Southwest Airlines Boarding Groups are a key part of what makes the airline’s boarding process different from other carriers. Unlike traditional airlines that assign seats during booking, Southwest uses a first-come, first-served seating model. Your spot in line determines your seat — and that spot is based on your boarding group and number. For travelers unfamiliar with this process, it can seem confusing at first. But once you understand how it works and how to improve your boarding position, it becomes a straightforward system that many people prefer for its flexibility and speed.
Why Southwest Doesn’t Assign Seats
Southwest is known for doing things differently, and its seating policy is one of its most defining features. Rather than assigning seats ahead of time, the airline allows passengers to choose any open seat when they board the plane. This helps speed up boarding, reduces seat change requests, and gives travelers more freedom.
To manage the flow of passengers onto the plane, Southwest organizes everyone into boarding groups, which determine when you get on the aircraft.
The Basics of the Boarding Process
Each passenger is assigned a boarding group A, B, or C along with a number between 1 and 60. This combination, such as “B12” or “A45,” is printed on your boarding pass. Boarding begins with A1 and proceeds in order up to C60.
Here's the typical order of boarding:
Preboarding: For passengers needing special assistance or accommodations.
Group A (1–60): Highest boarding priority for most travelers.
Family Boarding: Parents with children aged 6 or under can board after Group A.
Group B (1–60)
Group C (1–60): Generally boards last, so seat choices may be limited.
Since there are no assigned seats, earlier boarding means more options for where you sit — whether that’s a window, aisle, or a spot near the front.
How Is Your Boarding Position Determined?
Several factors influence which group and number you receive:
1. Time of Check-In
Passengers who check in exactly 24 hours before their flight usually receive better boarding numbers. This is the most common method of securing a decent position.
2. EarlyBird Check-In
For an additional fee (usually $15–25 per one-way trip), Southwest offers EarlyBird Check-In, which automatically checks you in 36 hours before departure. While it doesn’t guarantee a specific spot, it generally places you ahead of those who check in manually.
3. Business Select Fares
These premium tickets come with automatic priority boarding positions between A1 and A15. Business Select travelers also receive extra Rapid Rewards points and a complimentary premium drink.
4. A-List & A-List Preferred
Southwest’s frequent flyer program includes elite tiers. Members with A-List or A-List Preferred status are automatically assigned earlier boarding positions as a perk of their loyalty.
5. Upgraded Boarding at the Gate
If available, passengers can purchase an upgrade at the gate for a guaranteed A1–A15 position. This is useful for those who need to sit near the front or want early access to overhead bin space.
6. Family Boarding
Families traveling with small children (age six or under) can board between Groups A and B if they weren’t already assigned an earlier group.
Tips to Improve Your Boarding Spot
If you want a good seat especially if you're traveling with others it helps to know how to work the system:
Set a reminder to check in the moment the 24-hour window opens.
Buy EarlyBird Check-In if you’re concerned you might forget or want to avoid the rush.
Travel light if you’re boarding late — overhead bin space fills quickly.
Book Business Select if early boarding is a priority and you value extra perks.

Choosing the Right Seat Onboard
Because it’s open seating, your boarding position plays a huge role in the kind of seat you’ll get. Here are common preferences:
Front of the plane: Ideal for quick deplaning or short layovers.
Exit row: Offers extra legroom but is only available to passengers 15+ and capable of assisting in an emergency.
Window or aisle: These go fast, so aim for Group A or early B to snag one.
Back rows: Less popular, but often more open if you're boarding in Group C.
If you're traveling with someone and want to sit together, early boarding is key — otherwise, you may need to ask other passengers to switch (which they aren’t required to do).
Is This Boarding Style Right for Everyone?
Southwest’s approach is a breath of fresh air for some and a headache for others. It favors travelers who are organized and don’t mind a little unpredictability. On the plus side, you won’t pay extra just to choose a seat in advance. On the downside, it requires some effort — especially if you want to sit with others or near the front.
If you value flexibility, minimal fees, and don’t mind setting an alarm to check in, the system works well. If you prefer the peace of mind that comes with assigned seating, other airlines may be a better fit for your style.
Final Thoughts
Southwest’s boarding process is simple once you understand how it works. While it’s different from traditional airlines, many passengers find it easy to navigate — especially with a little planning. Whether you check in early, purchase EarlyBird, or invest in a Business Select fare, improving your boarding position can make a big difference in your overall flight experience.
By learning how the system operates, you can board with confidence, choose your seat with ease, and enjoy a smooth start to your journey.
