Oh, the dreaded baggage question! It's one of the most common stressors when planning a trip, especially with airlines constantly updating their policies. If you're flying Southwest, you might be used to their famously generous "Bags Fly Free" policy, but as of May 28, 2025, things have shifted. Let's break down exactly how much luggage is on Southwest Airlines, step-by-step, so you can pack smart and avoid any unwelcome surprises!
Navigating Southwest Airlines Luggage Policies: Your Step-by-Step Guide
Step 1: Let's get started! Have you ever arrived at the airport only to discover your bag is too big or too heavy? It's a frustrating experience, right? Well, with this guide, you'll be a Southwest baggage pro in no time! The first thing to understand is that Southwest's baggage policy underwent a significant change recently.

Step 2: Understanding the New Checked Baggage Fees
This is the biggest change, so pay close attention!
Sub-heading: The Standard Checked Bag Fees (for most travelers)
Effective May 28, 2025, for flights booked or voluntarily changed on or after that date, Southwest Airlines now charges for checked bags for most fare types.
First Checked Bag: Expect to pay $35.
Second Checked Bag: This will cost you $45.
These fees bring Southwest's baggage policy in line with many other major U.S. airlines. It's a significant shift from their previous model, so don't assume your bags will be free if you've flown Southwest before this date.
Sub-heading: Standard Dimensions and Weight Limits for Checked Bags
Even with the new fees, your checked bags still need to meet certain size and weight requirements to avoid additional charges.
Weight Limit: Each checked bag must not exceed 50 lbs (23 kg).
Size Limit (Linear Inches): The sum of the length + width + height of your bag must not exceed 62 linear inches (158 cm). This includes handles and wheels!
Pro Tip: Use a tape measure and a luggage scale at home! It's much easier to adjust your packing before you get to the airport.
Tip: Take a sip of water, then continue fresh.
Sub-heading: Overweight and Oversized Baggage Fees
If your bags exceed the standard limits, you'll incur extra charges. These are per bag, per one-way trip.
Overweight Bags (51-100 lbs / 23-45 kg): A fee of $100 (or $75 per bag based on some sources - always check current Southwest website for definitive pricing) will apply. Bags over 100 lbs (45 kg) will generally not be accepted as checked baggage and may need to be shipped via cargo.
Oversized Bags (63-80 linear inches / 160-203 cm): A fee of $125 (or $75 per bag based on some sources - always check current Southwest website for definitive pricing) will apply. Bags exceeding 80 linear inches (203 cm) will generally not be accepted.
Important Note: If your bag is both overweight and oversized, you will likely pay only one combined fee, not two separate ones, but the higher fee usually applies. Always confirm with Southwest's official policy or an agent if you have a bag that falls into both categories.
Step 3: Decoding Southwest's Carry-On and Personal Item Policy
Even with checked bag fees, your carry-on and personal item are still typically free of charge. This is where smart packing can save you money!
Sub-heading: Carry-On Bag Allowance
You are generally allowed one carry-on bag per passenger.
Maximum Dimensions: Your carry-on bag should not exceed 24 x 16 x 10 inches (61 x 41 x 25 cm) (length x width x height), including handles and wheels.
Placement: This bag must fit in the overhead bin.
Weight Limit: Southwest does not publish a specific weight limit for carry-on bags, but you must be able to safely lift and stow it yourself in the overhead compartment. If it's too heavy for you to lift, it's likely too heavy for them.
Sub-heading: Personal Item Allowance
In addition to your carry-on, you can bring one personal item.
Maximum Dimensions: A personal item should not exceed 18.5 x 8.5 x 13.5 inches (47 x 22 x 34 cm).
Examples: This typically includes items like a purse, laptop bag, small backpack, briefcase, or camera bag.
Placement: Your personal item must fit under the seat in front of you.
Sub-heading: Additional Items (Beyond Carry-On and Personal Item)
Certain items do not count towards your one carry-on and one personal item limit:
Outer garments (coats, jackets)
Food for consumption during the flight in disposable packaging
Assistive devices (wheelchairs, crutches, walkers, etc.)
Child restraint devices (car seats) for a ticketed child or when space is available
Diaper bags (when traveling with an infant/child)
Breast pumps and breast milk
Medical devices
Tip: Focus on sections most relevant to you.
Step 4: Special Circumstances and Exceptions
Southwest does offer some exceptions to its standard baggage policies. It's always worth checking if you qualify!
Sub-heading: Fare Classes and Loyalty Programs
Your fare type and Rapid Rewards status can impact your baggage allowance:
Business Select®: Customers flying on a Business Select fare will continue to receive two free checked bags.
Rapid Rewards A-List Preferred Members: These elite members also still get two free checked bags.
