You've landed here because you're wondering about the cost of checking a bag on Southwest Airlines. For a long time, Southwest was synonymous with "Bags Fly Free," a truly unique selling proposition in the airline industry. However, as of May 28, 2025, that widely cherished policy has undergone a significant change. So, let's dive into everything you need to know, step-by-step, to understand the current costs and how to potentially minimize them!
Step 1: Are You Affected by the New Policy? Let's Find Out!
First things first, let's figure out if these new fees even apply to your travel plans. This is the crucial starting point, as not everyone will be subject to the new baggage charges.
When did you book your flight? The new policy applies to flights booked or voluntarily changed on or after May 28, 2025. If you booked your flight before this date, you might still be eligible for the previous "Bags Fly Free" policy, depending on your fare class at the time of booking. Always double-check your original booking confirmation!
What's your Rapid Rewards status or fare class? Southwest is maintaining some perks for its loyal customers and those who opt for higher-tier fares. This is where the "Bags Fly Free" policy still lives for some.
Business Select® Fare: If you booked a Business Select® fare, congratulations! You still get two free checked bags.
Rapid Rewards A-List Preferred Members: As an A-List Preferred member, you and up to eight additional passengers on the same reservation are entitled to two free checked bags.
Rapid Rewards A-List Members: If you're an A-List member, you get one free checked bag, and this benefit extends to up to eight additional passengers on the same reservation.
Rapid Rewards Credit Cardmembers: If you hold a Southwest co-branded credit card, you're eligible for one free checked bag for yourself and up to eight additional passengers on the same reservation.
Active Duty Military: Active duty military personnel with a valid military ID are exempt from checked bag fees, including overweight and oversized charges, as long as bags don't exceed 100 pounds and 80 inches.
If you don't fall into one of the above categories, then yes, the new checked bag fees will likely apply to you. Don't worry, we'll break down those costs next!

| How Much Does It Cost To Check A Bag On Southwest Airlines |
Step 2: Understanding the Standard Checked Bag Fees
For most travelers, the days of universally free checked bags on Southwest are over. Here's a breakdown of the standard fees you can expect for flights booked on or after May 28, 2025:
First Checked Bag: The cost for your first checked bag is $35.
Second Checked Bag: The cost for your second checked bag is $45.
These fees apply per bag, per one-way trip. So, for a round trip with two checked bags, you'd be looking at $35 (outbound) + $45 (outbound) + $35 (return) + $45 (return) = $160 in total.
QuickTip: Skim the intro, then dive deeper.
Important Note on Payment:
Southwest Airlines does not allow you to prepay for luggage online. All checked baggage fees must be paid at the airport, either at a self-tagging kiosk (where available) or with a Southwest agent at the check-in counter.
Step 3: Navigating Baggage Size and Weight Limits (and Associated Fees!)
Beyond the number of bags, the size and weight of your luggage are critical factors that can lead to additional charges. Failing to adhere to these limits can significantly increase your overall baggage cost.
Standard Limits for Checked Bags:
Before we talk about extra fees, let's understand the standard limits that allow you to pay just the $35 or $45 fee:
Weight: Each checked bag must weigh 50 pounds (23 kg) or less.
Size (Linear Dimensions): The total linear dimensions (length + width + height) of each checked bag must not exceed 62 inches (158 cm). This includes handles and wheels!
Tip: Scroll slowly when the content gets detailed.
Sub-heading: Overweight Bag Fees
If your bag exceeds the standard 50-pound weight limit, you're in for an extra charge.
51 to 70 pounds (24 to 32 kg): Bags in this weight range will incur a fee of $100 per bag. This is in addition to the standard $35 or $45 checked bag fee.
71 to 100 pounds (33 to 45 kg): For bags weighing between 71 and 100 pounds, the fee jumps to $200 per bag. Again, this is on top of the standard checked bag fee.
Bags exceeding 100 pounds (45 kg) will generally NOT be accepted as checked baggage and may need to be shipped as Air Cargo.
Sub-heading: Oversized Bag Fees
If your bag's total linear dimensions (length + width + height) exceed 62 inches, you'll also face an oversized fee.
63 to 80 inches (160 to 203 cm): Bags that are larger than 62 inches but do not exceed 80 inches will be charged $200 per bag. This is in addition to your standard checked bag fee.
Bags exceeding 80 inches (203 cm) will generally NOT be accepted as checked baggage.
Sub-heading: Combined Overweight and Oversized Fees
What happens if your bag is both overweight and oversized? Good news (sort of)! Southwest typically only applies one surcharge if your bag falls into both categories. For example, if your bag is 65 inches and weighs 55 pounds, you'd pay the $200 oversized fee (plus the standard checked bag fee), not $100 for overweight and $200 for oversized. However, always confirm with Southwest directly if you have an unusually sized or weighted item.
Tip: Read the whole thing before forming an opinion.
Step 4: Considering Additional Bags (Beyond Two)
While Southwest traditionally allowed two free bags, the new policy outlines fees for the first two. What if you need to check more than that?
Third and Subsequent Checked Bags: Any bag beyond your first two (i.e., your third, fourth, etc., up to a maximum of ten per passenger) will cost $150 per bag. This fee applies regardless of whether your first two bags were free due to your status/fare class or if you paid the standard $35/$45.

Step 5: Special Baggage and Sports Equipment
Traveling with golf clubs, skis, or a surfboard? Southwest has specific policies and fees for these items. Often, they count towards your checked baggage allowance (and associated fees), but may have special considerations for their dimensions.
General Rule: Many standard sports equipment items (e.g., golf bags, ski/snowboard equipment) may count as one checked bag. If they exceed standard weight or size limits, the respective overweight/oversized fees will apply.
Always check Southwest's official "Optional Travel Charges" page or contact them directly for specific details on your particular sports equipment, as rules can vary for different items. Some items might have waived oversized fees, but still incur overweight fees.
Step 6: Understanding Southwest's Carry-On Policy (Still Free!)
Tip: Watch for summary phrases — they give the gist.
While checked bag fees are a new reality for many, Southwest's carry-on policy remains a great way to avoid fees.
One Carry-On Bag: Each passenger is allowed one carry-on bag for free.
Maximum size: 24” (L) x 16” (W) x 10” (H) including handles and wheels.
No stated weight limit, but you must be able to lift it into the overhead bin unassisted.
One Personal Item: In addition to your carry-on, you can bring one personal item for free.
Examples: Purse, briefcase, laptop bag, small backpack.
Must fit under the seat in front of you.
No stated weight limit.
If you can pack light and fit everything into a carry-on and personal item, you can still fly Southwest without paying any baggage fees!
Step 7: Pro Tips for Saving on Baggage Fees
Now that you know the costs, here are some strategies to keep those dollars in your pocket:
Pack Light: This is the most obvious and effective strategy. Can you share a bag with a travel companion? Do you really need that third pair of shoes? Every ounce counts!
Utilize Your Carry-On and Personal Item: Maximize the space in your free carry-on and personal item. This is where strategic packing pays off.
Consider a Southwest Rapid Rewards Credit Card: If you fly Southwest frequently, the annual fee for a co-branded credit card might be offset by the free checked bag benefit it offers. Do the math!
Aim for Elite Status: For very frequent flyers, achieving A-List or A-List Preferred status can save you significant money on baggage fees over time.
Ship Your Luggage: For very heavy or numerous bags, consider using a luggage shipping service. Sometimes, the cost can be comparable to or even less than airline fees, and it offers the convenience of not dragging bags through the airport.
Dress in Layers: Wear your heaviest items (like coats or bulky shoes) on the plane to reduce bag weight.
