Let's dive in and break down everything you need to know about Southwest Airlines baggage costs for 2025, with a clear, step-by-step guide to help you avoid any unwelcome surprises.

Step 1: Understand the "New Normal" for Southwest Baggage
First things first, let's address the elephant in the room: Southwest's iconic "Bags Fly Free" policy is no longer universal for new bookings. As of May 28, 2025, Southwest began implementing new baggage fees for most passengers. This is a major shift, aligning them more closely with other major US airlines.
Why the change? Southwest has stated this move is part of a broader strategy to enhance profitability and offer more choices to customers. While it might be a departure from what many loyal Southwest flyers are used to, understanding these changes is the first and most important step in managing your travel budget.
Sub-heading: Who is Affected by the New Policy?
Most Travelers: If you booked or voluntarily changed your flight on or after May 28, 2025, and you have a Basic, Wanna Get Away Plus®, or Anytime fare, you will now be subject to checked baggage fees.
Bookings Before May 28, 2025: If your reservation was booked and ticketed (or voluntarily changed) on or before May 27, 2025, your original baggage policy (likely two free checked bags) still applies, regardless of your travel date. This is a key point to remember!
Step 2: Deconstructing the Standard Checked Bag Fees
Now, let's talk numbers. For most travelers falling under the new policy, here's what you can expect for standard checked bags:
First Checked Bag: $35 USD
Second Checked Bag: $45 USD
These fees are per bag, per one-way trip. So, for a round-trip journey with two checked bags, you'd be looking at a total of $160 ($35 + $45 for the outbound, and $35 + $45 for the return).
Sub-heading: What are the Size and Weight Limits for Standard Bags?
It's not just about the cost; your bags also need to adhere to specific dimensions and weight limits to be considered "standard":
Maximum Weight: Each checked bag must not exceed 50 pounds (23 kg).
Maximum Size (Linear Dimensions): The sum of the length + width + height of your bag must not exceed 62 inches (158 cm). This includes handles and wheels.
Pro Tip: Always measure and weigh your bags before heading to the airport! A simple bathroom scale and a measuring tape can save you a lot of hassle and extra fees.
QuickTip: Don’t just consume — reflect.
Step 3: Unlocking Free Bags: Exceptions to the Rule
While the "Bags Fly Free" policy is largely gone, there are still ways to get complimentary checked bags on Southwest! These exceptions are crucial for frequent flyers or those who choose specific fare types.
Sub-heading: Business Select® Fare Holders
If you purchase a Business Select® fare, you are entitled to two free checked bags. This is Southwest's top-tier fare and comes with other perks like priority boarding.
Sub-heading: Rapid Rewards® A-List Preferred Members
Passengers who have achieved Rapid Rewards® A-List Preferred status will continue to receive two free checked bags. This is a loyalty perk for frequent Southwest flyers.
Sub-heading: Rapid Rewards® A-List Members
A-List Members (the lower tier of Southwest's loyalty program) are now eligible for one free checked bag.
Sub-heading: Rapid Rewards® Credit Cardmembers
If you are the primary holder of a Southwest co-branded credit card, you are eligible for one free checked bag. This benefit also extends to up to eight additional passengers traveling on the same reservation, provided the primary cardmember is on the reservation and their Rapid Rewards account number is included.
Important Note: Always verify your specific fare rules and Rapid Rewards status benefits as they can sometimes be subject to change.
Step 4: Navigating Overweight, Oversized, and Excess Baggage Fees
Sometimes, a standard bag just isn't enough. Whether you're packing for an extended trip or bringing back souvenirs, be aware of these additional charges:
Sub-heading: Overweight Baggage Fees
If your checked bag exceeds the 50-pound (23 kg) weight limit, but is still within the 100-pound limit, you will incur an overweight baggage fee:
51-70 pounds (24-32 kg): $100 USD per bag
71-100 pounds (33-45 kg): $200 USD per bag
Bags weighing over 100 pounds will generally not be accepted as checked baggage and may need to be shipped via Southwest Cargo if you are a "Known Shipper."
Tip: Use this post as a starting point for exploration.
Sub-heading: Oversized Baggage Fees
If your checked bag exceeds the 62 linear inches (158 cm) size limit, but is still within the 80 linear inches limit, you will incur an oversized baggage fee:
63-80 inches (160-203 cm): $200 USD per bag
Bags exceeding 80 linear inches will not be accepted as checked baggage.
