Southwest Airlines: Built on the Low-Cost, High-Value Model

Southwest's entire business model was built around a simple idea: strip away the unnecessary costs and pass the savings to customers. Since its founding, the airline has pioneered practices now taken for granted across the industry — point-to-point routing instead of the hub-and-spoke model, rapid turnaround times, and a single aircraft type (the Boeing 737) for operational simplicity. The airline's commitment to keeping costs low while maintaining industry-leading customer satisfaction has earned it decades of consistent profitability and loyalty from millions of travelers.

Southwest operates primary hubs at Dallas Love Field (DAL) — its original home and largest hub — along with major focus cities at Chicago Midway (MDW), Las Vegas (LAS), Baltimore/Washington (BWI), Phoenix (PHX), Denver (DEN), Houston Hobby (HOU), and Los Angeles (LAX). The airline's point-to-point network means many routes bypass major connecting hubs entirely, delivering faster, more direct travel for passengers on popular leisure and business corridors.

Bags Fly Free: Southwest's Most Famous Policy

Perhaps no policy is more synonymous with Southwest Airlines than "Bags Fly Free." While every other major U.S. carrier charges $35–$40 for the first checked bag and $45–$50 for the second, Southwest includes two free checked bags for every passenger on every fare — no exceptions, no elite status required. For a family of four checking bags, this represents a savings of $280–$320 compared to legacy carriers, often making Southwest the true lowest-cost option even when its base fares appear slightly higher. Each checked bag may weigh up to 50 lbs and measure up to 62 linear inches combined. Call +1 (888) 457-7599 for assistance with baggage or oversized items.

No Change Fees: True Flight Flexibility

Southwest Airlines was the first major U.S. carrier to permanently eliminate change fees, a policy that has since been adopted by competitors — but Southwest remains the gold standard for flexibility. Key details:

• Wanna Get Away / Wanna Get Away Plus — can be changed any time without a fee; if the new fare is lower you receive the difference as a transferable travel credit (Plus tier)
• Anytime — fully refundable to the original payment method; can be changed or cancelled at any time for any reason
• Business Select — fully refundable and changeable, with priority boarding (A1–A15), a premium drink coupon, and bonus Rapid Rewards points
• All tickets can be cancelled within 24 hours of purchase for a full refund regardless of fare type

Open Seating: Southwest's Unique Boarding System

Southwest is the only major U.S. airline that does not assign seats. Instead, passengers are assigned a boarding group (A, B, or C) and a position number (1 through 60+) when they check in, beginning 24 hours before departure. Passengers board in order and may sit in any available seat. Tips for getting the best seat:

• Check in exactly at the 24-hour mark for the earliest boarding position in your group
• Purchase EarlyBird Check-In ($15–$25 per segment) for automatic check-in 36 hours before departure
• Book Business Select for guaranteed A1–A15 boarding — the front of the plane every time
• Families with children 6 and under board between groups A and B regardless of check-in position

Rapid Rewards: Southwest's Loyalty Program

Rapid Rewards is Southwest Airlines' loyalty program and one of the most generous in the domestic airline industry. Unlike programs that award miles based on distance flown, Rapid Rewards awards points based on the fare paid — meaning higher-priced fares earn more points proportionally. Key program highlights:

• Points never expire as long as you have qualifying account activity
• Award redemption on any available Southwest seat with no blackout dates and no seat restrictions
• The Companion Pass — earned by accumulating 135,000 qualifying points in a calendar year — allows one designated companion to fly free (plus taxes and fees) on every Southwest flight for the remainder of that year and the full following year
• A-List elite tier (25 qualifying one-way flights or 35,000 tier qualifying points per year) unlocks priority boarding, a 25% point bonus, and same-day standby
• A-List Preferred (50 qualifying one-way flights or 70,000 tier qualifying points) adds a 100% point bonus, free in-flight Wi-Fi, and dedicated phone support

How to Find the Best Southwest Airlines Fares

• Book 3–6 weeks in advance for domestic routes; Hawaii and international destinations 8–10 weeks ahead
• Check Southwest's website directly — the airline does not distribute fares through third-party booking sites
• Watch for Southwest's periodic sale events, typically held in January, May, and September
• Use Rapid Rewards points for peak travel when cash fares are highest — points redemptions offer the best value during high-demand periods
• Consider EarlyBird Check-In to secure a good boarding position without the stress of the 24-hour check-in
• Call +1 (888) 457-7599 — our agents can monitor fare changes and rebook you at a lower price if one becomes available after your purchase
