Southwest Airlines Checked Baggage Policy +1-866-666-0215

Southwest Airlines is one of the few U.S. airlines that still offers an incredibly generous Southwest Airlines Checked Baggage Policy—allowing passengers to check two bags free of charge on every flight. Whether you’re flying for business, vacation, or moving with your belongings, Southwest’s policy can save travelers hundreds of dollars compared to competitors.

1. Southwest Airlines Checked Baggage Allowance

Southwest Airlines’ baggage allowance is one of the most customer-friendly in the airline industry.

Two checked bags per passenger – FREE

Applies to all ticket types and all destinations

No need for elite status or special memberships to qualify

This policy applies to both domestic and international flights operated by Southwest Airlines.

2. Size and Weight Limits for Checked Bags

Even though the first two checked bags are free, they must meet specific size and weight requirements to avoid extra charges.

Maximum weight: 50 pounds (22.68 kg) per bag

Maximum size: 62 linear inches (length + width + height)

Bags exceeding either the weight or size limit will incur additional fees.

3. Excess Baggage Fees on Southwest Airlines

If you need to bring more than two checked bags or your luggage is oversized or overweight, Southwest will charge additional fees:

  Baggage Type
Fee (One-Way)
Third (or additional) checked bag
$75
Overweight bag (51–100 lbs)
$75
Oversized bag (63–80 linear inches)
$75
Note: Bags over 100 pounds or 80 linear inches are not accepted as checked baggage and must be shipped as cargo.

4. Special Items & Sports Equipment

Southwest Airlines accepts many special items as part of your checked baggage allowance, including:

Sports gear: skis, snowboards, golf clubs, surfboards, fishing rods, bicycles (packing rules apply)

Musical instruments: can be checked if properly packed

Child equipment: car seats and strollers are checked for free in addition to your allowance

Some items, like surfboards or bicycles, may incur oversize fees unless traveling to specific destinations (e.g., surfboards to/from Hawaii are exempt).

5. Southwest Airlines Military Baggage Policy

Southwest offers special baggage allowances for active-duty U.S. military members:

Two free checked bags weighing up to 100 pounds each and measuring up to 80 linear inches

Additional free bags when traveling on official orders

Must present valid military ID at check-in

6. International Flights Checked Baggage Rules

Southwest Airlines operates flights to Mexico, Central America, and the Caribbean. The same two free checked bags policy applies internationally, but travelers should be aware of:

Customs regulations at arrival

Agricultural restrictions (especially when bringing food)

Possible inspection delays

7. Prohibited Items in Checked Baggage

Southwest follows TSA and FAA regulations on dangerous goods. Prohibited items include:

Explosives and flammable liquids

Certain lithium batteries

Weapons without proper declaration and packaging

Perishables without proper insulation

8. Tips to Avoid Baggage Fees on Southwest Airlines

Although Southwest is generous with baggage, you can still incur charges if you exceed limits. Here’s how to avoid them:

Weigh your bags at home to stay under 50 pounds

Measure oversize items before heading to the airport

Pack smartly to fit into two bags instead of three

Use lightweight luggage to maximize your packing weight

Check special item policies in advance to avoid surprises

9. Lost, Delayed, or Damaged Bags

If your checked baggage is delayed, lost, or damaged, Southwest recommends:

Report it immediately to the baggage service office at your arrival airport

Provide your baggage claim ticket and a description of the bag

Keep receipts for essential items you need while your bag is missing

For domestic travel, compensation is capped at $3,800 per passenger under U.S. Department of Transportation regulations.

10. Why Southwest’s Checked Baggage Policy Stands Out

In an industry where baggage fees are often unavoidable, Southwest Airlines’ policy saves travelers money and reduces packing stress.

Most U.S. airlines charge $35–$45 for the first bag and $45–$60 for the second—costs that Southwest passengers avoid entirely.

Families, sports teams, and long-term travelers benefit the most from this free baggage allowance.

The policy reflects Southwest’s “Transfarency®” philosophy—offering upfront pricing without hidden fees.

Conclusion

Southwest Airlines’ checked baggage policy is one of the most generous and straightforward in the airline industry. By allowing two free checked bags on every ticket, Southwest makes travel more affordable and stress-free—especially for families, long-term travelers, or anyone who needs more than just a carry-on.
