Is Southwest Airlines a Good Airline? Everything You Need to Know

If you’re considering flying with Southwest Airlines (southwestair), you’re not alone. Known for its friendly service and flexible policies, many travelers wonder, “Is Southwest a good airline?” The answer is yes—for those who value free checked bags, no change fees, and a laid-back flying experience.

While some refer to it as “South Western Airlines”, the official name is Southwest Airlines, and it’s one of the most popular low-cost carriers in the U.S.

Does Southwest Assign Seats?
A common question passengers ask is: “Does Southwest assign seats?” The answer is no. Southwest uses an open seating policy.

• Passengers board in groups (A, B, or C) based on when they check in.
• Once on the plane, you can choose any open seat—there are no assigned seats in advance.

Southwest Airlines Seating Policy (Current):
Southwest doesn’t assign seats ahead of time.

• You pick your seat after boarding.
• Boarding order is based on check-in time—check-in opens 24 hours before your flight.
• You get a boarding group (A, B, or C) and number (1–60).
• Earlier check-in = better boarding spot = more seat choices.
• You can pay for EarlyBird Check-In or buy a Business Select fare for earlier boarding.

What’s Changing (2025–2026):
In late 2025, Southwest will start offering assigned seating during booking. These flights will begin in 2026. You’ll be able to choose from:

• Extra Legroom Seats – Front or exit rows, with more space.
• Preferred Seats – Standard legroom but closer to the front or exits.
• Standard Seats – Spread throughout the cabin with regular legroom.

Frequent flyers like A-List members and Business Select passengers will get early access to better seats. Companion Pass holders can share these benefits with their travel companion.
