| How To Pack For Southwest Airlines |
Step 1: Understand Southwest's Baggage Policies (The Crucial First Step!)
Before you even think about what to put in your suitcase, you need to know what Southwest allows and, more importantly, what it charges for. This is where many travelers get caught off guard!
1.1 Carry-On Baggage: Your Free Ride
Southwest Airlines is quite generous with its carry-on allowance, and this remains a fantastic way to avoid checked bag fees if you can pack light.
One Carry-On Bag: You're allowed one carry-on bag.
Dimensions: It must not exceed 24 x 16 x 10 inches (61 x 40 x 25cm), including handles and wheels.
Weight: There is no specified weight restriction for carry-on items, but you must be able to lift it into the overhead bin yourself.
One Personal Item: In addition to your carry-on, you can bring one small personal item.
Dimensions: This item must not exceed 18.5 x 8.5 x 13.5 inches (47 x 22 x 34 cm).
Examples: Think of items like a purse, briefcase, laptop bag, or a small backpack.
Placement: This item must fit under the seat in front of you.
1.2 Checked Baggage: The New Landscape
This is where the significant changes have occurred for Southwest as of May 28, 2025.
Standard Allowance (Effective May 28, 2025):
For Basic, Wanna Get Away Plus®, and Anytime fares booked or changed on or after May 28, 2025, you will now pay for checked bags.
First checked bag: $35
Second checked bag: $45
Dimensions: Each checked bag must not exceed 62 linear inches (length + width + height).
Weight: Each checked bag must not exceed 50 lbs (22.7 kg).
Who Still Gets Free Checked Bags?
Business Select®: Two free checked bags.
Rapid Rewards® A-List Preferred members: Two free checked bags.
Rapid Rewards® A-List members: One free checked bag.
Rapid Rewards® Credit Cardmembers: One free checked bag (for the cardmember and up to eight additional passengers on the same reservation, provided the Rapid Rewards number is included at booking).
Excess, Overweight, and Oversized Baggage Fees:
Overweight (51-70 lbs): $100 per bag.
Overweight (71-100 lbs): $125 per bag (some sources indicate $200 per bag, so always double-check the latest Southwest policy directly).
Oversized (63-80 inches): $125 per bag.
Bags over 80 inches or 100 lbs may not be accepted.
Important Note: If a bag is both oversized and overweight, only one fee (the higher one) typically applies, but check for specific combinations.
1.3 Special Items (Sports Equipment, Musical Instruments, etc.)
Many special items can be checked as part of your standard baggage allowance if they meet the size and weight limits. However, some larger or unusual items may incur additional fees. Always check Southwest's specific policies for items like:
Golf clubs
Ski/snowboard equipment
Bicycles
Surfboards
Musical instruments
Step 2: Plan Your Wardrobe & Essentials (The Art of Strategic Packing)
QuickTip: A careful read saves time later.
Now that you know the rules, it's time to get strategic about what you pack.
2.1 The Capsule Wardrobe Approach
Focus on Versatility: Choose clothing items that can be mixed and matched to create multiple outfits. Think neutral colors with a few accent pieces.
Layer Up: Layers are your best friend, especially if traveling to varying climates. They allow you to adjust to temperature changes without packing bulky items.
Check the Weather: Seriously, do it! A quick check of your destination's forecast will prevent you from packing too much or too little of certain types of clothing.
Wear Your Heaviest Items: Planning to bring a bulky jacket or heavy boots? Wear them on the plane to save precious space and weight in your luggage.
2.2 The "Must-Haves" List
Before you start throwing things into a bag, make a list. This helps prevent overpacking and forgetting essentials.
Documents: Passport/ID, boarding pass, reservation confirmations, travel insurance. Keep these in your personal item!
Medications: Any prescription or over-the-counter medications you need. Keep them in their original containers in your carry-on.
Toiletries: Travel-sized versions of toothpaste, shampoo, conditioner, soap, lotion, etc. Remember the TSA 3-1-1 rule for liquids in your carry-on! (More on this below.)
Electronics: Phone, charger, headphones, power bank. Pack these in your personal item for easy access and to keep them safe.
Comfort Items: A neck pillow, eye mask, earplugs, a good book or entertainment for the flight.
Step 3: Master the Art of Packing (Space-Saving Techniques)
Now for the hands-on part! How you physically pack your bag makes a huge difference.
3.1 Rolling vs. Folding
Rolling is Often Superior: For most clothing items, rolling them tightly can save space and help prevent wrinkles. It also allows you to see all your clothes at a glance.
Strategic Folding: For more delicate items or structured garments, careful folding might still be best. Use the "bundle wrapping" method for suits or dresses.
3.2 Utilize Packing Aids
Packing Cubes: These are game-changers! They compress your clothes, keep them organized, and make it easy to separate outfits or types of clothing. Plus, they make unpacking a breeze.
Compression Bags: These can significantly reduce the volume of bulky items like sweaters or jackets. Just be mindful of weight limits if using them for checked bags.
Shoe Bags: Always pack shoes in individual bags to prevent dirt from getting on your clothes. Stuff socks or small items inside your shoes to maximize space.
3.3 The "Heavy at the Bottom, Light at the Top" Rule
Bottom Layer: Place heavier, sturdier items (like shoes, toiletries, folded jeans) at the bottom of your suitcase, near the wheels, to maintain stability.
Middle Layer: Your rolled or folded clothes go here.
Top Layer: Lighter, more delicate items, and anything you might need to access quickly (like a change of clothes if you have a connecting flight, or pajamas for your first night).
3.4 The 3-1-1 Rule for Carry-On Liquids (TSA Compliant)
QuickTip: Look for patterns as you read.
This is a critical rule for carry-on bags to ensure a smooth security experience:
3.4 ounces (100 milliliters): All liquids, gels, aerosols, creams, and pastes must be in containers of 3.4 ounces (100 milliliters) or smaller.
1 Quart-sized bag: All these containers must fit comfortably within one clear, quart-sized, resealable plastic bag.
1 Bag per passenger: You are limited to one such bag per passenger.
Pro Tip: If you use larger containers for items like shampoo or lotion, these must go in your checked bag.
Step 4: Double-Check and Weigh Your Bags (Avoid Surprises!)
This step is often overlooked but can save you a lot of hassle and money at the airport.
4.1 Invest in a Luggage Scale
These small, portable scales are inexpensive and invaluable. Weigh your bags before you leave for the airport to ensure you're within Southwest's limits.
Accuracy is Key: Even being a pound or two over can result in significant fees.
4.2 Measure Your Bags
Use a tape measure to confirm your carry-on and personal item dimensions. Don't forget to include wheels and handles in your measurements!
If your bag is close to the limit, a slightly overstuffed bag can become oversized.
4.3 What to Do If You're Over
Shift Items: If a checked bag is overweight, try to shift some heavier items to your carry-on (as long as they comply with carry-on rules and don't make your carry-on too heavy to lift).
Wear More: If feasible, wear extra layers or heavier shoes.
Ship It: For very heavy or oversized items, consider shipping them separately via a courier service. This can sometimes be cheaper than airline excess baggage fees.
Step 5: Last-Minute Preparations & Airport Tips
You're almost there! A few final checks and tips will ensure a seamless departure.
5.1 Keep Essentials Accessible
In your Personal Item: Boarding pass, ID, wallet, phone, chargers, medications, a light snack, and any in-flight entertainment.
At the Top of your Carry-On: Your 3-1-1 liquids bag for easy removal at security, and perhaps a light jacket.
5.2 Pack Smart for Security
QuickTip: Treat each section as a mini-guide.
Electronics: Laptops and other large electronics often need to be removed from your bag for separate screening. Pack them in a way that makes this easy.
Shoes: You might be required to remove your shoes at security. Wear slip-on shoes for convenience.
5.3 Boarding Process with Southwest
Southwest has an open seating policy. Boarding is based on your check-in time and assigned boarding group (A, B, or C) and position (1-60).
Early Check-in is advantageous: The earlier you check in (24 hours before your flight), the better your boarding position, which means better overhead bin space selection. This is especially important if you're relying on your carry-on!

