Southwest Airlines Seat Selection Guide for Families and Groups

Author : Esyfly Hub | Published On : 11 May 2026

Traveling with children, relatives, or friends can be exciting, but many passengers wonder how southwest airlines seat selection works since Southwest Airlines is known for its unique open seating policy. Unlike most airlines, Southwest does not assign seats in advance. Instead, passengers choose any available seat after boarding the aircraft.

For families and groups, understanding southwest airlines seat selection is essential to sitting together and enjoying a stress-free trip. This guide explains how the process works and offers practical tips to improve your chances of finding seats together.

How Southwest Airlines Seat Selection Works

The southwest airlines seat selection process is based on boarding groups rather than assigned seat numbers. After checking in, each traveler receives:

  • A boarding group (A, B, or C)

  • A position number (such as A25 or B12)

Passengers board in order and may select any open seat once on the plane.

The earlier your boarding position, the more seating choices you will have.

Check In Exactly 24 Hours Before Departure

One of the most important strategies for successful southwest airlines seat selection is checking in as soon as online check-in opens, which is exactly 24 hours before departure.

Early check-in can provide:

  • Better boarding positions

  • More available seats

  • Higher chances of sitting with family or friends

Using the Southwest Airlines app makes the process quick and convenient.

Family Boarding Benefits

Southwest offers special Family Boarding between Groups A and B for:

  • Up to two adults traveling with a child age six or younger

This feature is one of the most helpful parts of southwest airlines seat selection, allowing families with young children to board early and find seats together.

Families with older children are not guaranteed Family Boarding and should prioritize early check-in or boarding upgrades.

EarlyBird Check-In

EarlyBird Check-In is an optional paid service that automatically checks you in before the 24-hour window.

Benefits include:

  • Improved boarding position

  • Reduced stress

  • Better chances for group seating

For larger groups, EarlyBird can significantly enhance the southwest airlines seat selection experience.

Upgraded Boarding

If better positions are still available, travelers can purchase Upgraded Boarding at the airport or through the app.

This upgrade typically secures a spot in the A1–A15 boarding positions, giving groups excellent access to available seats.

Tips for Groups Traveling Together

To maximize success with southwest airlines seat selection:

  • Book all travelers on one reservation

  • Check in exactly 24 hours before departure

  • Consider EarlyBird Check-In

  • Arrive at the gate early

  • Board promptly when your group is called

Even if your boarding positions are separated, passengers often rearrange to help families and groups sit closer together.

Best Seats for Families

Families often prefer:

  • Window seats for children

  • Aisle seats for easier access

  • Seats near the front for faster deplaning

  • Rear seats, which may have more open options during boarding

The best seats depend on your travel priorities and how many people are in your group.

What If Your Group Cannot Sit Together?

On full flights, it may be difficult for every member of a large group to sit together. In these cases:

  • Split into smaller groups

  • Ask fellow passengers politely

  • Use Family Boarding when eligible

Southwest flight attendants may offer guidance but generally do not assign seats.

Final Thoughts

The southwest airlines seat selection process is different from traditional assigned seating, but families and groups can still sit together with proper planning. By checking in early, using Family Boarding, and considering EarlyBird or Upgraded Boarding, travelers can greatly improve their chances of securing seats together.
