Southwest permits each passenger to bring one carry-on bag and one personal item at no additional charge. The carry-on bag should fit in the overhead compartment, while the personal item, such as a purse, briefcase, laptop bag, or small backpack, must fit under the seat in front of you. This policy allows for a total of two items per passenger.

2. Checked Baggage Policy
Southwest’s checked baggage policy is notably generous:
- First and Second Checked Bags: Both are free of charge, provided they do not exceed 50 pounds in weight and 62 inches in total dimensions (length + width + height).
- Third and Additional Checked Bags: Each incurs a fee of $150 per bag.
- Overweight and Oversized Bags:
- Overweight Bags (51-70 lbs.): Subject to a $150 fee per bag.
- Overweight Bags (71-100 lbs.): Subject to a $200 fee per bag.
- Oversized Bags (over 62 inches up to 80 inches): Subject to a $200 fee per bag.
- Combination of Overweight and Oversized: If a bag is both overweight and oversized, only the higher fee applies.
3. Special Items and Sporting Equipment
Southwest accommodates various special items and sporting equipment, often for a fee of $75 per item. These items include:
- Sporting Equipment: Such as windsurfing boards, surfboards, vaulting poles, non-motorized bicycles (62 inches or less and less than 50 pounds), life rafts, javelins, and kayaks.
- Large Media Camera Equipment: Subject to a $75 fee per item.
4. Military Personnel
Active duty military personnel traveling on orders are allowed to check up to five bags free of charge, with each bag adhering to the standard size and weight limitations. This benefit underscores Southwest’s commitment to supporting military members.
5. Pet Travel
Southwest accepts small vaccinated domestic cats and dogs to travel as pets. All in-cabin pets must be carried in an appropriate carrier. Each pet carrier counts as a carry-on or personal item. The pet fare is subject to change at any time.
6. Pro Tips for a Smooth Baggage Experience
To ensure a hassle-free experience with Southwest’s baggage policy, consider the following tips:
- Weigh and Measure Your Bags: Before heading to the airport, weigh your checked bags and measure their dimensions to ensure they comply with Southwest’s allowances. This proactive step can help you avoid unexpected fees.
- Use a Luggage Scale: Investing in a portable luggage scale can be a game-changer, especially for international travelers. It allows you to check your bag’s weight at home, ensuring it meets the airline’s requirements.
- Pack Strategically: Distribute weight evenly across your luggage to prevent any single bag from exceeding the weight limit. Utilize carry-on allowances for essential items to reduce the number of checked bags.
- Stay Informed: Baggage policies can change. Regularly check Southwest’s official website or contact customer service for the most current information before your trip.
- Consider EarlyBird Check-In: For a fee, Southwest offers EarlyBird Check-In, which automatically checks you in 36 hours before your flight, potentially securing better boarding positions and overhead bin space.
- Be Mindful of Prohibited Items: Ensure that your carry-on and checked baggage do not contain prohibited items, such as spare lithium-ion batteries, which are not allowed in checked luggage.
- Utilize Southwest’s Baggage Allowance: Take full advantage of the two free checked bags per passenger. This policy can lead to significant savings, especially for families or travelers with substantial luggage.
- Plan for Special Items: If you’re traveling with special items like sporting equipment or musical instruments, contact Southwest in advance to understand any specific requirements or fees associated with these items.
- Keep Receipts and Documentation: In case of baggage issues, having receipts and documentation can be helpful for claims or inquiries.

7. More Details About Southwest’s Baggage Policy
While the core aspects of Southwest Airlines’ baggage policy are straightforward, let’s dive a bit deeper into certain areas for a fuller understanding of what you can expect when flying with Southwest.
A. Carry-On Bag Size and Restrictions
The carry-on bag is a crucial part of your travel experience, especially for those who like to keep their essentials close. Southwest Airlines allows passengers to bring one carry-on bag as long as it meets the size requirements:
- Dimensions: The carry-on must fit within the limits of 10 inches high x 16 inches wide x 24 inches long. This is the maximum size that can be placed in the overhead compartment. If your carry-on exceeds these dimensions, it may need to be checked in, which could result in additional fees. Make sure to measure your bag before arriving at the airport.
- Liquids: Similar to TSA guidelines, you are allowed to bring liquids, gels, and aerosols in your carry-on as long as they follow the 3-1-1 rule. This means that each liquid must be in a container of 3.4 ounces or less, and all containers must fit in a quart-sized, clear, resealable bag.
