Step 2: Understanding Southwest's Checked Baggage Policy
Southwest Airlines has long been known for its customer-friendly baggage policy, particularly when it comes to checked bags. While some changes have been implemented recently regarding the "Bags Fly Free" policy for all fares, the core weight and size limits remain.
Sub-heading: The Standard Allowance
For most passengers, the standard checked baggage allowance on Southwest Airlines is as follows:
Two (2) checked bags are typically permitted.
Each bag must not exceed 50 pounds (23 kg) in weight.
Each bag must not exceed 62 linear inches (length + width + height) in total dimensions.
It's crucial to note that as of May 28, 2025, Southwest has adjusted its free checked bag policy for most fares. Previously, all passengers enjoyed two free checked bags. Now, generally:
First checked bag: Fee applies for most fares ($35).
Second checked bag: Fee applies for most fares ($45).
However, some fare types and Rapid Rewards members may still qualify for free checked bags. Always check your specific ticket details or Southwest's official "Optional Travel Charges" page for the most up-to-date and accurate information regarding fees for your specific booking.
Sub-heading: Who Still Gets Free Checked Bags?
While the universal "Bags Fly Free" policy has shifted, certain passengers can still enjoy the benefit of free checked baggage:
Business Select Travelers: Passengers who book the Business Select fare will still receive two free checked bags.
Rapid Rewards A-List Preferred Members: These elite members of Southwest's loyalty program are entitled to two free checked bags.
Rapid Rewards A-List Members: A-List members typically receive one free checked bag.
Southwest Co-branded Credit Cardholders: Many Southwest credit cardholders can also receive one free checked bag. Ensure your Rapid Rewards account number is linked to your reservation.
Active-duty Military Personnel: With a valid military ID, active-duty military personnel are exempt from the two-piece baggage limit and will not be subject to excess, oversize, or overweight baggage charges, provided no piece exceeds 100 pounds in weight and 80 inches in total dimensions.
Step 3: Navigating Overweight and Oversized Baggage
So, what happens if your bag tips the scales or bulges beyond the standard dimensions? Southwest has clear guidelines and associated fees.
QuickTip: Use posts like this as quick references.
Sub-heading: Overweight Baggage Fees
If your checked bag weighs more than 50 pounds but less than 100 pounds, you will incur an overweight baggage fee.
51 to 70 pounds (24 kg to 32 kg): A fee of approximately $100 - $150 USD per bag applies.
71 to 100 pounds (33 kg to 45 kg): A fee of approximately $200 USD per bag applies.
Bags exceeding 100 pounds (46 kg) will generally NOT be accepted as checked baggage. Such items may need to be shipped via Southwest Cargo if you are a "Known Shipper."
Important Note: This fee is in addition to any standard checked bag fees that may apply to your fare. So, if your fare requires you to pay for the first checked bag, and that bag is also overweight, you'll pay both the standard bag fee and the overweight fee.
Sub-heading: Oversized Baggage Fees
If your checked bag's total linear dimensions (length + width + height) exceed 62 inches, but are not more than 80 inches, it's considered oversized.
63 to 80 inches (158 cm to 203 cm): A fee of approximately $200 USD per bag applies.
Bags exceeding 80 inches will generally NOT be accepted as checked baggage.
Keep in mind: If your bag is both oversized and overweight, only one $200 charge applies, provided the bag does not exceed 100 pounds.
Step 4: Understanding Carry-On and Personal Item Allowances
While Southwest is known for its checked bag policy, it's equally important to know the rules for what you can bring into the cabin.
Sub-heading: Carry-On Bag
Each passenger is allowed one carry-on bag.
Size Limit: Your carry-on bag should not exceed 10 x 16 x 24 inches (25.4 x 40.64 x 60.96 cm) including handles and wheels.
Weight Limit: Southwest Airlines does not impose a specific weight limit for carry-on bags. However, you must be able to lift and stow the bag in the overhead bin yourself. If you cannot, it should be checked.
