Have you ever booked a flight on Southwest Airlines and then wondered, "Wait, how do I pick my seat?" If so, you're not alone! Southwest has a unique approach to seating that sets it apart from most other airlines. Unlike carriers that let you select your seat at the time of booking, Southwest operates on an open seating policy (though this is changing in late 2025/early 2026, which we'll address!). This means that after you book your flight, you don't actually "choose" a specific seat number in advance. Instead, your ability to snag your preferred spot depends almost entirely on your boarding position.
This comprehensive guide will walk you through everything you need to know about navigating Southwest's seating system after you've booked your flight, and how to maximize your chances of getting the seat you want.
Understanding Southwest's Open Seating Policy (Current System)
Before we dive into the steps, it's crucial to grasp the core concept: Southwest Airlines does not assign you a specific seat number when you book your ticket. Instead, they operate on a "first-come, first-served" basis for seating once you board the aircraft. Your boarding position determines when you get to board the plane, and therefore, when you get to choose your seat from what's available.
There are three main boarding groups: A, B, and C. Within each group, you'll be assigned a number (e.g., A1-A60, B1-B60, C1-C60). The lower your number, the earlier you board.
Step 1: Grasping the Importance of Your Boarding Position – This is Key!
Let's get this straight from the start: your boarding position is everything when it comes to choosing your seat on Southwest. The earlier you board, the more seat options you'll have. Want a window? An aisle? A seat near the front for a quick exit? It all hinges on getting a good boarding position.
Sub-heading: How Boarding Positions Are Determined
Your boarding position is primarily determined by two factors:
When you check in: This is the most significant factor for most passengers. Southwest opens online check-in exactly 24 hours prior to your flight's scheduled departure time. The moment check-in opens, a mad dash begins! The earlier you check in, the better your boarding position will be.
Your Fare Type/Elite Status/Add-ons: Certain fare types and add-ons come with built-in advantages for boarding. We'll explore these in more detail.
Step 2: Optimizing Your Check-In Time for a Better Boarding Position
This is where the real strategy comes into play. Since check-in time is so crucial, you need to be prepared.
Sub-heading: Set an Alarm!
Seriously, set an alarm. If you want the best possible chance at a desirable seat without paying extra, you need to check in exactly 24 hours before your flight's departure. For example, if your flight departs at 3:00 PM on a Tuesday, check-in opens at 3:00 PM on Monday. Have your confirmation number ready!
Sub-heading: Checking In Online or via the Southwest App
Online: Go to Southwest.com and look for the "Check In" tab. Enter your confirmation number, first name, and last name.
Southwest App: Download the Southwest Airlines mobile app (available on iOS and Android). It's incredibly convenient for managing your flight, checking in, and getting your mobile boarding pass. Many seasoned Southwest travelers prefer the app for its speed and ease of use.
Sub-heading: Don't Wait!
Even a delay of a few minutes after the 24-hour mark can significantly impact your boarding position, especially on popular routes or full flights. Every second counts!
Step 3: Leveraging Paid Options for Priority Boarding
If the thought of setting an alarm and racing to check in isn't your cup of tea, or if you absolutely must have a good seat, Southwest offers options to improve your boarding position for a fee.
Sub-heading: EarlyBird Check-In
What it is: EarlyBird Check-In automatically checks you in before the traditional 24-hour check-in window opens for everyone else. This typically happens 36 hours before your flight's scheduled local departure time. It essentially gives you a head start in the boarding position queue.
Benefits: While it doesn't guarantee an "A" boarding position (especially on very popular flights or if many others also purchased EarlyBird), it significantly increases your chances of getting an earlier boarding group (often A or early B), giving you more seat choices. It also provides earlier access to overhead bin space.
How to Purchase: You can usually add EarlyBird Check-In when you book your flight, or after booking through the "Change/Cancel" or "Add-ons" section of your reservation on Southwest.com or via the app. It's subject to availability and the price varies by flight.
Considerations: If you plan to purchase EarlyBird, do it as soon as possible after booking, as positions are assigned based on the time stamp of the EarlyBird purchase relative to others within the same fare product.
Sub-heading: Upgraded Boarding
What it is: Upgraded Boarding is a fantastic last-minute option if you find yourself with a later boarding position (like a B or C group) and want to improve it. It allows you to purchase an A1-A15 boarding position.