B. Personal Items: What Can You Bring?
Southwest defines a personal item as an item that can fit under the seat in front of you, and the possibilities are endless. Here are some examples of what counts as a personal item:
- A purse, laptop bag, or backpack
- A diaper bag
- A small camera bag or briefcase
- A small pet carrier (as long as it fits under the seat)
If you are trying to save space and avoid paying extra baggage fees, making sure your personal item is well-organized can be helpful. For instance, you can pack all your travel essentials, like your wallet, medications, electronics, and snacks, in your personal item so you won’t have to rummage through your carry-on bag while on the plane.
C. Excess Baggage Fees
Though Southwest Airlines offers two free checked bags, you may end up needing more, especially if you’re traveling with a family, for business, or on a long trip. If you’re planning to check more than two bags, keep in mind the additional fees involved:
- Third and Additional Bags: After the second checked bag, you’ll be charged $150 for each additional bag.
- Oversized Baggage Fees: If your checked bag exceeds the allowed 62 inches (length + width + height), you’ll face a $200 fee. Make sure to measure your bag before checking it in, as oversized fees are not refundable.
- Overweight Bags: If your checked bag exceeds the weight limit of 50 pounds, it can incur an additional charge:
- Bags between 51 and 70 pounds will be charged an additional $150.
- Bags between 71 and 100 pounds will be charged $200.
If you know your bag is likely to be heavy, it’s always best to redistribute items into multiple bags or make use of your carry-on allowance to prevent excessive charges. From my own personal experience, packing strategically can really save you from unexpected baggage fees.
D. Luggage Restrictions: What’s Not Allowed?
While Southwest Airlines allows a wide variety of items to be packed in your luggage, there are several prohibited items. Some of the common items you shouldn’t attempt to pack in your checked bags include:
- Explosives, flammable liquids, or gases: This includes items like gasoline, fireworks, and camping fuel.
- Lithium-ion batteries: These are prohibited in checked baggage unless they are installed in a device (such as your phone or laptop). If you’re carrying spare batteries, they must go in your carry-on bag.
- Perishable food: While you can carry non-perishable snacks, items like fresh fruits, vegetables, and meats should be kept in mind if you’re packing food for a long journey.
Always review Southwest’s specific guidelines to ensure you’re not packing any restricted items. It’s always best to err on the side of caution, as violations can lead to fines or removal of the item from your baggage.
E. International Travel Baggage Considerations
For international flights, Southwest Airlines maintains the same baggage allowance as domestic flights, which means you’re entitled to check two bags free of charge, each within the 50-pound weight limit. However, the general baggage rules may differ slightly depending on your departure or arrival airport, particularly when flying to or from destinations with customs regulations.
When flying internationally, it’s a good idea to:
- Review country-specific regulations: Some countries have strict baggage and security policies that may vary from Southwest’s standard.
- Prepare for longer delays: International baggage handling can take longer than domestic, so don’t be in a rush to collect your bags immediately after arrival.
- Plan for longer travel times: If you’re traveling internationally, you may want to add additional layers of clothing or important items to your carry-on, especially in case your checked luggage is delayed.
F. Traveling With Special Items
Southwest Airlines is well-known for accommodating passengers traveling with special items, like musical instruments, golf clubs, skis, and other equipment. In general, you’ll need to ensure that your special items are packed properly to avoid damage, and depending on the size, they might count as checked luggage or require a separate fee.
- Musical Instruments: If your instrument is small enough to fit in the overhead compartment, you can carry it on for free. Otherwise, you’ll need to check it. The fee for checking a musical instrument is typically $75.
- Sports Equipment: Whether you’re a golfer, surfer, or cyclist, Southwest Airlines allows a range of sports equipment to be checked, as long as they are within the size and weight restrictions.
- Large, Fragile Items: If you’re traveling with something fragile, such as artwork or an antique, make sure to alert Southwest personnel to properly handle your items. You can also bring a packing container that ensures safe transport.
G. Military and Other Special Considerations
Southwest Airlines offers a fantastic benefit to military members and their dependents traveling on active duty orders. Active-duty military personnel can check up to five bags free of charge. Additionally, Southwest is often praised for its compassionate policies in dealing with passengers who have medical needs or are traveling with service animals. Always reach out in advance to confirm the necessary accommodations.
H. Southwest’s Baggage Claim Process
If your checked bag does not arrive at your destination or is delayed, Southwest has an efficient baggage claim process to help resolve any issues:
- Report the Issue Immediately: The sooner you report lost baggage, the quicker Southwest can initiate a search. Make sure to file a claim within 4 hours of your flight’s arrival at the airport.
- Tracking Your Bags: Southwest has a tracking system that allows passengers to check the status of their lost baggage via the airline’s website or through customer service.
- Compensation for Lost Baggage: In cases where your baggage is lost permanently, Southwest will provide compensation for essential items you need to buy while waiting for your luggage to be recovered.
