For decades, Southwest Airlines stood out from the crowd with its famous "Bags Fly Free" policy, a huge perk that endeared them to many travelers. However, as of May 28, 2025, that era has largely come to an end for most passengers. If you're planning to fly Southwest, understanding their new baggage policy is crucial to avoid unexpected costs. This comprehensive guide will walk you through everything you need to know about Southwest Airlines baggage fees, step by step.
Navigating the New Baggage Landscape: How Much Does it Cost Per Bag on Southwest Airlines?
Are you ready to dive into the specifics of Southwest's updated baggage policy? Let's get started!
Step 1: Understand the Core Change
First and foremost, let's address the elephant in the room. The "Bags Fly Free" policy is no longer universal. For flights booked or voluntarily changed on or after May 28, 2025, the majority of travelers will now incur fees for checked luggage. This change brings Southwest more in line with other major U.S. airlines.
The New Standard:
First Checked Bag: $35
Second Checked Bag: $45
These fees apply to most fare types, including Basic, Wanna Get Away Plus®, and Anytime fares.
Step 2: Identify if You're Exempt from the New Fees
While the "Bags Fly Free" policy is largely gone, there are still some fortunate travelers who will continue to enjoy free checked bags. It's essential to determine if you fall into one of these categories:
Sub-heading: Business Select® Passengers
If you've booked a Business Select® fare, you're in luck! You will still receive two free checked bags. This top-tier fare continues to offer this significant benefit.
Sub-heading: Rapid Rewards A-List Preferred Members
For the loyal flyers, Rapid Rewards A-List Preferred members are also eligible for two free checked bags. This is a fantastic perk for those who frequently fly with Southwest and have achieved this elite status.
Sub-heading: Rapid Rewards A-List Members
Rapid Rewards A-List members (the tier below A-List Preferred) will receive one free checked bag. While not two, it's still a valuable saving for frequent travelers.
Sub-heading: Rapid Rewards Credit Cardmembers
If you are a Southwest Rapid Rewards Credit Cardmember, you will typically receive a credit for your first checked bag. This is a great benefit for cardholders and can significantly offset your travel costs. Always check the specific terms and benefits of your particular Southwest credit card, as offers can vary.
Sub-heading: Active-Duty Military Personnel
Southwest Airlines offers a special exemption for active-duty military personnel with a current, valid military ID. They 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). This is a generous policy in appreciation of military service.
Step 3: Understand Standard Baggage Size and Weight Limits
Even if your bags are free or you're paying the standard fees, they must adhere to Southwest's size and weight limits. Failure to do so will result in additional charges.
Sub-heading: Checked Bag Dimensions
Each checked bag must not exceed 62 inches (length + width + height) in total linear dimensions. This includes wheels, handles, and any external attachments.
Sub-heading: Checked Bag Weight
Each checked bag must not weigh more than 50 pounds (22.7 kg).
Step 4: Account for Overweight and Oversized Baggage Fees
If your bags exceed the standard limits, be prepared to pay extra. These fees can quickly add up, so it's always best to pack smartly and weigh your bags before heading to the airport.
Overweight Baggage:
Bags weighing between 51 and 100 pounds (23.1 kg - 45.3 kg) will incur a fee of $100 per bag.
Bags exceeding 100 pounds are generally not accepted as checked baggage and may need to be shipped via Southwest Cargo if the Customer is a Known Shipper.
Oversized Baggage:
Bags measuring over 62 inches but not more than 80 inches (157.5 cm - 203 cm) in total linear dimensions will incur a fee of $100 per bag.
Bags exceeding 80 inches are generally not accepted as checked baggage and may need to be shipped via Southwest Cargo.
Important Note: If a bag is both overweight and oversized, you will be charged only one $100 fee, not a combination of both.
Step 5: Consider Additional Bags (Third Bag and Beyond)
What if you need to check more than two bags? Southwest does allow for additional checked bags, but the fees increase.
Third Checked Bag and Beyond:
For the third checked bag and any subsequent bags, the fee is $150 per bag.
Remember, standard size and weight limits still apply to these additional bags. If they are overweight or oversized, the respective fees ($100) will be added on top of the $150.
Step 6: Understand Carry-On and Personal Item Policies
While the focus here is on checked bags, it's worth noting Southwest's carry-on policy, as it remains a free option for all passengers. This can be a great way to avoid checked bag fees if you pack light.
Sub-heading: Carry-On Bag
You are allowed one carry-on bag per passenger.
Size Limit: Maximum dimensions are 24" (L) x 16" (W) x 10" (H). This includes wheels and handles.
It must fit in the overhead bin.
There is no weight restriction for carry-on bags, but you must be able to lift it into the overhead compartment unassisted.
Sub-heading: Personal Item
You are also allowed one personal item per passenger, in addition to your carry-on.
Size Limit: Examples include a purse, briefcase, laptop bag, or small backpack. It must fit under the seat in front of you.
Typically, personal items should not exceed 16.25” (L) x 13.5” (W) x 8” (H).
There is no weight restriction for personal items.
Step 7: Special Items and Sporting Equipment
Southwest has specific policies for various special items and sporting equipment. Many can be checked as part of your standard baggage allowance (if they meet the size/weight limits), but some may incur additional fees or have specific packing requirements.
Examples of Items that May Count as a Standard Bag (if within limits): Golf bags (excess size charges waived, but excess weight may apply), skis/snowboard equipment (can be split into two bags but count as one item if within limits).
Items that May Incur Additional Fees: Bicycles (may have specific boxing requirements and often incur a fee), surfboards, etc. Always check Southwest's official website for the most up-to-date and detailed information on special items.
Step 8: Consider Payment Options
Southwest does not allow you to prepay for checked baggage online or through their app. Baggage fees are typically paid at the airport:
At the check-in counter when you drop off your bags.
At a self-service kiosk.
Step 9: Maximize Your Savings: Tips and Tricks
Pack Light: This is the most obvious and effective way to save money. Can you fit everything into a carry-on and personal item?
Join Rapid Rewards: Even if you don't fly frequently enough for A-List status, collecting Rapid Rewards points is always a good idea.
Get a Southwest Rapid Rewards Credit Card: The free checked bag benefit alone can easily offset the annual fee for many of these cards.
Consider Business Select Fares: If you're traveling for business and your company covers the cost, or if the added benefits (like priority boarding and free drinks) justify the higher price, the two free checked bags are a bonus.
Consolidate Bags: If you're traveling with family or friends, try to consolidate your belongings into fewer bags to avoid additional bag fees for everyone.
Weigh Your Bags at Home: A simple luggage scale can save you significant money and stress at the airport.
Understand Your Fare Type: Before you book, review the fare details to see what baggage allowance, if any, is included.
