Selección de asientos Southwest Airlines is one of the most searched travel topics because Southwest Airlines uses a unique open seating system instead of assigning seats during booking. Many travelers want to know how to get the best seat, improve their boarding position, and sit together with family or friends during their flight.

In this complete 2026 guide, you’ll learn everything about Southwest Airlines seating policies, boarding groups, EarlyBird Check-In, upgraded boarding, and expert strategies that can improve your travel experience.

How Does Selección de asientos Southwest Airlines Work?

Unlike traditional airlines, Southwest Airlines does not assign seats before boarding. Instead, the airline follows an open seating policy where passengers choose any available seat after entering the aircraft.

This means:

• No assigned seats during booking
• Boarding order determines seat availability
• Earlier boarding provides better seat choices

The Selección de asientos Southwest Airlines process mainly depends on your boarding group and boarding number. Travelers who board earlier usually have access to:

• Window seats
• Aisle seats
• Front-row seats
• Exit-row seats with extra legroom

Passengers boarding later may only find middle seats available.

Southwest Airlines Boarding Groups Explained

Southwest Airlines organizes boarding into three main groups:

• Group A
• Group B
• Group C

Each group contains numbered positions such as:

• A1–A60
• B1–B60
• C1–C60

For example:

• A10 boards before A35
• B5 boards before B40

Passengers receive their boarding position after completing check-in.

Understanding this system is important for improving your Selección de asientos Southwest Airlines experience.

Since Southwest uses open seating, boarding position directly affects which seats remain available.

• Extra legroom seats
• Seats near the front
• Preferred window seats

Passengers with later boarding positions may experience:

• Limited seat choices
• Fewer overhead bin spaces

That is why experienced Southwest travelers focus heavily on getting earlier boarding numbers.
