Southwest Airlines has always been known for simplicity, transparency, and customer-friendly perks. For years, one of the biggest reasons travelers chose Southwest was its famous promise: two checked bags fly free. However, 2025 brought one of the most significant updates in the airline’s history — a new baggage fee structure.
If you're traveling with Southwest soon, here’s a clear and easy-to-understand breakdown of the updated baggage policy and what it means for your next trip.
What’s New in Southwest’s Baggage Policy?
Southwest no longer automatically includes two free checked bags for all passengers. This long-standing Southwest Airlines Baggage Policy changed in 2025, bringing the airline in line with most major carriers.
Standard Checked Bag Fees
First bag: $35
Second bag: $45
These fees now apply to the majority of travelers and are charged on a per-person, per-direction basis.
Who Still Enjoys Free Checked Bags?
While the universal free-bag policy has ended, Southwest still offers generous baggage benefits to certain customers.
Two Free Checked Bags
Business Select passengers
A-List Preferred elite members
One Free Checked Bag
A-List members
Travelers with Southwest-branded credit cards
Select bundled or promotional fare categories
If you fall into one of these groups, your benefits remain in place — and they can save you a significant amount.
Carry-On Policies Remain the Same
Even with the changes to checked bags, Southwest still offers a straightforward and generous carry-on allowance.
You can bring:
1 carry-on bag for the overhead bin
1 personal item that fits under the seat
Carry-on Bag Size Limit
24" x 16" x 10" (including handles and wheels)
Southwest does not set an official weight limit for carry-on bags, but it must be light enough for you to lift it safely into the overhead compartment.
Checked Bag Size Weight Rules
To avoid additional fees, make sure your checked bags meet Southwest’s standard limitations:
Maximum weight: 50 lbs
Maximum size: 62 linear inches (total length + width + height)
Extra Fees Apply For:
Bags weighing 51–70 lbs
Bags weighing 71–100 lbs
Oversized bags exceeding 62 inches
Third or more checked bags
These extra charges can be significant, so measuring and weighing your luggage at home is highly recommended.
Why Southwest Updated the Policy
Airline industry costs have risen across the board, from fuel to operations. Southwest, which historically avoided baggage fees, updated its policy in response to financial pressures and industry standards. The updated structure helps the airline maintain its competitive fares while still offering valuable perks to its loyal customer base.
Tips to Avoid Extra Costs
Here are some practical ways to keep your travel budget on track:
1. Check Your Loyalty Status
Even occasional travelers may qualify for A-List status or credit card perks.
2. Use Lightweight Luggage
This helps prevent accidental overweight fees — especially on longer trips.
3. Share Space
Families or groups can often combine belongings into fewer bags.
4. Plan to Carry On
If you really want to avoid baggage fees, consider traveling with just a carry-on and personal item.
5. Check Your Ticket Date
If you booked your trip before Southwest introduced the new fees, you may still qualify for the original free-bag policy.
The Bottom Line
Southwest Airlines’ 2025 baggage policy update marks a major shift for the brand, but it doesn’t eliminate all the value the airline is known for. Many travelers still qualify for free bags, and Southwest continues to offer flexible booking, no change fees, and an easy carry-on policy.
Understanding these new rules will help you plan better, pack smarter, and avoid unnecessary charges. Whether you travel light or bring everything with you, being informed ensures a smoother, stress-free journey.
