Have you ever found yourself at the airport, frantically shifting items between your checked bag and carry-on, praying your suitcase doesn't tip the scales into "overweight" territory? We've all been there! The dread of unexpected baggage fees can cast a shadow over even the most exciting travel plans. When flying with Southwest Airlines, knowing their baggage allowance is key to a smooth and stress-free journey.
Let's dive deep into understanding exactly how many pounds your suitcase can be for Southwest Airlines, along with all the essential details to avoid those pesky extra charges!
Understanding Southwest Airlines Baggage Policy: A Step-by-Step Guide
Southwest Airlines has long been known for its customer-friendly policies, including its generous baggage allowance. However, recent changes (effective May 28, 2025) mean it's more important than ever to be aware of the specifics, especially regarding checked bags.
Step 1: Are You Eligible for Free Checked Bags?
This is where your journey to baggage bliss begins! Did you know that Southwest's famous "Bags Fly Free" policy has recently undergone some changes? While many still associate Southwest with complimentary checked bags, this benefit now largely depends on your fare class or loyalty status.
For reservations booked and ticketed on or after May 28, 2025, the "Bags Fly Free" policy is primarily extended to:
Business Select passengers.
Rapid Rewards A-List Preferred members.
Rapid Rewards A-List members (for one free checked bag).
Military service members (with valid ID).
Hawaii residents traveling between islands (based on primary mailing address).
If you fall into one of these categories, you're generally entitled to two free checked bags.
For other fare classes (such as Basic, Wanna Get Away Plus, and Anytime) booked on or after May 28, 2025, checked baggage fees may apply. It's crucial to check your specific fare details when booking.
Tip: Always double-check your booking confirmation or the Southwest Airlines website for the most up-to-date information on your specific fare's baggage allowance.
Step 2: Decoding the Checked Baggage Weight Limit
Alright, let's get to the crucial number! For each standard checked bag on Southwest Airlines, the maximum weight allowed is:
50 pounds (22.68 kg)
This applies whether you're getting your bags for free or paying a fee. Any bag exceeding this limit will incur an overweight baggage fee.
Sub-heading: What if my bag is over 50 pounds but under 100 pounds?
If your checked bag weighs between 51 and 99 pounds, it will be considered overweight baggage.
An additional fee of $75 per bag will apply. This fee is in addition to any standard checked bag fees that might apply to your fare class.
Sub-heading: What if my bag is 100 pounds or more?
Southwest Airlines generally will not accept any item weighing more than 100 pounds as checked baggage. Such items would need to be shipped as Air Cargo.
Important Note: This limit also applies to most sporting equipment and musical instruments. Always check specific policies for these items.
Step 3: Understanding Checked Baggage Size Limits
Beyond weight, size matters! Each checked bag must also adhere to specific dimensions.
The maximum linear dimensions (length + width + height) per checked piece of luggage must not exceed:
62 inches (157 cm)
Sub-heading: What if my bag is larger than 62 inches but under 80 inches?
If your checked bag has linear dimensions between 63 and 80 inches, it will be considered oversized baggage.
An additional fee of $75 per bag will apply. Again, this fee is in addition to any standard checked bag fees.
Sub-heading: What if my bag is over 80 inches?
Southwest Airlines will not accept any item with linear dimensions exceeding 80 inches as checked baggage.
Step 4: Navigating Carry-On and Personal Item Allowances
While checked bags have strict weight limits, Southwest's policy for carry-on and personal items is a bit more flexible in terms of weight, though size is still key.
Sub-heading: Carry-On Bag
You are allowed one carry-on bag per passenger.
Size Limit: Your carry-on bag must not exceed the dimensions of:
24 inches (L) x 16 inches (W) x 10 inches (H)
This includes handles and wheels.
Weight Limit: Southwest Airlines does not impose a specific weight limit for carry-on bags. The general rule is that you must be able to lift your bag into the overhead compartment unassisted. If you can't, it should be checked.
Sub-heading: Personal Item
In addition to your carry-on, you are allowed one personal item. This typically includes things like a:
Purse
Briefcase
Laptop bag
Small backpack
Diaper bag
Camera bag
Pillows, blankets
Size Limit: While not as strictly defined as carry-ons, a personal item should be able to fit under the seat in front of you. Common suggested dimensions are around:
18.5 inches (L) x 8.5 inches (W) x 13.5 inches (H)
Weight Limit: Similar to carry-ons, there isn't a stated weight limit, but it must fit comfortably under the seat.
Step 5: How to Avoid Overweight and Oversized Baggage Fees
Nobody likes unexpected fees! Here are some strategies to ensure your bags are within Southwest's limits:
Sub-heading: Pack Smart and Light
Invest in a luggage scale: These are relatively inexpensive and can save you a lot of hassle at the airport. Weigh your bags before you leave for the airport.
Wear your heaviest items: If you're packing bulky shoes or a heavy jacket, wear them on the plane instead of packing them.
Roll, don't fold: Rolling your clothes can sometimes save space, allowing for a more compact pack.
Consider a capsule wardrobe: Plan outfits that mix and match to reduce the number of items you need to bring.
Leave non-essentials behind: Do you really need that extra pair of heels or that third book? Be ruthless in your packing!
Travel-sized toiletries: Decant liquids into smaller containers or buy travel-sized versions.
Sub-heading: Distribute Weight Evenly
If you're traveling with a companion, try to distribute heavier items between your bags. Remember, the 50 lb limit applies per bag, not per person across all bags.
Sub-heading: Consider Shipping Ahead
For very heavy or oversized items that won't fit within the limits, consider shipping them to your destination via a postal service or a luggage shipping company. This can sometimes be more cost-effective than airline fees, especially for truly excessive items.
Sub-heading: Understand Fare Class Benefits
As mentioned in Step 1, if you frequently fly Southwest, consider aiming for A-List or A-List Preferred status, or purchasing Business Select fares, as these often include free checked bags.
