Have you ever found yourself staring at your luggage, wondering, just how many bags can I bring on my Southwest flight without breaking the bank? You're not alone! Southwest Airlines is known for its unique "Bags Fly Free" policy (with some important updates, as we'll discuss), which sets it apart from many other carriers. But understanding the nuances of their baggage rules, including size limits, weight restrictions, and special item policies, is crucial for a stress-free travel experience.
This comprehensive guide will walk you through everything you need to know about Southwest Airlines' baggage policy, step-by-step, ensuring you're well-prepared for your next adventure.
Step 1: Understand the "Bags Fly Free" Philosophy (and its Recent Evolution)
Let's start with the heart of Southwest's baggage appeal: the "Bags Fly Free" motto. For a long time, Southwest was celebrated for allowing every ticketed passenger to check two bags for free, provided they met the standard size and weight limits. This was a significant advantage over other airlines that often charge for even the first checked bag.
However, it's vital to note a recent change! For flights booked on or after May 28, 2025, Southwest has introduced new fare categories that impact the "Bags Fly Free" policy for some passengers.
Sub-heading: Who Still Gets Free Bags?
Business Select and A-List Preferred Members: If you're flying with a Business Select fare or have A-List Preferred status in the Rapid Rewards program, you continue to enjoy two free checked bags. This is a great perk for frequent flyers and those who prioritize flexibility and amenities.
A-List Members and Rapid Rewards Credit Card Holders: If you're an A-List member or hold a Southwest Rapid Rewards credit card, you are now entitled to one free checked bag or a "bag credit." This is still a valuable benefit, though a reduction from the previous two.
All Other Passengers: For flights booked after May 28, 2025, if you don't fall into the categories above, your checked bags are no longer free and will incur a fee. It's crucial to factor this into your travel budget.
Key Takeaway: Always check your specific fare type and Rapid Rewards status when booking your flight to understand your exact baggage allowance.
Step 2: Grasping the Standard Baggage Dimensions and Weight Limits
Whether your bags fly free or you're paying a fee, there are universal size and weight restrictions that apply to all checked baggage on Southwest Airlines. Adhering to these limits is paramount to avoid unexpected charges at the airport.
Sub-heading: Checked Baggage Limits
For each checked bag, remember these crucial numbers:
Maximum Weight: 50 pounds (22.7 kg) per bag.
Maximum Size (Linear Dimensions): 62 inches (157.5 cm). This is calculated by adding the length, width, and height of your bag, including handles and wheels.
Pro Tip: Before heading to the airport, measure and weigh your bags! A simple luggage scale can save you from a costly surprise. Many travel supply stores also sell soft measuring tapes that are perfect for checking linear dimensions.
Sub-heading: Carry-On Baggage Limits
Southwest's carry-on policy is generally quite generous, allowing you to bring one carry-on bag and one personal item.
Carry-On Bag: This bag goes in the overhead bin.
Maximum Dimensions: 24 x 16 x 10 inches (approx. 61 x 40 x 25 cm).
Weight Limit: There is no specified weight restriction for carry-on items, but you must be able to lift it into the overhead bin unassisted.
Personal Item: This item must fit under the seat in front of you.
Maximum Dimensions: 16.25 x 13.5 x 8 inches (approx. 41 x 34 x 20 cm).
Weight Limit: No specified weight limit.
Important Note: If you are traveling with a pet carrier, it will count as either your carry-on bag or your personal item.
Step 3: Navigating Overweight, Oversize, and Additional Baggage Fees
Exceeding the standard limits can lead to additional charges. Be prepared for these potential costs.
Sub-heading: Overweight Baggage Fees
If your checked bag weighs more than 50 pounds but does not exceed 100 pounds:
51-70 lbs: Generally, a fee of $100-$150 per bag, per way.
71-100 lbs: Generally, a fee of $125-$200 per bag, per way.
Over 100 lbs: Bags exceeding 100 pounds are not permitted as checked baggage and must be shipped as cargo.
Sub-heading: Oversize Baggage Fees
If your checked bag's linear dimensions exceed 62 inches but do not exceed 80 inches:
63-80 inches: Generally, a fee of $125-$200 per bag, per way.
Over 80 inches: Bags exceeding 80 inches are not permitted as checked baggage and must be shipped as cargo.
Note: If a bag is both overweight and oversized, only one fee typically applies, generally the higher of the two. Always verify the most current fees on the official Southwest Airlines website as they are subject to change.
Sub-heading: Additional Checked Baggage Fees
Once you've utilized your allowed free checked bags (if any, based on your fare type and status), any additional checked bags will incur a fee.
Third (and Subsequent) Checked Bags: Typically $75 per bag, per way.
Step 4: Special Baggage: Sports Equipment, Musical Instruments, and More
Southwest Airlines has specific policies for various special items. It's crucial to understand these rules, as they can differ from standard baggage.
