Step 2: The Golden Rule - Standard Checked Bag Weight and Size
Southwest Airlines, historically known for its generous "Bags Fly Free" policy, has made some adjustments for flights booked or voluntarily changed on or after May 28, 2025. However, the standard weight and size limits for each checked bag remain consistent.
2.1 The Weight Limit: Your Bag's Maximum Pounds
For each piece of checked luggage, the maximum weight allowed is 50 pounds (22.7 kg). This is a hard limit for standard bags. Exceeding this will incur an overweight baggage fee, which we'll discuss shortly.
2.2 The Size Limit: Measuring Up
Beyond weight, your bag also needs to fit within certain dimensions. The maximum size for a checked bag is 62 linear inches (length + width + height). Remember to include wheels and handles when you're measuring your luggage! A tape measure is your best friend here.
Step 3: "Bags Fly Free" - The Evolving Landscape
While the phrase "Bags Fly Free" has been synonymous with Southwest, it's important to understand the recent changes that took effect for flights booked or voluntarily changed on or after May 28, 2025.
3.1 Who Still Gets Free Bags?
-
Business Select fares: Passengers with Business Select tickets generally still qualify for two free checked bags.
-
Rapid Rewards A-List Preferred Members: If you've achieved A-List Preferred status, you typically retain the benefit of two free checked bags.
-
Active-duty Military Passengers: This is a fantastic benefit! Active-duty military passengers with a current, valid military ID are generally exempt from the two-piece baggage limit and will not be subject to excess, oversize, or overweight baggage charges, provided that no single piece of baggage exceeds 100 pounds in weight and 80 inches in size (L+W+H). This is a significant allowance!
-
A-List Members and Rapid Rewards Credit Card Holders: These travelers may still receive one free checked bag or a baggage credit.
Tip: Don’t overthink — just keep reading.
3.2 For Most Others: Fees Now Apply
For many other fare classes, including "Wanna Get Away" and "Wanna Get Away Plus," checked bags are no longer free for flights booked or changed on or after May 28, 2025.
-
First checked bag: A fee of approximately $35 (as of recent policy changes).
-
Second checked bag: A fee of approximately $45 (as of recent policy changes).
It's always best to check the most up-to-date information on Southwest's official website or during your booking process, as policies can be subject to change.
Step 4: Overweight and Oversized Baggage - The Cost of Going Over
What happens if your bag exceeds the standard 50-pound weight limit or the 62-linear-inch size limit? You'll face additional fees.
4.1 Overweight Baggage Fees
If your bag weighs more than 50 pounds but does not exceed 100 pounds, you'll incur an overweight baggage fee. Southwest typically categorizes this into two tiers:
-
51 - 70 pounds (23.1 - 31.8 kg): The fee is generally around $100 - $150 per item.
-
71 - 100 pounds (31.9 - 45.4 kg): The fee is generally around $200 per item.
Any item weighing more than 100 pounds will not be accepted as checked baggage and typically needs to be shipped as air cargo (which has its own set of rules and requirements).
4.2 Oversized Baggage Fees
If your bag measures more than 62 linear inches (L+W+H) but not more than 80 linear inches (203 cm), it's considered oversized. The fee for an oversized bag is generally around $200 per item.
4.3 Combined Overweight and Oversized Fees
If your bag is both overweight and oversized, you will generally be charged only one of the applicable fees, not both, as long as the bag does not exceed 100 pounds. For example, if your bag is 55 pounds and 65 inches, you'd likely pay the oversized fee (which is typically higher than the 51-70 lb overweight fee), or the overweight fee depending on the specific breakdown. Always clarify with a Southwest agent if you have a bag that falls into both categories.
Step 5: Strategies for Smart Packing and Avoiding Fees
Now that you know the rules, let's talk about how to pack like a pro and avoid those extra charges!
Tip: Slow down when you hit important details.
5.1 Weigh Your Bag Before You Leave
This is perhaps the most crucial step. Invest in a portable luggage scale. They are inexpensive and can save you a significant amount of money and stress at the airport. Weigh your bag before you leave for the airport, preferably with a little wiggle room (e.g., aim for 48-49 lbs if the limit is 50 lbs).
5.2 Distribute Weight Evenly
If you have multiple bags, try to distribute the weight as evenly as possible. Don't put all your heavy items in one suitcase if you have another that's almost empty.
5.3 Consider a Personal Item and Carry-On
Southwest also allows one carry-on bag and one personal item. While these don't have a weight limit (you just need to be able to lift your carry-on into the overhead bin unassisted), strategically using them can help you keep your checked bags under the weight limit.
-
Carry-on dimensions: Up to 24" (L) x 16" (W) x 10" (H), including wheels and handles.
-
Personal item dimensions: Must fit under the seat in front of you, typically around 18.5" (L) x 13.5" (W) x 8.5" (H). Examples include purses, briefcases, laptop bags, or small backpacks.
Pro-Tip: Heavy items like books, electronics, or shoes can be moved from your checked bag to your carry-on or personal item if they're pushing your checked bag over the limit.
5.4 Pack Smart and Efficiently
-
Roll your clothes: This can save space and sometimes even prevent wrinkles.
-
Utilize packing cubes: These can help compress your clothes and keep your suitcase organized, making it easier to see if you have room for more.
-
Wear your heaviest items: If you're traveling with bulky shoes or a heavy coat, consider wearing them on the plane rather than packing them.
5.5 Know Your Fare Type and Rapid Rewards Status
As discussed, different fare types and Rapid Rewards statuses come with different baggage allowances. Double-check your specific booking details or your Rapid Rewards account to confirm your included baggage before you pack.
Step 6: Special Items - Beyond the Standard Suitcase
Southwest has specific policies for various special items, including sports equipment, musical instruments, and more. These items may be subject to standard checked bag fees if they fit within the weight and size limits, or they may incur additional charges if they exceed those limits.
Tip: Pause whenever something stands out.
6.1 Sports Equipment
Many common sports items, such as golf clubs, skis, or snowboards, can be checked as part of your standard baggage allowance if they meet the weight and size requirements. However, certain larger or heavier items may be subject to additional fees or may need to be shipped as cargo. Always check Southwest's specific policy for your particular sports equipment.
6.2 Musical Instruments
Musical instruments can often be carried on if they fit in the overhead bin or under the seat. Larger instruments may need to be checked, and if they exceed standard baggage limits, fees will apply. For very large instruments, purchasing an extra seat might be an option.
Step 7: When in Doubt, Call Southwest!
The information provided here is based on Southwest's general policies as of the current date. However, policies can change, and specific situations might have unique considerations. If you have any doubts or your luggage is particularly unusual, the best course of action is always to contact Southwest Airlines directly or consult their official website. Their customer service agents can provide the most accurate and up-to-date information for your specific travel plans.
