Hey there, savvy traveler! Planning a trip with Southwest Airlines and wondering about those pesky baggage weight limits? You're in the right place! Nobody wants to get to the airport only to discover their carefully packed suitcase is an overweight behemoth, leading to unexpected fees and a scramble to rearrange belongings. Let's break down exactly what you need to know about Southwest's baggage policy, pound by pound, so you can pack with confidence and cruise through check-in.
Step 1: Let's Talk About Your Bags!
First things first, what kind of bags are you planning to bring? Are we talking about a small carry-on for a quick weekend getaway, or are you packing for a longer adventure with multiple checked bags? Your answer here will determine which rules apply to you.
Southwest Airlines has specific guidelines for:
-
Carry-on Bags: These are the bags you take with you into the cabin.
-
Personal Items: Smaller items that fit under the seat in front of you.
-
Checked Bags: The bags that go in the cargo hold of the plane.
Understanding these distinctions is crucial, as the weight and size limits vary significantly for each type.

Step 2: Understanding Southwest's Checked Baggage Policy
This is where the rubber meets the road for most travelers concerned about weight. Southwest has historically been known for its generous "Bags Fly Free" policy, but it's important to note that this has changed for most travelers for reservations booked or voluntarily changed on or after May 28, 2025. While certain fare types and elite status still offer free checked bags, many passengers will now incur fees.
Sub-heading: Standard Checked Bag Weight Limit
For each standard checked bag, whether it's free or paid, the weight limit on Southwest Airlines is:
-
50 pounds (22.7 kg)
This is a firm limit, and exceeding it will result in additional fees.
Sub-heading: Standard Checked Bag Size Limit
In addition to weight, there are size restrictions for checked bags:
QuickTip: Let each idea sink in before moving on.
-
62 linear inches (length + width + height)
To calculate this, simply measure the length, width, and height of your bag (including wheels and handles!) and add those three numbers together. If the sum is over 62 inches, your bag is considered oversized, and fees will apply.
Sub-heading: The (New) Reality of Checked Bag Fees
As of May 28, 2025, for most fares:
-
First Checked Bag: A fee typically applies (e.g., around $35).
-
Second Checked Bag: A fee typically applies (e.g., around $45).
-
Third and Subsequent Bags: Expect higher fees (e.g., around $75 per bag).
Who still gets free checked bags?
-
Business Select fares and Rapid Rewards A-List Preferred Members generally receive two free checked bags.
-
Rapid Rewards A-List Members and Southwest Rapid Rewards Credit Cardmembers often get their first checked bag free.
-
Hawaii residents traveling between the islands also continue to receive two free checked bags.
Always double-check your specific fare type and Rapid Rewards status when booking to confirm your baggage allowance.
Step 3: Navigating Overweight and Oversized Baggage Fees
So, what happens if your bag is a little too heavy or a little too large? Southwest will assess additional fees.
Sub-heading: Overweight Baggage Fees
If your checked bag weighs more than 50 pounds but does not exceed 100 pounds:
-
51 to 99 pounds (23.1 to 45.3 kg): An additional fee of $75 will be charged per bag, in addition to any standard checked bag fees.
-
Over 100 pounds (45.3 kg): Items weighing over 100 pounds will not be accepted as checked baggage. You'll need to look into shipping these items via Southwest Cargo or another freight service.
Sub-heading: Oversized Baggage Fees
If your checked bag is larger than 62 linear inches but does not exceed 80 linear inches:
QuickTip: Skim the intro, then dive deeper.
-
63 to 80 inches: An additional fee of $75 will be charged per bag, in addition to any standard checked bag fees.
-
Over 80 inches: Items larger than 80 linear inches cannot be checked as baggage. Similar to overweight items, these may need to be shipped as cargo.
Important Note: A single bag can be subject to both overweight and oversized fees if it exceeds both limits. For example, a bag weighing 60 pounds and measuring 65 linear inches would incur both an overweight fee and an oversized fee.
Step 4: Understanding Carry-on and Personal Item Rules
While Southwest is very specific about checked bag weight, their carry-on policy is a bit different.
Sub-heading: Carry-on Bag Weight Limit
-
Southwest Airlines does not specify a weight limit for carry-on bags.
-
However, the unofficial rule is that you must be able to lift the bag into the overhead bin yourself, unassisted. If you can't, it might need to be checked.
Sub-heading: Carry-on Bag Size Limit
-
Your carry-on bag must fit in the overhead bin. The general dimensions are typically around 24 x 16 x 10 inches (61 x 41 x 25 cm), including wheels and handles. Always verify the most current dimensions on Southwest's website. If it doesn't fit, it will be gate-checked (and potentially subject to checked bag fees if it's your third bag, for example).
Sub-heading: Personal Item
-
You are also allowed one personal item that must fit under the seat in front of you.
-
Examples include a purse, briefcase, laptop bag, or a small backpack.
-
There are no specific weight limits for personal items, and while specific size dimensions are not always listed, it must comfortably fit under the seat.
Step 5: Tips for Staying Within Limits and Avoiding Fees
-
Invest in a Luggage Scale: This is your best friend for avoiding overweight bag fees. Weigh your bags at home before you leave for the airport.
-
Pack Smart: Roll your clothes, use packing cubes, and wear your heaviest items (like bulky jackets or boots) on the plane.
-
Consolidate: If you're close to the limit on one bag, see if you can shift some items to another checked bag (if you have allowance) or your carry-on/personal item.
-
Consider Shipping: For truly oversized or overweight items that won't fit within limits, or if you simply have too many bags, look into shipping services. This can sometimes be more cost-effective than airline fees.
-
Know Your Fare: As mentioned, Southwest's policy has changed. Be aware of the baggage allowance included with your specific fare type and any Rapid Rewards status you hold.
-
Check Southwest's Official Website: Airline policies can change! Always refer to the official Southwest Airlines website or contact their customer service for the most up-to-date information before your trip.
By following these steps and keeping a close eye on your packing, you can ensure a smooth and stress-free start to your Southwest Airlines journey!