Sub-heading: Personal Item
In addition to your carry-on, you are allowed one personal item.
Examples: This typically includes items like a purse, briefcase, laptop bag, or small backpack.
Size Limit: Your personal item should be of a size that can fit under the seat in front of you. Common dimensions are around 16.25 x 13.5 x 8 inches (41 x 34 x 21 cm).
Weight Limit: There is no specified weight restriction for personal items.
Tip: Reread slowly for better memory.
Step 5: Special Items and Exceptions
Southwest understands that some travelers have unique needs or specialized equipment.
Sub-heading: Sports Equipment
Many types of sports equipment are accepted as checked baggage.
Standard checked bag fees, size, and weight limits generally apply. However, some specific items may have different rules. For instance:
Surfboards: Can be substituted for one checked bag, but if they exceed 50 pounds, an overweight fee may apply. Length and width restrictions might be waived for surfboards on inter-island Hawaii flights.
Bicycles: Must be in a hard-sided bicycle box that falls within the 62-inch and 50-pound limits.
Always check Southwest's "Special Baggage & Sports Equipment" page for detailed information on your specific item.

Sub-heading: Assistive Devices
Assistive devices for individuals with disabilities (e.g., wheelchairs, crutches, walkers) are not counted against your carry-on or checked baggage limits and are generally transported free of charge.
Sub-heading: Traveling with Pets
Pets in carriers are permitted in the cabin on domestic flights, but the carrier will count as either your carry-on or personal item. There is a pet fee that applies, and specific size requirements for the carrier. Pets cannot be checked into the hold with Southwest.
Step 6: Practical Tips for a Smooth Baggage Experience
Now that you know the rules, here are some actionable tips to make your travel experience even smoother:
Invest in a Luggage Scale: These inexpensive tools are your best friend for avoiding overweight bag fees. Weigh your bags at home!
Measure Your Bags: Don't just eyeball it. Use a tape measure to ensure your bags meet the linear inch requirements, especially for checked luggage.
Pack Strategically:
Roll your clothes to save space.
Wear your heaviest items (like boots or jackets) on the plane.
Utilize packing cubes to organize and compress your belongings.
Consider shipping non-essential items ahead of time if you have a lot of luggage.
Distribute Weight Evenly: If you're close to the limit, try to shift heavier items between your bags.
Know Your Fare Type: Reconfirm what baggage allowance is included with your specific Southwest fare when booking.
Check-In Online: While you'll still need to drop off checked bags, checking in online can save you time at the airport.
Arrive Early: Especially if you anticipate any baggage issues or need to pay fees, give yourself ample time at the airport.
Step 7: What to Do if Your Bag is Overweight or Oversized at the Airport
Even with the best intentions, sometimes a bag might be over the limit. Don't panic!
QuickTip: Return to sections that felt unclear.
Option 1: Repack at the Counter: If you have time and aren't too far over, you might be able to shift items to another bag (if you have one with space) or to your carry-on/personal item.
Option 2: Pay the Fee: If repacking isn't an option or you're significantly over, be prepared to pay the applicable overweight or oversized baggage fee. It's usually cheaper to do this at the counter than to deal with last-minute shipping.
Option 3: Consider Shipping: For extremely heavy or large items that exceed Southwest's maximum acceptance limits, you might need to explore third-party baggage shipping services.
Step 8: Understanding International vs. Domestic Baggage Policies (Southwest Specifics)
Southwest primarily operates domestic flights within the United States and to a few international destinations in the Caribbean and Mexico. While the core baggage policy remains consistent, there are a couple of points to keep in mind for international itineraries:
Customs Procedures: If your itinerary includes an international flight into the United States, you must claim all checked luggage from baggage claim upon arrival in the U.S., regardless of your final destination. After clearing Customs, you'll be required to re-check your luggage.
Pet Travel: Pets are generally not allowed to travel in-cabin on international Southwest flights.
Always confirm specific regulations for your international destination, as some countries may have additional restrictions or requirements.
