Understanding Southwest Open Seating & Boarding Process: A Complete Guide for First-Time Flyers

If you’re used to traditional airlines where you pick your seat in advance, flying with Southwest Airlines can feel completely different. Instead of assigned seating, Southwest uses an open seating system combined with a unique boarding process that determines your seat.

This guide will help you fully understand how it works, why it exists, and how to use it to your advantage. Whether you’re a first-time flyer or just want better seats, this article will break down everything in a simple, practical way.

What Is Southwest Open Seating?

Southwest’s open seating policy means:

  • No assigned seats
  • No seat selection during booking
  • You choose any available seat when you board

Instead of picking a seat ahead of time, your boarding position determines how early you get on the plane—and therefore how many seat choices you have.

Why Southwest Uses Open Seating

Southwest’s system is designed to:

  • Speed up boarding
  • Reduce operational costs
  • Keep fares lower
  • Improve efficiency

Unlike traditional airlines that assign seats and deal with seat changes, this system allows passengers to board quickly and choose seats on their own.

How Southwest Boarding Process Works

The boarding process is built around groups and numbers, not seat assignments.

Step 1: Get Your Boarding Position

When you check in, you receive a boarding position like:

  • A1–A60
  • B1–B60
  • C1–C60

This determines when you board.

Step 2: Boarding Groups Explained

Group A (Best Seats)

  • First to board
  • Access to aisle, window, and front seats
  • Ideal for frequent flyers or early check-ins

Group B (Decent Options)

  • Still good seat availability
  • Middle seats less likely early

Group C (Limited Choices)

  • Often middle seats only
  • May need to sit apart from travel companions

Step 3: Line Up by Number

At the gate, you’ll see numbered markers (1–60).
Passengers line up in order within their group.

Example:

  • If you’re B15 → stand near marker 15 in the B group

This organized system reduces confusion and speeds up boarding.


Step 4: Choose Your Seat Onboard

Once onboard:

  • Pick any open seat
  • Store your luggage
  • Sit down quickly

There are no reserved seats—first come, first served.

Want fewer disturbances?

  • Window seats

3. Travel Light for Faster Boarding

Passengers who:

  • Don’t struggle with overhead bins
  • Move quickly

…get better seat selection opportunities.


4. Watch for Empty Rows

If the flight isn’t full:

  • Look for rows with only one passenger
  • You may get extra space

Seat saving is unofficial and controversial:

  • Some passengers try to save seats
  • It’s not enforced policy

If needed, politely ask or choose another seat.

Always remember: you choose your seat onboard.


3. Ignoring Boarding Position Importance

Your boarding position is everything.
