Southwest Airlines Checked Baggage Fees: What You Need to Know

Southwest Airlines has long been known for its customer-friendly policies, particularly its unique “Bags Fly Free” offering, which allowed passengers to check two bags at no additional cost. However, beginning May 28, 2025, Southwest will implement checked baggage fees for the first time in its history. This move marks a significant shift in the airline’s approach and aligns it more closely with other major U.S. carriers. Additionally, Southwest is set to transition from open seating to assigned seating, further reshaping its passenger experience.

The History of ‘Bags Fly Free’

For decades, Southwest Airlines stood out in the airline industry by offering two free checked bags for every passenger. This policy was a key differentiator, attracting budget-conscious travelers and fostering strong customer loyalty. Families, business travelers, and frequent flyers often chose Southwest over competitors specifically because they could avoid costly baggage fees.

While other airlines steadily increased fees for checked luggage, Southwest remained committed to its free baggage policy. However, rising operational costs and industry competition have led to a reevaluation of this approach.

Why Is Southwest Introducing Baggage Fees?

Several factors contributed to Southwest’s decision to introduce checked baggage fees:

1. Revenue Growth – Baggage fees have become a significant source of revenue for airlines. Southwest’s competitors generate billions of dollars annually from these fees, and Southwest now seeks to capitalize on this revenue stream.

2. Financial Pressure – Investors and financial analysts have long urged Southwest to explore additional revenue opportunities. The airline has faced increasing financial pressures due to fuel costs, inflation, and competition from low-cost carriers.

3. Operational Efficiency – By charging for checked bags, Southwest hopes to encourage passengers to pack lighter, which could reduce loading and unloading times, improve turnaround efficiency, and streamline operations.

4. Alignment with Industry Standards – Nearly every major airline in the U.S. charges for checked bags, and Southwest’s move brings it in line with industry norms.

What Will the New Baggage Fees Look Like?

Although Southwest has not yet announced specific pricing, the structure is expected to be similar to those of other major airlines. Here’s what passengers can likely expect:

• First Checked Bag Fee – A flat rate for the first checked bag, likely comparable to fees charged by competitors.
• Second Checked Bag Fee – A slightly higher fee for an additional checked bag.
• Oversized and Overweight Bag Fees – Additional charges for bags exceeding weight or size limits.
• Exemptions for Certain Travelers – Business Select passengers, loyalty program members, and Southwest-branded credit card holders may receive discounts or free checked baggage allowances.

Changes to Southwest’s Seating Policy

In addition to baggage fee changes, Southwest is also shifting from its signature open seating model to an assigned seating system. Under the current model, passengers board in groups and select any open seat upon entering the plane. This has been a defining feature of Southwest’s service for years.

However, customer feedback has suggested that many travelers prefer the certainty of assigned seats. Assigned seating is expected to reduce boarding anxiety, improve efficiency, and enhance the overall passenger experience. The transition to this new system is expected to take effect in early 2026.

Customer Reactions and Industry Impact

Southwest’s announcement has received mixed reactions from passengers:

• Positive Reactions – Some travelers welcome the move to assigned seating, as it eliminates the stress of securing preferred seats. Others understand that baggage fees are a necessary adjustment in today’s airline industry.
• Negative Reactions – Many loyal Southwest customers feel disappointed by the loss of the “Bags Fly Free” policy, viewing it as a move away from the airline’s customer-first approach.

From an industry perspective, Southwest’s decision to introduce baggage fees is expected to influence competitors. Some airlines may enhance their own baggage policies to attract former Southwest loyalists, while others may adjust pricing strategies to remain competitive.

How Passengers Can Prepare

If you’re planning to fly Southwest after May 28, 2025, here are some tips to prepare for these changes:

• Monitor Airline Updates – Stay informed about the official fee structure and potential exemptions.
• Budget for Additional Costs – Factor in baggage fees when comparing ticket prices to ensure accurate cost planning.
• Optimize Packing Strategies – Consider packing lighter or utilizing carry-on options to minimize checked baggage expenses.
• Explore Loyalty Programs – If you frequently fly with Southwest, look into loyalty programs or airline credit cards that may offer baggage fee waivers.

Conclusion

Southwest Airlines’ introduction of checked baggage fees and assigned seating marks a major shift in its operational model. While these changes may disappoint long-time customers, they reflect broader trends in the airline industry and are aimed at increasing revenue and efficiency. As travelers adjust to these updates, Southwest will need to balance profitability with maintaining its reputation for customer-friendly service.
