Traveling with Southwest Airlines used to be synonymous with "Bags Fly Free," a unique perk that set them apart from other major U.S. carriers. However, as of May 28, 2025, Southwest has implemented significant changes to its baggage policy, aligning itself more closely with industry standards. Don't worry, though, there are still ways to understand and optimize your baggage allowance!
Let's dive into a comprehensive, step-by-step guide on how many bags you can carry on a plane with Southwest Airlines, including their updated policies for 2025.
Step 1: Let's Talk Bags! Are You Ready to Unpack Southwest's New Rules?
First things first, let's get you in the loop. Southwest Airlines, while still offering some fantastic benefits, has adjusted its baggage policy. The era of two free checked bags for all passengers has largely concluded. This means that for many travelers, checked bags will now incur a fee. But don't fret! Understanding the new rules is your key to a smooth and budget-friendly journey.
This guide will break down everything you need to know, from carry-ons to checked bags, and even special items. So, grab a cup of coffee, and let's make sure you're ready to fly without any baggage surprises!

Step 2: Understanding Your Carry-On Allowance (The Essentials!)
When it comes to carry-on bags, Southwest Airlines maintains a fairly consistent and generous policy. You're typically allowed two types of items to bring into the cabin:
2.1: Your Primary Carry-On Bag
This is the bag that usually goes in the overhead bin.
-
Dimensions: Your carry-on bag must not exceed 24 x 16 x 10 inches (approx. 61 x 40 x 25 cm), including handles and wheels.
-
Weight Limit: Southwest does not specify a weight limit for carry-on items, but you must be able to lift it into and out of the overhead bin yourself.
-
What it is: Think small suitcases, duffel bags, or larger backpacks that fit within these dimensions.
2.2: Your Personal Item
This smaller item is designed to fit under the seat in front of you.
QuickTip: Scan the start and end of paragraphs.
-
Dimensions: Your personal item should not exceed 18.5 x 13.5 x 8.5 inches (approx. 47 x 34 x 22 cm).
-
Weight Limit: Similar to carry-ons, there is no specified weight limit for personal items.
-
What it is: This typically includes items like a purse, briefcase, laptop bag, small backpack, or camera bag. It's crucial that it fits snugly under the seat.
2.3: Items That Don't Count Towards Your Limit
Good news! Several items can be brought on board in addition to your carry-on and personal item. These include:
-
A child restraint device (for a ticketed child with a reserved seat, or if complimentary space is available)
-
Assistive/mobility devices for individuals with disabilities (no limit on the number of these devices)
-
Outer garments or other wearable articles of clothing (like a coat or wrap)
-
Food for consumption during the flight (in disposable packaging)
-
Walking canes or umbrellas
-
Medications (e.g., insulin kits, EpiPens, and other prescription or over-the-counter medications that have been screened at security). Note: Liquid medications usually follow TSA's 3-1-1 rule unless accompanied by a doctor's note.
Step 3: Navigating Checked Baggage (The New Landscape for 2025)
This is where the most significant changes for Southwest Airlines come into play as of May 28, 2025.
3.1: The Standard Checked Baggage Allowance
For most passengers, the "Bags Fly Free" policy is no longer the default.
-
First Checked Bag: Expect a fee of approximately $35.
-
Second Checked Bag: The fee for a second checked bag will be around $45.
-
Maximum Dimensions (per bag): Each checked bag must not exceed 62 linear inches (length + width + height). This includes handles and wheels.
-
Maximum Weight (per bag): Each checked bag must not exceed 50 pounds (23 kg).
3.2: Who Still Gets Free Checked Bags? (The Exceptions!)
While the policy has changed for many, some travelers can still enjoy complimentary checked baggage:
-
Business Select Fares: Passengers who book a Business Select fare will continue to receive two free checked bags.
-
Rapid Rewards A-List Preferred Members: These elite loyalty members also get two free checked bags.
-
Rapid Rewards A-List Members: If you're an A-List member, you'll be entitled to one free checked bag.
-
Southwest Credit Card Holders: Many Southwest co-branded credit cards offer one free checked bag as a benefit. Always check your specific card's terms and conditions.
-
Active-Duty Military Personnel: With a current, valid military ID, active-duty military passengers are exempt from the two-piece baggage limit and will not be subject to excess, oversize, or overweight baggage charges, provided that none of the pieces of baggage exceeds 100 pounds in weight and 80 inches in siz
3.3: Fees for Additional, Overweight, or Oversized Bags
QuickTip: Reading twice makes retention stronger.
If your bags exceed the standard limits, or if you need to check more than your allowance, be prepared for additional fees:
-
Third (or more) Checked Bag: For a third checked bag and beyond, the fee is generally around $150 per bag.
