Southwest Airlines Boarding Groups are central to the airline’s unique and well-known open seating policy. Unlike most airlines that assign specific seats when you book or check in, Southwest allows passengers to choose any available seat once they board. This system, while simple in theory, depends on a structured boarding process that determines who boards when — and therefore who gets first pick of seats. For first-time flyers or even regular travelers who haven’t flown Southwest recently, understanding how this process works can make your trip a lot smoother and help you secure the seat you want without extra stress.
What Makes Southwest’s Boarding Process Different?
At most airlines, seat assignments are either selected during booking or automatically assigned later. You know where you’ll sit before stepping onto the plane. Southwest does things differently by offering open seating, meaning passengers choose their seats as they board.
This creates flexibility and, when executed well, can even speed up the boarding process. But it also places importance on your boarding position — the earlier you board, the more seats you have to choose from. To keep it organized, passengers are placed into boarding groups and assigned a number that dictates the order they’ll board.
What Determines Your Boarding Group?
Several factors influence your boarding position:
- Check-In Time
The most common way to secure an earlier boarding group is to check in exactly 24 hours before your scheduled departure. Those who check in early typically receive better boarding numbers.
- EarlyBird Check-In
For a fee (usually $15–25 one-way), you can purchase EarlyBird Check-In. This automatically checks you in 36 hours before your flight, which usually results in a better boarding position than manual check-in at the 24-hour mark.
- Business Select Fare
If you purchase a Business Select ticket (Southwest’s highest fare class), you’re guaranteed a boarding position between A1 and A15. This is ideal for business travelers or anyone wanting to board first.
- A-List & A-List Preferred Status
Frequent flyers who qualify for A-List or A-List Preferred status through the Rapid Rewards loyalty program get priority boarding. This benefit typically lands them in Group A automatically.
- Upgraded Boarding
If available, Southwest sells Upgraded Boarding positions (A1–A15) at the gate on the day of travel. Prices vary depending on demand and the flight.
- Family Boarding
Families with children aged six or younger are allowed to board after Group A and before Group B, even if they weren’t assigned early groups. This helps families sit together without paying for upgrades.
- Preboarding
Passengers with disabilities or those needing extra time can request preboarding. These travelers board before Group A.
Tips for Getting a Better Boarding Position
If you’re hoping to sit in a preferred area — such as near the front of the plane, at a window or aisle, or in the exit row — getting a good boarding position is essential. Here’s how to improve your odds:
Set a timer for exactly 24 hours before your flight to check in immediately.
Consider EarlyBird Check-In if you’re flying on a full flight or during peak travel times.
Look into Business Select or Upgraded Boarding if getting on early is important for your schedule or comfort.
Download the Southwest app for fast and easy mobile check-in and digital boarding passes.
Book flights early — the earlier you buy, the more options you’ll have for choosing services like EarlyBird or Business Select.
Choosing the Right Seat Once You’re on Board
Once on the plane, it’s first come, first served for seating. Here’s a breakdown of seat types to help you plan:
Front Rows: Great for quick exits after landing but may have limited under-seat storage.
Exit Rows: These often have extra legroom but are restricted to passengers aged 15 and older who are able to assist in an emergency.
Over the Wing: These seats experience less turbulence and noise, making them a comfortable choice for many.
Aisle vs. Window: Popular seats for comfort or scenery — the earlier you board, the more likely you’ll find one open.
If you're traveling in a group, try to check in early together or purchase upgrades to ensure you're able to sit near each other.
Final Thoughts: Is It Worth It?
Southwest’s boarding system may seem a little unusual at first, especially if you’re used to knowing your seat in advance. But once you understand how it works, it can actually be less stressful than traditional assigned seating. There's no last-minute scramble to swap seats or pay for specific seat assignments — just board in your group and pick what’s open. Whether you're a solo traveler, flying with family, or just looking to make your flight experience smoother, learning the ins and outs of Southwest’s boarding system is key. A little planning can go a long way in securing the seat you want and starting your trip off right.