Availability: This option is typically available for purchase starting 24 hours before your flight (at the same time regular check-in opens) or at the gate on the day of travel. It's subject to availability, meaning there might not always be upgraded positions for sale, especially on full flights.
How to Purchase:
Online/App (24 hours prior): When you check in, you might see an option to purchase Upgraded Boarding if available.
At the Gate: Ask a Southwest gate agent if Upgraded Boarding is available for your flight.
Cost: The price varies depending on the route.
Step 4: Understanding Southwest Fare Types and Elite Status
Certain fare types and elite status tiers automatically come with better boarding benefits.
Sub-heading: Business Select Fares
Guaranteed A1-A15: If you purchase a Business Select fare, you are guaranteed a boarding position between A1 and A15. This means you'll be among the very first to board, allowing you prime pick of any available seat.
Other Benefits: Business Select also typically includes free inflight Wi-Fi, a complimentary premium drink, and higher Rapid Rewards earning potential.
Sub-heading: Rapid Rewards A-List and A-List Preferred Members
Priority Boarding: A-List and A-List Preferred members (Southwest's elite status tiers) automatically receive priority boarding. Their boarding positions are reserved starting 36 hours prior to the flight, typically putting them in the A group.
Other Perks: These elite tiers also come with benefits like bonus points, dedicated phone lines, and sometimes free same-day flight changes.
Step 5: Special Boarding Considerations
Southwest has policies in place for certain groups of travelers to ensure they can sit together or get the assistance they need.
Sub-heading: Family Boarding
Who it's for: Families traveling with a child six years old or younger.
When it happens: Family Boarding occurs after the "A" group has boarded and before the "B" group begins boarding.
How it works: Up to two adults traveling with a child six years or younger may board during Family Boarding. This helps ensure families can find seats together, even if their assigned boarding positions were later.
Important Note: If you and your child have "A" boarding passes, you should board with your assigned group rather than waiting for Family Boarding, as you'll have even better seat selection then.
Sub-heading: Pre-boarding
Who it's for: Passengers with disabilities or those who need specific assistance to board or find a seat.
When it happens: Pre-boarding occurs before any other boarding group (including A1-A15).
How to Request: If you require pre-boarding, speak to a Southwest gate agent before boarding begins. They will assess your needs and provide assistance.
Step 6: The Boarding Process Itself – Your Moment to Shine!
This is where all your preparation pays off.
Sub-heading: Arrive at the Gate Early
Even if you have a great boarding position, arrive at the gate with enough time to spare. This allows you to observe the boarding area and be ready when your group is called.
Sub-heading: Line Up in Order
Southwest gates typically have marked poles indicating boarding positions (e.g., A1-A30, A31-A60). When your group is called, line up in numerical order within your group.
Sub-heading: Choose Your Seat Wisely
Once you step onto the plane, it's a quick decision! Look for open seats that meet your preferences.
Window or Aisle? Scan for available rows.
Front or Back? Seats towards the front fill up quickly. If you're in a later group, you might find more options further back.
Exit Rows: These offer more legroom but have specific requirements (you must be willing and able to assist in an emergency). Flight attendants will typically verify this.
Saving Seats (Not Recommended): While you might see people try to save seats for companions with later boarding positions by placing items on them, this is generally frowned upon and not allowed by Southwest's policy. Be prepared to politely ask if a seat is taken.
Sub-heading: Don't Be Afraid to Ask a Flight Attendant
If you're having trouble finding seats together, or have a special need, politely ask a flight attendant for assistance. They are often very helpful in these situations.
Southwest's Future: Assigned Seating in Late 2025/Early 2026
IMPORTANT UPDATE: While this guide focuses on the current open seating policy, Southwest Airlines has announced a significant change! They are transitioning to an assigned seating model, with booking for assigned seats beginning in the second half of 2025 and flights operating under this model in 2026.
What this means for you: Once this change is fully implemented, the process of "choosing your seat after booking" will become more similar to other airlines. You will likely select your seat during or after the booking process, depending on your fare type.
Keep an eye out: Southwest will undoubtedly provide more details as the rollout approaches. Stay informed by checking their official website for the latest updates on their seating policies. This guide will remain relevant until the full transition to assigned seating.
