More Than Just a Number!
Before we talk about specific speeds, it's crucial to understand that an airplane's speed isn't a single, fixed number. It varies significantly depending on the phase of flight and a variety of external factors. So, put on your metaphorical pilot's cap, and let's explore!
-
Cruising Speed: This is the speed at which the aircraft travels for the majority of the flight, once it has reached its optimal altitude. It's the most consistent and efficient speed for long-distance travel.
-
Takeoff Speed: The speed required for the aircraft to lift off the ground.
-
Landing Speed: The speed at which the aircraft touches down on the runway.
-
Taxi Speed: The speed at which the aircraft moves on the ground at the airport. You'd be surprised how slow it is!

Step 2: Understanding Southwest's Fleet: The All-Boeing 737 Strategy
One of the key factors influencing Southwest's flight speeds is its entirely Boeing 737 fleet. This unique strategy contributes to their operational efficiency. They operate several variants of the Boeing 737, including:
-
Boeing 737-700: A staple of their fleet for many years, offering a good balance of range and capacity.
-
Boeing 737-800: A slightly larger variant, providing more seating capacity.
-
Boeing 737 MAX 8: The newest generation of the 737, designed for improved fuel efficiency and range. Southwest is also awaiting delivery of the 737 MAX 7.
Because all their pilots are trained on the same aircraft type, and maintenance procedures are streamlined, it allows for a highly efficient operation.
Step 3: The Nitty-Gritty: How Fast Do Southwest Planes Really Fly?
Now for the answer you've been waiting for!
Cruising Speeds: Soaring Through the Skies
QuickTip: Keep going — the next point may connect.
When a Southwest Airlines Boeing 737 reaches its cruising altitude, typically between 30,000 and 40,000 feet, it generally flies at speeds ranging from:
-
Approximately 500 to 575 miles per hour (805 to 925 kilometers per hour).
-
This can also be expressed in Mach numbers, which is the ratio of the aircraft's speed to the speed of sound. For a Boeing 737, the cruising speed is typically around Mach 0.74 to Mach 0.79.
It's important to note that actual cruising speed can vary slightly based on factors like wind conditions (tailwind vs. headwind), air traffic control instructions, and the specific route. Pilots often adjust speed to optimize for fuel efficiency and on-time performance.
Takeoff and Landing Speeds: The Critical Phases
While cruising speed is where the plane spends most of its time, takeoff and landing speeds are equally crucial for safety.
-
Takeoff Speed: For a Boeing 737, takeoff speeds typically fall in the range of 150 to 180 miles per hour (240 to 290 km/h). This speed ensures sufficient lift for the aircraft to become airborne.
-
Landing Speed: Landing speeds are generally lower than takeoff speeds, ranging from around 130 to 160 miles per hour (210 to 260 km/h). This slower speed allows for a controlled and safe touchdown.
Taxi Speeds: The Ground Crawl
You might find it amusing how slowly planes move on the ground compared to their airborne speeds. This is for critical safety reasons.
-
Southwest Airlines, like other major carriers, adheres to strict taxi speed limits. Pilots typically taxi their Boeing 737s at speeds between 20 to 30 knots, which translates to roughly 23 to 35 miles per hour (37 to 56 km/h).
-
In adverse weather conditions or when making tight turns, pilots will reduce their taxi speed even further, sometimes down to 10 knots (around 11.5 mph or 18.5 km/h). It's a deliberate and precise operation.
Step 4: Factors Influencing Flight Speed
While we've given you a range of speeds, several factors can influence how fast a Southwest Airlines plane flies on any given journey.
-
Wind Conditions: A strong tailwind can significantly increase the aircraft's ground speed (the speed relative to the ground), while a headwind will decrease it, requiring the aircraft to fly faster through the air to maintain its schedule.
-
Air Traffic Control (ATC) Directives: ATC manages the flow of aircraft in the sky. They may instruct pilots to speed up or slow down to maintain safe separation from other planes or to optimize traffic flow.
-
Flight Route and Distance: Shorter flights might involve less time at optimal cruising altitude, while longer flights will spend more time at those higher, faster speeds.
-
Aircraft Weight: The total weight of the aircraft (passengers, cargo, fuel) can impact its optimal cruising speed and fuel efficiency.
-
Turbulence: Pilots will adjust speed and altitude to avoid or minimize the impact of turbulence, prioritizing passenger comfort and safety.
-
Fuel Efficiency: Airlines are constantly looking for ways to optimize fuel consumption, and this often involves flying at a speed that balances speed with efficiency.

Step 5: Southwest's Efficiency and Speed Philosophy
Southwest Airlines is renowned for its operational efficiency and quick turnarounds. While their planes fly at similar speeds to other airlines operating the same aircraft types, their overall operational model is designed for speed on the ground and in the air. Their point-to-point routing, single aircraft type, and efficient boarding procedures contribute to their ability to complete more flights per day with their fleet.
Their famous "10-minute turnarounds" of the past might be a legend now due to increased regulations and passenger numbers, but the spirit of efficiency remains integral to their operations.
10 Related FAQ Questions
How to calculate an airplane's ground speed?
You can often track an airplane's ground speed using flight tracking websites and apps (like FlightAware or Flightradar24) which provide real-time data.
How to understand the difference between airspeed and ground speed?
Airspeed is the speed of the aircraft relative to the air it's flying through, while ground speed is the speed of the aircraft relative to the ground. Wind conditions cause these two to differ.
QuickTip: Reread for hidden meaning.
How to know a plane's typical cruising altitude?
Commercial airliners, including Southwest's Boeing 737s, typically cruise at altitudes between 30,000 and 40,000 feet (approximately 9,100 to 12,200 meters).
How to measure aircraft speed?
Aircraft speed is measured using instruments like pitot tubes, which determine airspeed, and GPS systems, which determine ground speed.
How to determine the maximum speed of a Boeing 737?
While the cruising speed is around Mach 0.74-0.79, the maximum operating speed (or "redline" speed) of a Boeing 737 is higher, around Mach 0.82, but it is rarely flown at this speed during commercial operations due to fuel efficiency and safety considerations.
How to find out the speed of my specific Southwest flight?
You can use flight tracking websites or apps by entering your flight number. These platforms often display the current speed (ground speed) of the aircraft.
QuickTip: Scan the start and end of paragraphs.
How to account for headwinds and tailwinds when flying?
