Traveling with Southwest Airlines used to be synonymous with "Bags Fly Free," a beloved perk that set them apart. However, as of May 28, 2025, Southwest has implemented significant changes to its baggage policy, meaning most travelers will now incur fees for checked luggage. This comprehensive guide will walk you through everything you need to know about Southwest's new checked baggage charges.
Are you ready to unpack the new Southwest Airlines baggage policy with us? Let's dive in!
Step 1: Understand the Big Shift – "Bags Fly Free" No More (For Most!)
For years, Southwest Airlines was the outlier, offering two free checked bags to every passenger, regardless of fare class. This was a major selling point and a key differentiator from other airlines. However, the landscape has changed. Beginning May 28, 2025, Southwest began charging for checked bags on certain fare types. This move aligns them more closely with the industry standard, and it's crucial for travelers to understand these new rules to avoid unexpected costs at the airport.
Step 2: Determine Your Fare Type and Its Baggage Allowance
The new baggage policy is largely dependent on the type of fare you've purchased. Not all fares are created equal when it comes to checked baggage.
Sub-heading 2.1: Who Still Gets Free Checked Bags?
While the general policy has changed, some passengers can still enjoy the benefit of free checked bags:
Business Select® Fares: If you've booked a Business Select fare, you will continue to receive two free checked bags. This is their premium fare, offering more flexibility and perks, including the baggage allowance.
Rapid Rewards® A-List Preferred Members: These highly valued loyalty members still get their first and second checked bags for free.
Rapid Rewards® A-List Members: Members with A-List status are entitled to their first checked bag for free.
Rapid Rewards® Credit Cardmembers: If you're a primary Rapid Rewards Credit Cardmember, you'll receive your first standard checked bag for free. This benefit also extends to up to eight additional passengers on the same reservation, provided your Rapid Rewards account number is included.
Hawaii Residents (Inter-Island Travel): Customers residing in Hawaii and traveling between the islands will continue to receive two free checked bags.
Active-Duty Military Personnel: Members of the military on active duty with a valid military ID are exempt from the two-piece baggage limit and will not be subject to excess, oversize, or overweight baggage charges, provided each piece of baggage does not exceed 100 pounds in weight and 80 inches in size (L+W+H).
Sub-heading 2.2: Who Will Pay for Checked Bags and How Much?
For reservations booked and ticketed, or voluntarily changed, on or after May 28, 2025, the following fare types will incur checked baggage fees:
Basic Fares: This is Southwest's new lowest price point and comes with less flexibility and checked bag fees.
Wanna Get Away Plus® Fares: Checked bag fees will apply.
Anytime Fares: Checked bag fees will apply.
So, if you fall into one of these categories, here's what you can expect to pay:
First Checked Bag: Approximately $35 USD
Second Checked Bag: Approximately $45 USD
It's important to note that these fees are per bag, per direction of travel. So, a round trip with two checked bags on a Basic fare could cost you an additional $160 ($35 + $45 outbound, and $35 + $45 inbound).
Step 3: Understand Standard Baggage Dimensions and Weight Limits
Even if your bags are free based on your fare or status, they still need to adhere to Southwest's standard size and weight limits. Exceeding these limits will result in additional charges.
Sub-heading 3.1: Standard Checked Bag Limits
For all checked bags, regardless of whether they are free or paid:
Maximum Weight: 50 pounds (23 kg) per bag.
Maximum Linear Dimensions: 62 inches (157 cm) (length + width + height) per bag.
Sub-heading 3.2: Carry-on and Personal Item Allowance
These rules remain largely unchanged and are distinct from checked baggage:
Carry-on Bag: You are generally allowed one carry-on bag that must fit in the overhead bin. The maximum dimensions are typically 24 x 16 x 10 inches (approx. 61 x 40 x 25 cm), including handles and wheels. There is no specified weight limit for carry-on items, but you must be able to lift it into the overhead bin unassisted.
Personal Item: In addition to your carry-on, you can bring one small personal item that must fit under the seat in front of you. Examples include a purse, briefcase, laptop bag, or small backpack. The approximate maximum dimensions are 18.5 x 8.5 x 13.5 inches (approx. 47 x 21.5 x 34 cm).
Note: If you are traveling with a pet, the pet carrier counts as either your carry-on or personal item.
Step 4: Prepare for Overweight and Oversized Baggage Fees
If your checked bags exceed the standard weight or size limits, be prepared for additional fees. These fees are in addition to the standard checked bag fees (if applicable to your fare).
Sub-heading 4.1: Overweight Baggage Fees
For bags weighing between 51 and 100 pounds (23-45 kg): Approximately $100 USD per bag.
Bags weighing over 100 pounds (45 kg) will generally not be accepted as checked baggage and may need to be shipped via Southwest Cargo if you are a Known Shipper.
Sub-heading 4.2: Oversized Baggage Fees
For bags with linear dimensions between 63 and 80 inches (158-203 cm): Approximately $125 USD per bag.
Bags exceeding 80 linear inches (203 cm) will generally not be accepted as checked baggage.
Step 5: Consider Special Items and Sports Equipment
Southwest has specific policies for various special items and sports equipment. While some may fall under your standard baggage allowance if they meet size and weight limits, others may incur additional fees or have specific handling requirements. Always check Southwest's official website for the most up-to-date information on specific items you plan to travel with.
Step 6: How to Pay for Checked Baggage
Southwest Airlines typically collects checked baggage fees at the airport. You cannot generally prepay for checked baggage online when booking. You will pay at the ticket counter or at the self-tagging kiosks.
Step 7: A Few Extra Tips to Save Money and Hassle
Measure and Weigh Before You Go: Invest in a luggage scale and measure your bags to avoid surprises at the airport. It's much cheaper to redistribute weight or leave items behind at home than to pay overweight fees.
Pack Smart: If you're traveling light, see if you can fit everything into a carry-on and personal item to avoid checked bag fees entirely.
Consider Southwest Credit Cards: If you fly Southwest frequently, a Rapid Rewards Credit Card could easily save you money on baggage fees, offsetting the annual fee.
Elite Status Benefits: If you're a frequent flyer, aiming for A-List or A-List Preferred status can bring significant baggage benefits, among other perks.
Check for Embargoes: For international travel, Southwest may have baggage embargoes in place for certain countries or during peak seasons, which can restrict oversized, overweight, or extra checked bags. Always verify this for your specific itinerary.
Military Personnel Perks: If you are active-duty military, ensure you have your valid military ID to avail yourself of the generous baggage allowance.

How to avoid Southwest checked baggage fees? The best ways to avoid Southwest checked baggage fees are to qualify for free bags through fare type (Business Select), Rapid Rewards A-List/A-List Preferred status, being a Rapid Rewards Credit Cardmember, being active-duty military, or by fitting all your belongings into your free carry-on and personal item.

How to travel with sports equipment on Southwest Airlines? Many common sports equipment items can be checked as part of your standard baggage allowance if they meet the weight and size limits. However, some larger or specialized items may incur additional fees or have specific packaging requirements. Always check Southwest's policy for the specific item (e.g., skis, golf clubs, bicycles).
