Southwest doesn't sell assigned seats the way other airlines do — instead, your boarding position decides which seats are still open when you step on the plane. That's where Southwest EarlyBird seat upgrade options come in: they help you board earlier and claim a better seat. Here's how each option works and which is worth paying for.
Not sure which boarding add-on is best for your trip? Call +1 (855) 302-0422 (24/7) and our agents will set up the right one for you.

How Southwest boarding works
Southwest uses open seating. You're assigned a boarding group (A, B, or C) and a number; lower numbers board first and get the best pick of open seats. The earlier you board, the more likely you'll get an aisle, a window, or a seat near the front. Your options to board earlier:
- EarlyBird Check-In — automatically checks you in early for a better boarding position (a paid add-on).
- Upgraded Boarding — when available, buy a spot in the coveted A1–A15 group near the gate.
- Business Select fare — includes a premium early boarding position.
- Check in exactly 24 hours before — free, but you'll be racing everyone else.
EarlyBird vs Upgraded Boarding vs free check-in
| Option | Typical cost | What you get |
|---|---|---|
| Free 24-hour check-in | Free | Position depends on how fast you check in |
| EarlyBird Check-In | Per-segment fee | Automatic early boarding position |
| Upgraded Boarding | Higher fee (if available) | A1–A15, near the front of the line |
| Business Select | Premium fare | Top boarding + extras |
Prices vary by route and demand and change often — call to confirm yours.
Which option should you pick?
- Want a good seat with zero hassle? EarlyBird is the easy choice.
- Want the very front and to deplane first? Upgraded Boarding (A1–A15).
- On a budget? Set a reminder and check in exactly 24 hours before — it's free.
- Traveling with family? Earlier boarding helps you sit together.
Boarding and flight changes
If you change your flight, your boarding position can reset — but since Southwest has no change fee, you stay flexible. See the Southwest flight change with no fee guide. Note that EarlyBird purchases may not always carry over to a new itinerary, so check before you switch.
Pair it with the right fare and timing
Boarding perks matter most on full flights. If you're booking soon, our Southwest last-minute flight deals guide helps you grab a fare, and travelers in a group should read Southwest group booking help. Timing your purchase well can also save on the base fare — see the best time to book a flight for the cheapest fare.
Is EarlyBird actually worth it?
EarlyBird pays off most in specific situations. Consider buying it when:
- You're on a full or popular flight where good seats vanish fast.
- You want a specific seat type — a window to sleep or an aisle to stretch.
- You're traveling with family and need seats together.
- You can't reliably check in exactly 24 hours before departure.
- You have a tight connection and want to sit near the front.
It's less essential on quiet, half-empty flights, or if you're happy with whatever seat you get. When you're unsure, we'll look at how full your flight is and tell you whether it's worth the add-on.
Free ways to improve your boarding position
Don't want to pay? You can still boost your spot in line:
- Set a precise reminder and check in the instant the 24-hour window opens.
- Use the Southwest app for the fastest check-in.
- Have your details ready so you're not fumbling when the clock strikes.
- Hold a Business Select fare if you booked one — it includes a premium position.
- Ask about family boarding, which lets adults traveling with young children board between groups A and B.
