Unpacking Southwest Airlines' Fleet: A Step-by-Step Guide to Passenger Capacity
Southwest Airlines is renowned for its single-aircraft type philosophy, exclusively operating Boeing 737s. This simplifies things considerably when trying to figure out passenger capacity, as you only need to consider the different variants of the 737 that Southwest flies.
How Many People Can Fit On A Southwest Airlines |
Step 1: Identify the Aircraft Model for Your Flight
How can you find out which Boeing 737 model your flight will be on? This is often the first and most crucial step. While Southwest primarily flies Boeing 737s, they operate several different versions, each with its own seating capacity.
-
Check your booking confirmation: Sometimes, the specific aircraft model is listed on your e-ticket or in your online reservation details.
-
Use flight tracking websites/apps: Websites like FlightAware or FlightStats often display the aircraft type for specific flights. Input your flight number, and you might find the information there.
-
Southwest's website or app: While not always prominently displayed, sometimes exploring the flight details on Southwest's own platforms can reveal the aircraft type.
-
Ask a Southwest representative: If all else fails, a quick call to Southwest customer service or asking a gate agent can provide you with the exact aircraft model.
Once you know the model, you can accurately determine the passenger capacity.
Step 2: Understand the Different Boeing 737 Variants and Their Capacities
Southwest Airlines currently operates three main variants of the Boeing 737 for passenger service. Each has a slightly different seating configuration and thus, a different maximum capacity.
Sub-heading: The Boeing 737-700
Tip: Read in a quiet space for focus.![]()
This has historically been the workhorse of Southwest's fleet.
-
Passenger Capacity: The Boeing 737-700 typically accommodates 143 passengers.
-
Seat Pitch and Width: Passengers can generally expect a seat pitch of around 31 inches and a seat width between 15.5 and 17.0 inches. While some earlier versions had 137 seats, Southwest reconfigured their 737-700 fleet to the 143-seat layout.
Sub-heading: The Boeing 737-800
A larger variant, the 737-800, allows Southwest to carry more passengers on busier routes.
-
Passenger Capacity: The Boeing 737-800 can seat up to 175 passengers.
-
Seat Pitch and Width: This model generally offers a slightly more generous seat pitch of 32 inches and a seat width of 17.8 inches, often with newer "Evolve" interiors designed for enhanced comfort.
Sub-heading: The Boeing 737 MAX 8
The newest addition to Southwest's fleet, the 737 MAX 8, is also designed for higher capacity and improved fuel efficiency.
-
Passenger Capacity: Similar to the 737-800, the Boeing 737 MAX 8 also accommodates 175 passengers.
-
Seat Pitch and Width: Passengers on the MAX 8 can expect a seat pitch of 32 inches and a seat width of 17.8 inches. These aircraft often feature Boeing Sky Interiors with larger overhead bins and mood lighting, contributing to a more spacious feel.
Step 3: Consider the "Open Seating" Policy and Its Implications
Southwest Airlines is unique among major U.S. carriers for its open seating policy. This means there are no assigned seats when you book your ticket. While it doesn't change the absolute number of people who can fit on the plane, it significantly impacts the boarding process and how passengers choose their seats.

Tip: Highlight sentences that answer your questions.![]()
-
Boarding Groups (A, B, C): Upon check-in (which opens 24 hours before your flight), you are assigned a boarding group (A, B, or C) and a number within that group (1-60+). The earlier you check in, generally the better your boarding position.
-
First-Come, First-Served: When your group is called, you line up at the gate according to your number and then board the aircraft. Once on board, you can choose any available seat.
-
Impact on "Fitting In": While the plane has a fixed number of seats, the open seating policy can sometimes lead to the perception of a flight being more or less full. For example, if a family wants to sit together, they might need to board earlier to secure a block of seats, even if the flight isn't completely full. Conversely, if you board late, you might find only middle seats remaining, even if the plane technically has empty spots.
Step 4: Rare Exceptions and Other Factors (Though Less Common with Southwest)
While Southwest primarily sticks to its standard configurations, a few other minor factors could theoretically affect "how many people can fit":
-
Infant in Arms: Infants under two years old can typically travel on an adult's lap without requiring their own seat, meaning the actual number of individuals on board can exceed the seat count by a small margin.
-
Operational Needs: In extremely rare circumstances, an aircraft might be temporarily reconfigured for specific operational reasons, but this is highly unlikely for scheduled passenger flights on Southwest.
-
Cargo/Weight Restrictions (Indirect Impact): While not directly related to passenger seating capacity, heavy cargo or specific flight conditions might lead to a reduction in the number of available seats if there are strict weight restrictions. However, for typical Southwest flights, this isn't a factor that impacts passenger count.
Summary of Southwest Airlines Passenger Capacities

-
Boeing 737-700: Up to 143 passengers
-
Boeing 737-800: Up to 175 passengers