Sub-heading: Sports Equipment
Many types of sports equipment can be checked as part of your standard baggage allowance, provided they meet the weight and size limits. However, some items have specific rules or may incur additional fees if they exceed the limits.
Golf Clubs: A golf bag (including clubs, balls, and shoes) counts as one checked bag. If it's oversized or overweight, standard fees apply.
Skis and Snowboards: Skis and snowboards (along with poles and boots) generally count as one checked bag. While they often exceed the 62-inch linear dimension, Southwest often waives the oversized fee for these items, but weight limits still apply.
Bicycles: Bicycles are accepted when properly packed in a bike box. Standard baggage fees and overweight/oversize fees apply.
Surfboards: Accepted with a fee (typically $75) and subject to size limits (often up to 80 inches). On Hawaiian inter-island flights, surfboards may travel free if substituted for one of your two free bags.
Always check Southwest's "Special Baggage & Sports Equipment" page for the most up-to-date and specific rules for your equipment.
Sub-heading: Musical Instruments
Musical instruments can often be carried on or checked, depending on their size and fragility.
Carry-on Instruments: Smaller instruments (like violins, guitars) may be carried on if they fit in the overhead bin or under the seat. If they exceed standard carry-on dimensions but still fit safely in the cabin, they may be allowed if space is available.
Seat Purchase for Instruments: For larger instruments that cannot be stowed safely in the overhead bin or under a seat (e.g., cellos), you may purchase an additional seat for the instrument. Specific rules apply for securing the instrument in the seat.
Checked Instruments: Instruments can be checked as baggage. If they exceed standard baggage dimensions or weight, overweight/oversize fees will apply. Extremely large or heavy instruments (e.g., those over 150 linear inches or 165 pounds) may not be accepted.
Recommendation: For valuable or fragile instruments, consider purchasing an extra seat or using a specialized shipping service to ensure their safe transport.
Step 5: Understanding Pet Travel
Traveling with your furry friend on Southwest? There are specific guidelines for pets in the cabin.
Accepted Animals: Southwest only accepts small, vaccinated domestic cats and dogs in the cabin on domestic flights. Pets must be at least eight weeks old.
Pet Carrier: The pet must be in an approved pet carrier that fits under the seat in front of you. The carrier counts as either your carry-on bag or your personal item.
Maximum Carrier Dimensions: 8.5 inches high x 18.5 inches long x 13.5 inches wide (approx. 21.59 x 46.99 x 34.29 cm).
Fees: There is a pet fare (e.g., $125 each way, subject to change) that must be paid at the airport ticket counter.
Reservations: Space for pets is limited, so it's highly recommended to make a reservation in advance by calling Southwest Airlines.
Important Restrictions: Pets are not accepted on flights to or from Hawaii or on international itineraries. Pets must remain in their carrier with the door closed and stowed under the seat for the entire flight.
Step 6: Tips for a Smooth Baggage Experience
To ensure your baggage journey is as seamless as possible, keep these tips in mind:
Sub-heading: Pre-Flight Preparations
Measure and Weigh: This cannot be stressed enough! Use a tape measure and a luggage scale to confirm your bags meet the limits.
Know Your Fare/Status: Understand your specific baggage allowance based on your ticket type and Rapid Rewards status for flights booked after May 28, 2025.
Pack Smart: Distribute weight evenly across bags if you're close to the limit. Consider rolling clothes to save space.
Label Your Bags: Always put a sturdy luggage tag with your name, phone number, and email address on the outside of your checked bags. Consider putting a copy of your itinerary inside as well.
Self-Tagging: At select airports, you can use self-tagging kiosks to print your bag tags, saving time at the counter.
Sub-heading: At the Airport
Arrive Early: Especially if you're checking bags, allow ample time at the airport. Baggage check-in typically closes 45 minutes before departure.
Verify Fees: If you anticipate paying for bags, have your payment method ready.
Keep Valuables and Essentials in Your Carry-On: Always pack medications, important documents, electronics, and any irreplaceable items in your carry-on.
Gate Checking: If your carry-on is too big or the overhead bins are full, Southwest staff may offer to gate-check your bag. This is usually free of charge, but your bag will be returned at baggage claim upon arrival.
Step 7: What to Do if Your Bag is Lost or Damaged
While rare, baggage issues can occur. Knowing the steps to take can alleviate stress.
Report Immediately: If your bag is lost or damaged, report it to a Southwest Airlines representative at the airport baggage claim area before leaving. Do not leave the airport without filing a report.
File a Claim: You will need to complete a claim form. Be prepared to provide details about your bag and its contents.
Keep Records: Retain copies of your baggage claim tags, flight itinerary, and any receipts for items in your luggage.
Follow Up: Stay in contact with Southwest Airlines for updates on your claim.
