Southwest Airlines offers two free checked bags per passenger. For more details or help, call 1-888-843-5587 and speak with a representative.

Southwest Airlines famously offered a two‑free checked bags policy for nearly six decades.

New Checked Baggage Fees

1. First checked bag: $35

2. Second checked bag: $45 

These fees now mirror rates charged by competitors such as Delta, United, and American Airlines. 

 Free Bag Allowance by Status

Despite the overall change, certain travelers still enjoy complimentary or reduced baggage fees:

1. Business Select fare passengers: 2 free checked bags

2. Rapid Rewards A‑List Preferred: 2 free checked bags

3. Rapid Rewards A‑List (standard elite status): 1 free checked bag

4. Rapid Rewards cardholders (primary cardmember + up to 8 others on same reservation): 1 free checked bag per person

Weight & Size Limits

1. Checked bags must weigh no more than 50 lbs (23 kg)

2. Must measure a maximum of 62 linear inches (L+W+H) or 157 cm Too heavy or oversized baggage incurs additional fees, and Southwest enforces strict maximums:

3. Bags weighing 51–100 lbs: extra fee (varies with class)

4. Oversized items exceeding 62 but under 80 inches: oversized fee applies 

Some third-party summaries report heavier bags may be charged $75–$125—but official Southwest documentation suggests the higher excess fees may be up to $150 or $200, depending on type and region. 

 Carry‑On Policy

1. One full-size carry‑on (stowed in overhead bin) plus one personal item (under-seat) allowed per passenger.

2. Carry-on size limits: typical maximum ~10×16×24 inches overhead; personal item must fit under seat (e.g. laptop or tote).

Additional Items & Sports Equipment

1. Assistive devices, outer garments, food in disposable packaging, and child restraint systems do not count toward counted carry-on limits. 

2. Some sports gear (like skis or golf clubs) can count as one checked bag if within size/weight limits.

3. Oversized gear like large bicycles or surfboards may incur additional fees depending on oversize or weight) 

Strategic Implications & Customer Reaction

1. The baggage fee introduction marks a major departure from Southwest’s brand identity and slogan “bags fly free.”

2. Behavioral economists underscore that customers view the loss of free bags as significantly more negative than the actual dollar cost due to the endowment effect. The change may erode loyalty and trust. 

3. Southwest leadership framed the shift as a "low risk" move that aligns with industry norms, aimed at boosting revenue amid cost pressures. 

Tips for Travelers

1. Book flights before May 28, 2025 to retain the old policy if you don't qualify for free bags afterward. 

2. Pack light and maximize carry‑on usage to avoid checked baggage fees.

3. Use a Southwest credit card to get one free bag if you’re not an elite member.

4. Monitor your fare class and loyalty status when booking to understand whether you qualify for free bags.