-
Overweight Baggage:
-
51 - 70 lbs (24 - 32 kg): Approximately $100 per bag.
-
71 - 100 lbs (32 - 45 kg): Approximately $200 per bag.
-
Bags exceeding 100 pounds will not be accepted as checked baggage and must be shipped as air cargo.
-
-
Oversized Baggage:
-
63 - 80 linear inches (160 - 203 cm): Approximately $200 per bag.
-
Bags greater than 80 inches (for general baggage) or 115 linear inches (for certain sports equipment) will not be accepted as checked baggage and must be shipped as air cargo.
-
Important Note: If a bag is both oversized and overweight, only one applicable fee will be charged, provided it doesn't exceed 100 lbs.
-
Step 4: Special Baggage & Sports Equipment
Southwest Airlines has specific guidelines for various special items and sports equipment. Many can be substituted for a piece of checked baggage, but size and weight restrictions still apply, and additional fees may be incurred.
 |
4.1: Musical Instruments
-
Carry-on: If your instrument (including case) fits within the standard carry-on dimensions (24 x 16 x 10 inches), you may bring it as your carry-on, space permitting. Even if slightly larger, it might be allowed in the overhead bin or under a seat if space is available.
-
Purchasing a Seat: For larger instruments that don't fit in the overhead bin or under a seat, you can purchase an additional seat for them. The instrument must fit in the seat, be secured with a seatbelt, and not block aircraft signage. It must be placed in the first row, closer to the window.
-
Checked Baggage: Instruments can be checked as baggage. Standard checked baggage fees and dimensions (50 lbs, 62 linear inches) apply.
-
Oversize/Overweight Fees: Instruments between 62 and 150 linear inches (including case) or weighing between 51 and 165 pounds (including case) will incur the standard oversize/overweight fees.
-
Southwest will not accept musical instruments exceeding 150 linear inches or 165 pounds.
-
Instruments in soft-sided cases or inadequate packaging may be accepted with limited liability for damage.
-
4.2: Sports Equipment
Southwest generally accepts most common sports equipment as checked baggage, subject to standard baggage policies. However, some items have specific rules and potential fees:
-
General Rule: If your sports equipment (e.g., golf clubs, skis, snowboards) falls within the 50 lbs and 62 linear inches limits, it will count as one of your checked bags. Applicable fees for checked bags will apply based on your fare type or status.
-
Oversized/Overweight Sports Equipment:
-
Many sports items can be oversized (e.g., up to 115 linear inches for some items like skis/snowboards) without an additional "oversized" fee, but they will still be subject to standard checked bag fees if applicable.
-
Overweight fees will apply if the equipment exceeds 50 lbs.
-
Specific Items and Considerations:
-
Golf Clubs: One golf bag containing clubs, balls, and shoes is generally accepted as one checked bag.
-
Skis/Snowboards: A ski bag and boot bag (containing skis/snowboard and boots) count as one item.
-
Bicycles: Must be packed in a bicycle box or bag. Specific restrictions and fees may apply.
-
Surfboards: Accepted for a fee (typically $75) on most flights, but may count as a free checked bag on Hawaiian inter-island flights (if within weight limits). Keels and fins must be removed.
-
-
Always check Southwest's "Optional Travel Charges" page for the most up-to-date and detailed information on specific sports equipment.
-
Step 5: Tips for a Smooth Baggage Experience
-
Measure and Weigh Before You Go: This is crucial! Invest in a luggage scale and a measuring tape. Avoid surprises and potential fees at the airport.
-
Check Your Fare Type and Status: Your ticket class (e.g., Business Select, Wanna Get Away Plus, Basic) and Rapid Rewards status (A-List, A-List Preferred) directly impact your checked baggage allowance.
-
Consider a Southwest Credit Card: If you fly Southwest frequently, a co-branded credit card could save you money on checked bag fees.
-
Pack Smartly: Maximize your carry-on space by rolling clothes, using packing cubes, and wearing your heaviest items.
-
Label Your Bags: Always put your contact information (name, phone number, email) both inside and outside your checked bags.
-
Arrive Early: Especially if you're checking bags, allow ample time at the airport. Baggage checked less than 45 minutes before departure (or 60-75 minutes for international flights) is considered "Late Check" and may not make your flight.
-
Keep Valuables in Your Carry-On: Always keep important documents, medication, electronics, and valuables with you in your carry-on bag.
-
Review Southwest's Official Website: Policies can change, so always refer to the official Southwest Airlines website or contact their customer service for the absolute latest information before your trip.
