Southwest Airlines does not assign seats — instead, you choose any available seat after boarding in your assigned group. Your boarding group (A, B, or C) determines your seat choice, and your position within that group (1–60) determines how early you board. Understanding the system lets you reliably get an A group and the seat you want.
How Southwest Boarding Groups Are Assigned
| Boarding Order | Who Gets This Position |
|---|---|
| A1–A15 | Business Select fare passengers; upgraded boarding purchasers; A-List Preferred members |
| A16–A60 | A-List status members; early EarlyBird Check-In purchasers; 24-hour check-in window leaders |
| B1–B60 | Later EarlyBird purchasers; mid-to-late 24-hour check-ins on less busy flights |
| C1–C60 | Passengers who checked in late or did not purchase EarlyBird |
| Family boarding | After A group, before B group — families with children 6 and under |
| Preboarding | Passengers needing assistance; active military in uniform; passengers with disabilities |
The Four Ways to Get Group A
1. Buy Business Select Fare
Business Select includes A1–A15 boarding — the first 15 positions — guaranteed. It also includes one drink coupon, priority security access at some airports, Fly By lanes, and bonus points. Best for: Travelers who need a specific seat (window, exit row) or cannot afford to middle-seat on a 5-hour flight.
2. Earn A-List Status
A-List is Southwest’s mid-tier status:
- Earn: 25 one-way qualifying flights or 35,000 tier qualifying points (TQPs) per calendar year
- Benefit: Priority A-group boarding (not A1–A15 specifically, but A position before other passengers)
- Also: 25% more Rapid Rewards points, same-day changes free, priority phone and check-in lanes
A-List Preferred (50 qualifying flights or 70,000 TQPs):
- All A-List benefits
- 100% more Rapid Rewards points per flight
- Complimentary inflight Wi-Fi (high value on Southwest’s Starlink-equipped fleet)
- Unlimited same-day standby
3. Purchase EarlyBird Check-In
EarlyBird ($15–$25 per person per segment) automatically checks you in 36 hours before departure. Regular passengers must check in at the 24-hour mark manually; EarlyBird checks you in 12 hours earlier.
Is it worth it?
| Flight Duration | EarlyBird Worth It? | Why |
|---|---|---|
| 1–2 hours | Sometimes | Middle seat tolerable; save the $15 on short trips |
| 3–5 hours | Usually yes | Middle seat on a 5-hour flight = real discomfort |
| Red-eye | Usually yes | Window or aisle matters more for sleep |
| Busy holiday routes | Yes | Competition for A group is highest; EarlyBird protects your position |
4. Check In Exactly at 24 Hours
If you decline EarlyBird, set a phone alarm for the exact 24-hour mark before your departure and check in at the second. On less busy flights, checking in promptly at 24 hours can still produce a B1–B10 position with reasonable seat choice. On peak dates, you may land in B30+ without EarlyBird.
Upgraded Boarding — Day-of Improvement
If available, Southwest sells Upgraded Boarding at the gate or on the app after check-in. This purchases an A1–A15 position for $30–$50 per segment. It is only available if a Business Select passenger does not show, leaving a gap in A1–A15.
When to use it: When you arrive at the gate and the upgrade is available, and you are currently in B or C group and want a specific seat for a longer flight.
Family Boarding Policy
Families with children 6 years old or younger board between Group A and Group B regardless of their checked-in boarding position. A family with EarlyBird in the A group would board even earlier, but a family with a C group position can still use family boarding.
One or two accompanying adults may board with the children. Other family members (relatives without young children) must board in their own position.
What Happens If You Get Group C?
Group C typically boards 20–30 minutes after Group A. By the time Group C boards on a full flight:
- Window seats in the first 15 rows are almost certainly gone
- Aisle seats are limited
- Middle seats throughout the cabin are available
- Exit row seats may be gone (they go fast)
Strategy in Group C: Head toward the back of the plane — rear middle seats are the last to fill and fellow passengers tend to prefer sitting toward the front. Some passengers also find overhead bin space in the rear easier to access.
Rapid Rewards Points and Boarding
Rapid Rewards (Southwest’s loyalty program) points do not directly affect boarding position. However:
- Rapid Rewards credit cards (Chase Southwest) earn TQPs that count toward A-List status
- The Southwest Priority Card ($149/year) includes 4 upgraded boardings per year and 7,500 bonus points at anniversary
- The Southwest Performance Business Card includes 4 upgraded boardings per year and EarlyBird credits
Key Takeaways
- Southwest’s boarding groups A, B, and C determine seat choice — A boards first with the most options; C boards last with the fewest
- Business Select fare guarantees A1–A15; EarlyBird Check-In ($15–$25/segment) gives a 36-hour head start on check-in for better A/B position
- A-List status (25 qualifying one-way flights/year) provides A-group boarding on every flight
- Upgraded Boarding (available day-of at the gate for $30–$50) can move you to A1–A15 if Business Select seats are unclaimed
- On longer or high-demand flights, EarlyBird or Business Select is worth the cost to avoid a middle seat for 4+ hours
