Traveling with Southwest Airlines used to be synonymous with "Bags Fly Free," a truly unique perk in the airline industry. However, as of May 28, 2025, that era has largely come to an end. Southwest has updated its baggage policy, bringing it more in line with other major carriers. So, if you're wondering "how much is a third bag on Southwest Airlines," you're asking a very relevant question in this new landscape!
This comprehensive guide will walk you through everything you need to know about Southwest's baggage fees, especially concerning that third bag, and provide tips to help you manage your travel budget.
Step 1: Let's Get Real About Your Packing Habits!
Before we dive into the nitty-gritty of fees, take a moment to honestly assess your packing style. Are you a minimalist, or do you believe in bringing everything just in case? If you're consistently traveling with more than two bags, Southwest's new policy will directly impact your wallet. Understanding your needs upfront will help you strategize and potentially save some cash. Seriously, have you ever considered if you truly need that third pair of shoes?

| How Much Is A Third Bag On Southwest Airlines |
Sub-heading: The "Old" vs. The "New" Southwest Baggage Policy
It's crucial to understand the shift. Previously, Southwest allowed two free checked bags for all passengers, regardless of fare type. This was a significant differentiator. Now, for flights booked or voluntarily changed on or after May 28, 2025, standard baggage fees apply to most fare types.
Step 2: Understanding the Standard Checked Bag Fees
Before we get to the third bag, let's establish the baseline costs for your first and second checked bags. This will set the context for the additional fees.
Sub-heading: First and Second Bag Costs (for most fares)
For most Southwest Airlines fares (Basic, Wanna Get Away Plus®, and Anytime fares), the fees are as follows:
First Checked Bag: Approximately $35
Second Checked Bag: Approximately $45
These fees are per bag, each way. So, a round trip with two checked bags for a standard fare would set you back $35 (outbound) + $45 (outbound) + $35 (return) + $45 (return) = $160. It adds up quickly!
Step 3: The Cost of Your Third Bag on Southwest Airlines
Tip: Jot down one takeaway from this post.
Now for the main event! What's the damage for that third checked bag?
Third Checked Bag (and any additional bags beyond two): Approximately $150 per bag
This fee applies to each additional bag beyond your first two. So, if you check three bags, you'd pay $35 (first) + $45 (second) + $150 (third) = $230 for a one-way trip. If you check four bags, it would be $35 + $45 + $150 + $150 = $380 for a one-way trip.
Sub-heading: Important Considerations for All Checked Bags
Regardless of whether it's your first, second, or third bag, all checked bags must adhere to Southwest's standard size and weight limits to avoid additional charges.
Standard Size Limit: Up to 62 inches (length + width + height). This includes wheels and handles.
Standard Weight Limit: Up to 50 pounds (23 kg) each.
Step 4: Decoding Overweight and Oversized Bag Fees
Just because you pay for a third bag doesn't mean it's free from other charges! If your third bag (or any bag) exceeds the standard weight or size limits, additional fees will apply.
Sub-heading: Overweight Bag Charges
51 to 70 pounds: Approximately $100 + Standard Bag Fee (e.g., if your third bag is 60 lbs, you'd pay $150 + $100 = $250)
71 to 100 pounds: Approximately $200 + Standard Bag Fee (e.g., if your third bag is 80 lbs, you'd pay $150 + $200 = $350)
Bags exceeding 100 pounds will generally not be accepted as checked baggage and may need to be shipped as cargo.
Sub-heading: Oversized Bag Charges
Bags larger than 62 inches, up to 80 inches: Approximately $200 + Standard Bag Fee.
Bags exceeding 80 inches may also need to be shipped as cargo.
Sub-heading: When Both Apply (Oversized AND Overweight)
If a single bag is both oversized AND overweight, you'll generally be charged the higher of the two applicable fees, plus the standard bag fee. For example, if your third bag is 70 lbs and 70 inches, you'd pay $150 (third bag) + $200 (oversized) = $350. It's crucial to measure and weigh your bags before heading to the airport!
