Southwest Airlines Boarding Groups

When it comes to air travel in the United States, Southwest Airlines stands out with its unique approach to boarding. Rather than assigning specific seats to passengers, Southwest has implemented an open seating policy that operates through an orderly system. This method relies on Southwest Airlines Boarding Groups, which are designed to make the boarding process faster, simpler, and less stressful for everyone involved. In this guide, we’ll break down how the boarding group system works, how you can improve your boarding position, and tips to make the most of it for a smooth and pleasant flying experience.

What Makes Southwest Different?

Most airlines assign each passenger a specific seat during booking or check-in. This can often result in delays as passengers search for their seats, rearrange luggage in overhead bins, or negotiate seat swaps. Southwest has taken a different path by allowing open seating. This means passengers choose their own seats once they board the aircraft. To maintain order and fairness in this system, the airline introduced boarding groups.

How Do the Boarding Groups Work?

Each Southwest boarding pass contains a group letter (A, B, or C) and a number (1–60). These are assigned based on your check-in time and whether you’ve purchased any upgrades or benefits. The boarding process follows this order:

1. Group A (1–60)
   
   
2. Group B (1–60)
   
   
3. Group C (1–60)
   
   

Boarding begins with A1 and continues numerically through C60. Gate agents call passengers in small batches (e.g., A1–A30), allowing them to line up in order. Once on board, passengers can select any open seat. Those with lower numbers have the first pick of seating options.

Factors That Affect Your Boarding Position

Several factors determine where you land in the boarding sequence:

1. Check-in Time

Check-in opens exactly 24 hours before the flight’s departure. Passengers who check in immediately often receive better boarding positions.

2. Early Bird Check-In

For a fee (usually $15–25 one way), passengers can purchase Early Bird Check-In. This automatically checks you in before the 24-hour window, improving your chances of landing in Group A or early B.

3. Upgraded Boarding

At the gate, if available, you can purchase Upgraded Boarding for a guaranteed spot in A1–A15. Prices vary based on demand and flight length.

4. Business Select Fares

These are the most expensive fare class on Southwest, and they include guaranteed A1–A15 boarding, a free premium drink, and other perks.

5. Southwest Rapid Rewards Status

A-List and A-List Preferred members (frequent flyers) receive priority boarding, often in Group A, regardless of check-in time.

6. Family Boarding

Families with children age six or younger are allowed to board between Groups A and B, if they weren’t already assigned to A.

7. Passengers Needing Assistance

Pre boarding is available for those who need extra time or assistance boarding the aircraft. They board before Group A.

Tips for Better Boarding Positions

• Set an Alarm for Check-In: If you’re not buying Early Bird, set an alarm to check in exactly 24 hours before your flight.
  
  
• Buy Early Bird When Needed: It can be a good value if you're on a full flight or traveling with others.
  
  
• Use Mobile Check-In: Download the Southwest app to check in and get your digital boarding pass quickly.
  
  
• Consider Business Select on Short Trips: If you need to be off the plane quickly, the A1–A15 spot can save valuable time.
  
  
• Book Flights Early: Boarding positions are partly influenced by how full the flight is. Booking early often gives you a better chance.
  
  

Choosing the Right Seat Once on Board

Because seats aren’t assigned, where you sit is entirely up to you—if you board early enough. Here's how to pick wisely:

• Front Rows: Great for quick exits and extra legroom, but may have limited under-seat storage.
  
  
• Exit Rows: These often offer more legroom but may come with restrictions (you must be able-bodied and 15+ years old).
  
  
• Window or Aisle: The earlier you board, the more options you'll have. Middle seats are usually the last to go.
  
  
• Over the Wing: These seats experience less turbulence, which some travelers prefer.
  
  
• Back of the Plane: Often the last to fill, good if you board late and want to avoid sitting in a middle seat.

Advantages of the Boarding Group System

Southwest’s boarding group system is designed to:

• Speed up the boarding process by minimizing bottlenecks.
  
  
• Allow flexibility for travelers to sit together without paying seat selection fees.
  
  
• Encourage early check-in and participation in loyalty programs.
  
  
• Simplify the flying experience for regular travelers.
  
  

Many passengers find it less stressful than traditional seating assignments, especially when they understand how to navigate the process.

Is the System Right for Everyone?

While many appreciate the flexibility, the system may not suit all travelers. Those who prefer a guaranteed seat next to a travel companion might find the open seating model less appealing—especially if boarding late. However, families and savvy travelers who plan ahead usually have a positive experience.
