If you're flying Southwest, you're in luck, as their baggage policy has historically been quite generous. However, recent changes mean it's more important than ever to understand the limits!

| How Many Pounds Can A Suitcase Weigh On Southwest Airlines |
Step 1: Engage with Your Luggage! (And Understand the Basics)
Before we dive into the nitty-gritty, let's start with a crucial first step: Get to know your luggage! Seriously, pick it up. Is it heavy when empty? What type of bag is it (checked, carry-on, personal item)? Understanding the type of luggage you're planning to bring is the first key to figuring out the weight limits.
Southwest Airlines, while famous for its "Bags Fly Free" policy, has implemented some changes recently. As of May 28, 2025, the landscape for free checked bags has shifted. Now, most travelers will face fees for their first and second checked bags. However, there are still ways to qualify for free checked bags, which we'll cover.
For Checked Baggage: Southwest Airlines generally allows checked bags to weigh up to 50 pounds (23 kg) each. Beyond this weight, you'll incur additional fees.
For Carry-on Bags: Southwest does not have a specific weight restriction for carry-on items. However, they must fit in the overhead bin.
For Personal Items: Similar to carry-on bags, there's no stated weight limit for personal items, but they must fit under the seat in front of you.
Now that you have a general idea, let's get into the specifics!
Step 2: Checked Baggage - The 50-Pound Rule
This is where the majority of travelers need to pay close attention. For each checked bag, the standard weight limit on Southwest Airlines is 50 pounds (approximately 23 kilograms).
Tip: Reread sections you didn’t fully grasp.
Sub-heading 2.1: The Per-Bag Limit
It's important to remember that this 50-pound limit applies to each individual checked bag, not your total luggage weight. So, if you're checking two bags, each of them must be 50 pounds or less.
Sub-heading 2.2: Overweight Baggage Fees
What happens if your bag tips the scales over 50 pounds? Southwest imposes an overweight baggage fee. This fee is typically an additional $75 for bags weighing between 51 and 100 pounds (23-45 kg).
-
Important Note: Any item weighing over 100 pounds (45 kg) will not be permitted as checked baggage and may need to be shipped as air cargo. This is crucial for unusually heavy items.
Sub-heading 2.3: Oversized Baggage Considerations
While this post focuses on weight, it's worth a quick mention of size. In addition to weight, checked bags also have a standard size limit of 62 linear inches (length + width + height). If your bag exceeds this, it's considered oversized and will also incur a fee, usually an additional $75 for bags between 63 and 80 inches. If a bag is both overweight and oversized, generally only one $75 fee applies, assuming it doesn't exceed 100 lbs.
Step 3: Carry-On and Personal Items - Freedom from Weight Limits (Mostly)
Good news for those who prefer to keep their essentials close! Southwest Airlines is quite generous when it comes to carry-on and personal item weight.
Sub-heading 3.1: Carry-On Bag Specifications
Southwest allows one carry-on bag per passenger. While there's no stated weight limit, the bag must adhere to specific dimensions to fit in the overhead bin. These dimensions are typically 24 inches (L) x 16 inches (W) x 10 inches (H), including wheels and handles. The key here is that it needs to fit, regardless of weight.
Tip: Context builds as you keep reading.
Sub-heading 3.2: Personal Item Details
In addition to your carry-on, you're allowed one personal item. This item should fit under the seat in front of you. Again, there's no explicit weight limit. Common examples include purses, briefcases, laptop bags, small backpacks, and even neck pillows. The general dimensions are around 18.5 x 13.5 x 8.5 inches.
Step 4: Who Still Gets Bags Fly Free? (The Exceptions!)
As mentioned, Southwest's "Bags Fly Free" policy has been adjusted for most travelers. However, certain passengers can still enjoy the benefit of checking bags without a fee. This is a critical step for understanding if you qualify for cost savings.
Sub-heading 4.1: Business Select and A-List Preferred Members
If you're a frequent Southwest flyer, your loyalty can pay off. Business Select fare holders and Rapid Rewards A-List Preferred members continue to receive two free checked bags. This is a significant perk for those who travel frequently with Southwest.
Sub-heading 4.2: A-List Status Holders and Southwest Credit Card Users
Rapid Rewards A-List members and those who hold eligible Southwest Rapid Rewards Credit Cards can check one bag for free. This is a great benefit for many travelers. Always check the specific terms and conditions of your credit card for details.
Sub-heading 4.3: Active-Duty Military Personnel
 |
Southwest Airlines offers a fantastic benefit to active-duty military personnel. With a current, valid military ID, active-duty military passengers are exempt from the two-piece baggage limit and will not be subject to excess, oversize, or overweight baggage charges. This applies as long as no single piece of baggage exceeds 100 pounds (45 kg) in weight and 80 inches (203 cm) in size. This is a huge advantage for military travelers.

Step 5: Packing Smart to Avoid Fees (Practical Tips)
Now that you know the limits, let's talk about how to pack strategically to stay within them.
Sub-heading 5.1: Weigh Your Bags at Home
This is perhaps the most crucial step for avoiding last-minute stress. Invest in a portable luggage scale. They are inexpensive and can save you a significant amount of money and hassle. Weigh your bag as you pack, and adjust as needed.
Sub-heading 5.2: Strategic Packing Techniques
-
Roll, Don't Fold: Rolling your clothes can save space, allowing you to fit more without necessarily adding excessive weight.
-
Wear Your Heaviest Items: If you're close to the limit, wear your bulkiest shoes or heaviest jacket on the plane.
-
Utilize Your Personal Item and Carry-On: Remember, these don't have weight limits. Pack heavier items like books, electronics, or shoes in your carry-on or personal item if you're worried about your checked bag's weight.
-
Travel-Sized Toiletries: Those full-sized shampoo bottles can add up! Opt for travel-sized versions or solid toiletries.
-
Consider Shipping: For extremely heavy or oversized items, especially if you're staying for an extended period, consider shipping them via a courier service. It might be more cost-effective than airline fees.
Sub-heading 5.3: Know When to Splurge
Sometimes, paying the fee might be unavoidable. If you know you'll be over the limit, factor the fee into your travel budget. It's better to be prepared than surprised at the airport.
Step 6: Special Baggage - Musical Instruments and Sports Equipment
Southwest has specific policies for certain items like musical instruments and sports equipment, which can sometimes exceed standard baggage dimensions or weight.
Sub-heading 6.1: Musical Instruments
Tip: Use the structure of the text to guide you.
-
Carry-on: Smaller instruments that fit within carry-on dimensions (24" x 16" x 10") can be brought on board if space is available. Larger instruments that don't fit carry-on dimensions may still be allowed in the cabin if they fit in an overhead bin or under a seat and there's space.
-
Purchasing a Seat: For larger instruments that can't be stowed, you can purchase a separate seat for them. They must fit in the seat and be secured.
-
Checked Baggage: Instruments can be checked as part of your allowance. If they exceed 62 linear inches or 50 pounds, overweight/oversize fees may apply. Instruments over 150 inches or 165 pounds will not be accepted as checked baggage.
Sub-heading 6.2: Sports Equipment
Many types of sports equipment (golf clubs, skis, surfboards, bicycles, etc.) are accepted as checked baggage.
-
They generally count towards your checked baggage allowance.
-
If they exceed the 50-pound weight limit or 62-inch size limit, overweight/oversize fees will apply (typically $75).
-
Some specialized items, like surfboards to/from Hawaii (inter-island only), might have different rules. Always check Southwest's official website for the most up-to-date and specific rules for your particular equipment.