Tip: Read actively — ask yourself questions as you go.
Step 5: Exceptions to the Baggage Fee Rules
While the "Bags Fly Free" policy is mostly gone, there are still some scenarios where you might avoid or reduce baggage fees.
Sub-heading: How to Potentially Get Free Checked Bags
Business Select® Fares: Passengers traveling on a Business Select® fare still receive two free checked bags.
Rapid Rewards® A-List Preferred Members: These elite members receive their first and second checked bags free.
Rapid Rewards® A-List Members: A-List members receive their first checked bag free.
Southwest Rapid Rewards® Credit Cardmembers: Primary credit card members with their Rapid Rewards account number included in the reservation generally receive their first checked bag free.
Active Duty U.S. Military Personnel: Active duty military personnel traveling on active duty or permanent change of station orders are exempt from checked, overweight, and oversized bag fees, provided the bags do not exceed 100 pounds and 80 inches. This is a significant benefit!
Sub-heading: Special Items (Sports Equipment, etc.)
Southwest has specific policies for various types of sports equipment and other special items. While some items might have their oversized fees waived, standard checked bag fees and applicable overweight charges generally still apply. Always check Southwest's official website for the most up-to-date information on specific items like skis, golf clubs, musical instruments, etc.
Step 6: Paying for Your Bags and Other Logistics
Southwest does not allow you to prepay for luggage online. All baggage fees must be paid at the airport.
Sub-heading: Where to Pay
 |
Self-Tagging Kiosks (where available): Many airports offer self-tagging kiosks, allowing you to print your bag tags and then drop them off. You'll pay for any applicable fees at the kiosk.
Ticket Counter: You can always check your bags and pay any fees with a Southwest agent at the ticket counter.
Sub-heading: When to Check Your Bags
Southwest recommends checking bags at least 45 minutes prior to your scheduled departure for domestic flights and 60 minutes for international flights. Always arrive with plenty of time, especially if you anticipate paying for extra bags or dealing with potential issues.
QuickTip: Note key words you want to remember.
Step 7: Strategies to Avoid or Minimize Third Bag Fees
Since a third bag can be quite costly, here are some strategies to consider:
Pack Lighter: This might sound obvious, but it's the most effective way. Can you really live without that extra pair of shoes or that just-in-case outfit?
Ship Your Items: For truly bulky or numerous items, consider shipping them via a third-party service (like FedEx or UPS) or a luggage shipping service. This can sometimes be more cost-effective than airline fees, especially for multiple heavy bags.
Wear Your Heaviest Items: If you have heavy clothing items (like a thick coat or boots), wear them on the plane instead of packing them.
Maximize Your Carry-On and Personal Item: Southwest still allows one carry-on bag and one personal item for free. Make the most of this allowance! Ensure your carry-on meets the dimensions (10 x 16 x 24 inches) and your personal item fits under the seat (e.g., a backpack, laptop bag, large purse).
Consolidate with Travel Companions: If you're traveling with others, can you consolidate belongings into fewer bags? Just be mindful of individual bag weight limits.
Consider a Southwest Rapid Rewards Credit Card: If you frequently fly Southwest and check bags, the annual fee for a co-branded credit card might be offset by the free first checked bag benefit.
Attain A-List or A-List Preferred Status: For very frequent flyers, achieving elite status can provide valuable baggage benefits.
Step 8: Double-Checking Everything Before You Go
The last thing you want is a surprise at the airport.
Sub-heading: Official Sources are Your Best Friend
Always consult the official Southwest Airlines website for the most current and accurate baggage policy information. Policies can change, and online articles (even this one!) might not be immediately updated.
Use online baggage fee calculators if available on the Southwest site to estimate your costs.
Sub-heading: Measure and Weigh at Home
Invest in a luggage scale! It's a small investment that can save you significant money in overweight bag fees. Measure your bag's dimensions (length + width + height) to ensure it's within the limits.