Holding Business Select® fare.
Being a Rapid Rewards® A-List Preferred member.
Being a Rapid Rewards® A-List member (one free bag).

How to check my bag's dimensions for Southwest Airlines?
Use a tape measure to measure the length, width, and height of your bag, including any wheels and handles. For checked bags, add these three measurements together to get the "linear inches" and ensure it's 62 inches or less. For carry-on and personal items, check each dimension individually against the limits.
How to pack shoes efficiently in a suitcase?

QuickTip: Don’t just scroll — process what you see.
How to maximize space in a carry-on bag for Southwest?
Roll your clothes tightly, use packing cubes or compression bags, wear your bulkiest items, and utilize all available space, including stuffing small items into shoes or hats.
How to pack medications for a Southwest flight?
Keep all prescription and essential over-the-counter medications in their original containers in your carry-on bag. This ensures you have immediate access and avoids issues if your checked bag is delayed or lost. Liquid medications exceeding 3.4 oz are allowed in your carry-on if medically necessary, but you should declare them to TSA.
How to handle oversized or overweight bags for Southwest Airlines?
If your bag exceeds 50 lbs or 62 linear inches, you will incur additional fees (e.g., $100-$125 for overweight, $125 for oversized as of May 28, 2025). Consider shifting items to a carry-on or shipping them separately if the fees are prohibitive.
How to pack electronics for a Southwest flight?
Pack laptops, tablets, and other large electronics in your personal item or carry-on bag. Make sure they are easily accessible as you may need to remove them for security screening. Spare lithium batteries must always be in your carry-on bag, not checked baggage.
How to keep clothes from wrinkling when packing for Southwest?
Rolling clothes tightly can help reduce wrinkles. For items prone to wrinkling, consider using packing folders or the bundle wrapping method where you wrap clothes around a central core. Choose wrinkle-resistant fabrics like knits or synthetic blends.
How to choose the right luggage for Southwest Airlines?
Opt for lightweight luggage to maximize your packing weight allowance. For carry-on bags, choose one that adheres strictly to the 24 x 16 x 10 inch dimensions. For checked bags, a soft-sided bag might offer a bit more flexibility for squeezing in items, but always ensure it's within the 62 linear inch and 50 lb limits.
