Ever wondered just how many people can squeeze into a Southwest Airlines plane? It's a common question, especially for those who appreciate the airline's unique open seating policy and frequent flights. The answer isn't a single number, as Southwest operates a fleet of different Boeing 737 models, each with its own passenger capacity. But don't worry, we're going to break it all down for you, step by step, so you'll be a Southwest seating expert in no time!
Ready to dive in and unravel the mystery of Southwest's passenger capacity? Let's get started!
Step 1: Understanding Southwest's Unique Fleet Strategy
First things first, it's important to know that Southwest Airlines has a very particular fleet strategy. Unlike many other airlines that operate a diverse range of aircraft from different manufacturers (like Airbus, Boeing, Embraer, etc.), Southwest is famously an all-Boeing 737 airline. This commitment to a single aircraft family simplifies their operations, from maintenance to pilot training.
Why is this important? It means that when we talk about how many people a Southwest plane can hold, we're always talking about a variant of the Boeing 737. This consistency is a cornerstone of their low-cost, high-efficiency model.
Step 2: Identifying the Current Workhorses of the Southwest Fleet
As of mid-2025, Southwest primarily operates three main types of Boeing 737 aircraft. These are the models you're most likely to encounter on your next Southwest flight.
Sub-heading: The Boeing 737-700
This is a stalwart of the Southwest fleet, having been a core part of their operations for many years.
Passenger Capacity: A Boeing 737-700 flown by Southwest typically holds 143 passengers.
Key Features: While it's one of the smaller variants in their current fleet, it's highly efficient for shorter to medium-haul routes.
Sub-heading: The Boeing 737-800
This is a stretched version of the 737, offering increased capacity.
Passenger Capacity: The Boeing 737-800 operated by Southwest can accommodate 175 passengers.
Key Features: You'll often find these on longer domestic flights or routes with higher demand due to their larger seating capacity.
Sub-heading: The Boeing 737 MAX 8
The newest generation of the 737 family in Southwest's active fleet, the MAX 8 incorporates advanced technology for improved fuel efficiency.
Passenger Capacity: Similar to the 737-800, the Boeing 737 MAX 8 also holds 175 passengers with Southwest's configuration.
Key Features: While it has the same passenger count as the 737-800, it offers better fuel efficiency and an extended range, making it a crucial part of Southwest's future fleet plans.
Step 3: Looking to the Future: The Boeing 737 MAX 7
Southwest has a significant number of Boeing 737 MAX 7 aircraft on order. These planes are expected to begin entering service in 2026 and are slated to replace the older 737-700s.
Anticipated Passenger Capacity: While the exact configuration can sometimes change, the Boeing 737 MAX 7 is expected to seat around 148 passengers for Southwest. This will be a slight increase from the 737-700 it replaces.
Significance: The introduction of the MAX 7 will further modernize Southwest's fleet, enhancing efficiency and potentially offering a slightly updated cabin experience.
Step 4: Putting it All Together – The Range of Southwest Capacities
So, to answer the overarching question, how many people can a Southwest Airlines plane hold?
Currently, a Southwest flight will typically carry either 143 passengers (on a 737-700) or 175 passengers (on a 737-800 or 737 MAX 8).
In the near future, with the introduction of the 737 MAX 7, you might also find planes seating around 148 passengers.
This focused approach to a single aircraft family, albeit with different variants, allows Southwest to maintain its operational simplicity while offering various capacities to suit different route demands.
Step 5: The Southwest Boarding Experience and Seating
It's crucial to remember that Southwest Airlines operates with an open seating policy. This means there are no assigned seats when you book your ticket. Instead, your boarding position (A, B, or C group, with a number) determines when you can enter the aircraft and choose your seat.
Sub-heading: How Boarding Order Impacts Your Seat Choice
"A" Group: If you're in the "A" group, you'll be among the first to board, giving you the widest selection of seats. This is where you'll find the best chance to sit with your travel companions, secure an aisle or window seat, or grab one of the few "Extra Legroom" seats (which Southwest is introducing in some retrofitted aircraft, typically the first five rows and exit rows).
"B" Group: The "B" group still offers a good selection, but prime spots might be taken.
"C" Group: Passengers in the "C" group will have the fewest options, often needing to take middle seats or whatever remains.
Sub-heading: Maximizing Your Seating Experience
Since seats aren't assigned, many Southwest passengers prioritize checking in exactly 24 hours before their flight to get the earliest possible boarding position. This is the key to getting the seat you want and ensuring you can sit with your group.
Pro Tip: If traveling with young children (six or younger), Southwest offers "Family Boarding" between the A and B groups, allowing up to two adults per child to board together to find seats.
Frequently Asked Questions about Southwest Airlines Capacity
Here are 10 common questions related to Southwest Airlines' passenger capacity, with quick answers:
How to find out the specific plane type for my Southwest flight? You can often see the aircraft type listed when you view your flight details on the Southwest Airlines website or app, usually under the "Flight Details" or "Aircraft Information" section.
How to guarantee I sit with my family on a Southwest flight? The best way is to check in exactly 24 hours before your flight to get early boarding positions. If traveling with a child six or younger, utilize Family Boarding. Otherwise, try to purchase EarlyBird Check-In or upgrade to a Business Select fare for a guaranteed A group boarding position.
How to know if my Southwest flight will be on a 737-700 or a 737-800/MAX 8? Check the aircraft type listed in your flight details. If it's not explicitly stated, you might look at the route popularity and length. Longer, higher-demand routes often utilize the larger 175-seat aircraft.
How to tell the difference between a 737-800 and a 737 MAX 8 once I'm on board? The 737 MAX 8 often features a more modern Boeing Sky Interior with sculpted sidewalls, larger window reveals, and dynamic LED lighting. However, both can have similar seat counts and general layouts.
How to find out about the new "Extra Legroom" seats on Southwest? Southwest is progressively introducing "Extra Legroom" seats in the first five rows and near exit rows on retrofitted 737-800 and MAX 8 aircraft. As of May 1, 2025, these are part of a phased update to their cabin layout. You can't reserve them beforehand but can choose them if available with an early boarding position.
How to deal with a full Southwest flight and limited seating options? If you have a late boarding position (especially in the C group), be prepared for middle seats. The flight attendants can sometimes help families or individuals find seats together if necessary, but it's not guaranteed.
How to know if Southwest will ever fly larger planes than the 737? Historically, Southwest has stuck to the Boeing 737 for operational simplicity. While they continuously evaluate their fleet needs, there are no current public plans to introduce significantly larger aircraft types outside the 737 family.
How to check the seat pitch on Southwest planes? The Boeing 737-700 typically has a seat pitch of 31 inches, while the 737-800 and 737 MAX 8 usually have a seat pitch of 32 inches.
How to understand Southwest's strategy of using only Boeing 737s? This strategy, known as a "single-type fleet," streamlines maintenance, reduces training costs for pilots and mechanics, simplifies spare parts inventory, and allows for greater flexibility in aircraft assignment.
How to find the total number of aircraft in Southwest's fleet? As of early to mid-2025, Southwest Airlines operates a fleet of over 800 Boeing 737 aircraft, making it the world's largest operator of the 737 family.