Rapid Rewards A-List Members: A-List members will receive their first checked bag for free.
Southwest Rapid Rewards Credit Cardmembers: If you hold a Southwest co-branded credit card, you typically receive your first checked bag for free. Some cards may also extend this benefit to companions on the same reservation. Check your specific credit card benefits!
Sub-heading: Military Personnel
Active duty U.S. military personnel and their dependents traveling on active orders enjoy a more generous baggage allowance.
They are generally exempt from the two-piece baggage limit and will not be subject to excess, oversize, or overweight baggage charges.
However, individual pieces of baggage must not exceed 100 pounds (45 kg) in weight and 80 inches (203 cm) in size (L+W+H).
A valid, current military ID must be presented at check-in.
Sub-heading: Sporting Equipment and Musical Instruments
Southwest has specific policies for these items, which often count as part of your checked baggage allowance.
Many standard sporting equipment items (like golf bags, skis, snowboards) can be checked as one of your free checked bags (if you have that allowance) or count towards your paid allowance, provided they meet standard weight and size limits.
Oversized or overweight fees will apply if they exceed these limits.
For musical instruments, smaller ones can often be carried on if they fit in the overhead bin or under the seat. Larger instruments may require purchasing a separate seat or checking them, incurring potential oversized/overweight fees.
Always check Southwest's specific guidelines for your particular item as some sports equipment (like bicycles or surfboards) may have unique rules and fees.

Step 5: How to Measure and Weigh Your Luggage Accurately
Don't guess! Being precise is key to avoiding last-minute fees.
Sub-heading: Tools You'll Need
Tip: Read slowly to catch the finer details.
Measuring Tape: A flexible one is best for getting accurate dimensions, especially around curves.
Luggage Scale: An absolute must-have. These are inexpensive and can save you a lot of money and stress.
Notebook/Phone: To jot down your measurements.
Sub-heading: Measuring Carry-On Bags
Place Upright: Stand your bag on a flat surface as it would sit on its wheels.
Measure Height: From the very bottom of the wheels (if any) to the highest point of the bag, including the handle if it's not retractable or is in its fully closed position.
Measure Width: Measure across the widest part of the bag, side to side.
Measure Depth: Measure from the front to the back of the bag, including any protruding pockets or handles.
Compare: Ensure your measurements are within the 24 x 16 x 10 inches limit.
Sub-heading: Measuring Checked Bags (Linear Inches)
Lay Flat: Place your bag on its back or front for easier measurement.
Measure Length: From one end to the other, including any handles or wheels that extend beyond the main body.
Measure Width: From side to side, across the widest point.
Measure Height/Depth: Measure the thickness of the bag from front to back, including any pockets.
Calculate Linear Inches: Add your Length + Width + Height measurements together. Ensure the sum is 62 inches or less.
Sub-heading: Weighing Your Bags
Use a Luggage Scale: Hook the scale to your bag's handle and lift it off the ground.
Record Weight: Note the reading.
Distribute Weight: If your bag is overweight, consider redistributing items to another bag or removing non-essential items. Don't try to cram everything into your carry-on if it means exceeding its limits or making it impossible to lift!
Step 6: When and Where to Pay for Luggage
Southwest has specific procedures for paying baggage fees.
At the Airport: Checked baggage fees are typically paid at the airport when you check your bags. You'll do this at the ticket counter or a self-service kiosk.
No Pre-Payment Online: Unlike some other airlines, Southwest generally does not offer the option to pre-pay for checked baggage online.
Credit Cards: Be prepared to pay with a credit card.
Step 7: Smart Strategies to Potentially Reduce or Avoid Baggage Fees
While the "Bags Fly Free" era for most is over, there are still ways to minimize your baggage costs.
Utilize Your Free Carry-On and Personal Item: This is your primary line of defense against checked bag fees. Pack strategically! Roll clothes, use packing cubes, and wear your bulkiest items.
Southwest Rapid Rewards Credit Card: As mentioned, many co-branded Southwest credit cards offer a free checked bag. If you fly Southwest frequently, the annual fee might be offset by the baggage savings.
Achieve A-List Status: If you're a frequent flyer, aiming for A-List or A-List Preferred status through flight activity can unlock free checked bags.
Travel with Business Select Fares: If your company pays for your flights or you value the added perks, Business Select fares include two free checked bags.
Ship Your Luggage: For very heavy or numerous bags, consider a luggage shipping service like My Baggage. This can sometimes be more cost-effective than paying airline excess fees, and it allows you to travel light.
Pack Light: The most obvious, yet often overlooked, strategy. Do you really need those five pairs of shoes? A minimalist approach to packing can save you significant money and hassle.