Sub-heading: Excess Baggage Fees (Third Bag and Beyond)
If you need to check a third bag or more, you will be charged an excess baggage fee in addition to any standard, overweight, or oversized fees that apply to those specific bags:
3rd+ Checked Bag: $150 USD per bag
Maximum Limit: Southwest generally limits customers to checking 20 pieces of baggage per flight.
Note on Combined Fees: If a bag is both oversized and overweight (but does not exceed 100 lbs and 80 inches), typically only the higher of the two fees applies. For example, if a bag is 55 lbs and 65 inches, it would incur the $200 oversized fee, not both the overweight and oversized fees. Always confirm with Southwest if you have a bag that falls into both categories.
Step 5: Understanding Carry-On and Personal Item Policies
Even with checked bag fees, carry-on bags and personal items remain free. This is often where travelers try to optimize their packing!
Sub-heading: Carry-On Bag Allowance
 |
You are permitted one carry-on bag per passenger, free of charge.
Maximum Dimensions: Your carry-on bag must not exceed 24” (L) x 16” (W) x 10” (H). This includes wheels and handles.
Weight Limit: There is no specified weight restriction for carry-on items, but you must be able to lift it into and out of the overhead bin yourself.
Stowage: Carry-on bags are designed to fit in the overhead compartments.
Sub-heading: Personal Item Allowance
In addition to your carry-on bag, you can bring one smaller personal item, free of charge.
Examples: This typically includes items like a purse, briefcase, laptop computer case, small backpack, or camera bag.
Maximum Dimensions: Your personal item should be able to fit under the seat in front of you. While specific dimensions aren't as strictly enforced as carry-ons, a general guideline is around 16.25” x 13.5” x 8”.
Stowage: Personal items must fit under the seat in front of you.
Important Considerations:
Items like jackets, umbrellas, assistive devices (wheelchairs, crutches), and food for consumption during the flight (in disposable packaging) typically do not count towards your carry-on or personal item limit.
If you're traveling with a pet, the pet carrier will count as either your personal item or your carry-on. A separate fee applies for pets traveling in the cabin.
Tip: Don’t rush — enjoy the read.
Step 6: Special Baggage and Sports Equipment
Planning to bring your skis, golf clubs, or a musical instrument? Southwest has specific policies and potential fees for these items.
Many types of sports equipment (e.g., golf clubs, skis, snowboards, fishing equipment) can be checked as one piece of your standard checked baggage allowance, provided they meet the weight and size limits.
If the sports equipment is oversized or overweight, the corresponding fees will apply. Some larger items, like bicycles or surfboards (over 62 inches), may incur specific higher fees or even require shipping as cargo.
Musical Instruments: Small instruments that fit within carry-on dimensions can be brought on board. Larger instruments may need to be checked and are subject to checked baggage rules and potential oversized/overweight fees. You may also purchase a separate seat for a large, fragile instrument if you wish to keep it in the cabin, provided it fits in the seat.
Always check Southwest's "Optional Travel Charges" page or contact their customer service directly for specific details on your particular special item. Policies can vary for certain items or destinations.
Step 7: Tips for Saving on Southwest Baggage Fees
Now that you know the costs, let's explore ways to minimize them!
Pack Light and Smart: This is the most obvious but often overlooked tip. Do you really need that third pair of shoes? Consider bringing travel-sized toiletries.
Utilize Your Carry-On and Personal Item: Maximize the space in your free carry-on and personal item. A good travel backpack can hold a surprising amount.
Consider a Southwest Rapid Rewards Credit Card: If you fly Southwest frequently, the free checked bag perk from their co-branded credit card can quickly offset the annual fee.
Achieve A-List or A-List Preferred Status: For very frequent flyers, reaching elite status is the ultimate way to enjoy complimentary bags and other benefits.
Ship Your Luggage: For exceptionally large or numerous items, consider using a luggage shipping service. Sometimes, this can be more cost-effective than airline excess baggage fees.
Pool Baggage Allowance: If you're traveling with family or friends on the same reservation, remember that some benefits (like the Rapid Rewards Credit Card free bag) might extend to others on your booking. Coordinate your packing!
Understand Your Fare Type: Double-check the baggage allowance tied to the specific fare you've purchased. Basic fares will have the strictest baggage rules.
By understanding these policies and planning ahead, you can confidently navigate Southwest Airlines' baggage fees and ensure a smoother, more budget-friendly travel experience in 2025!
