Traveling can be stressful, especially when it comes to packing your luggage. One of the most common concerns for travelers is understanding the rules for checked baggage. Each airline has different requirements. This article will explain in detail the checked baggage size limit on Southwest Airlines. The information will help you avoid problems at the airport and save time and money.
What Is Checked Baggage?
Checked baggage is any luggage that you hand over to the airline at the check-in counter. The airline stores it in the cargo hold of the plane. You do not carry it with you into the cabin. Instead, you pick it up at your destination airport from the baggage claim area.
Checked baggage is different from carry-on luggage. Carry-on bags stay with you and are stored in the overhead bin. Checked baggage usually includes larger bags, suitcases, or equipment that is too big for the cabin.
Why Is It Important to Know the Size Limit?
Understanding the size limit for checked baggage helps you pack the right way. If your bag is too large or too heavy, you may have to pay extra fees. Some passengers are even asked to remove items from their luggage.
Airlines set size and weight limits to ensure safety and efficiency. Large bags take up more space in the cargo area. Overweight bags can cause delays and handling problems.
Knowing the rules in advance lets you plan better and avoid stress at the airport.
Southwest Airlines’ Unique Baggage Policy
Southwest Airlines has one of the most generous checked baggage policies in the industry. Most airlines charge passengers for each checked bag. But Southwest allows you to check two bags for free.
This makes Southwest a favorite choice for travelers with lots of luggage.
Southwest Airlines Checked Baggage Size Limit
Let’s now look at the specific size and weight limits for Southwest checked baggage.
Maximum Size
The total size of each checked bag must not exceed 62 inches (157 centimeters). This measurement includes the length, width, and height of the bag. It is called the linear dimension.
To calculate this, measure:
- The length of the bag (longest side)
- The width of the bag (shortest side)
- The height (from top to bottom)
Add all three numbers together. If the total is 62 inches or less, your bag meets the size requirement.
For example, if your suitcase measures:
- Length: 28 inches
- Width: 18 inches
- Height: 16 inches
Then the total is 28 + 18 + 16 = 62 inches. This bag is okay to check in with Southwest.
Maximum Weight
Each checked bag must not weigh more than 50 pounds (23 kilograms).
If your bag weighs more than 50 pounds but less than 100 pounds, Southwest will accept it as overweight baggage, but you will have to pay an extra fee.
If the bag weighs more than 100 pounds, Southwest will not accept it as checked baggage.
Summary Table
| Feature | Limit |
|---|---|
| Size Limit | 62 linear inches (157 cm) |
| Weight Limit | 50 pounds (23 kg) |
| Overweight Bag | 51-100 pounds (extra fee applies) |
| Oversized Bag | Over 62 inches (extra fee applies) |
| Bag over 100 lbs | Not accepted |
What Happens If You Exceed the Size or Weight Limit?
If your checked bag exceeds the size or weight limits, you may have to pay:
- $75 per item for an overweight bag (51-100 lbs)
- $75 per item for an oversized bag (63-80 linear inches)
These fees are added to your ticket and must be paid at the airport check-in counter. The fees are per bag and per direction (so you pay again on the return flight).
If your bag is both oversized and overweight, the $75 fee is charged twice (total of $150 per bag).
Items That May Cause Oversize or Overweight Baggage
Here are common items that can push your bag over the limits:
- Large boots and heavy shoes
- Thick winter coats or jackets
- Sports gear like helmets or skates
- Books, especially hardcover books
- Gym equipment like weights or dumbbells
- Large amounts of toiletries
Always weigh your bag at home using a luggage scale. You can also measure its size with a tape measure.
Tips to Stay Within the Checked Baggage Size Limit
Staying within the size and weight limits is easier than you might think. Here are some practical tips:
Use Lightweight Luggage
Choose a suitcase made of lightweight materials. This gives you more room to pack items without exceeding the weight limit.
Don’t Overpack
Only bring what you need. Make a packing list and avoid packing “just in case” items. Travel-size toiletries also help save weight.
Roll Your Clothes
Rolling your clothes takes up less space than folding. This method also reduces wrinkles and gives you more room.
Wear Heavy Items
If you’re bringing heavy boots or jackets, wear them during the flight instead of packing them.
Use Packing Cubes
Packing cubes organize your items and help distribute weight evenly. They also make it easier to repack.
Special Checked Items
Southwest Airlines allows special items like sports equipment and musical instruments. Some of these items count as one of your two free checked bags. Others may require an additional fee.
Sports Equipment
Allowed items include:
- Golf clubs
- Snowboards
- Skis
- Surfboards (within the U.S. only)
Check the Southwest website for the latest rules on packaging and fees.
Musical Instruments
If your musical instrument fits within the size limit, you can check it as baggage. If it’s valuable or fragile, consider carrying it on the plane.
Traveling with Infants or Children
If you are traveling with a baby or child, Southwest allows extra items like:
- Car seats
- Strollers
- Diaper bags
These items can be checked for free, in addition to your two free bags.
What to Expect at the Airport
When you arrive at the airport, go to the Southwest Airlines check-in counter or use a self-service kiosk. Print your bag tags and attach them to your luggage.
Then take your bags to the baggage drop counter. A Southwest employee will weigh and measure your bags. If everything is within the limit, your bags will be checked for free.
If your bag is too big or too heavy, you will be asked to pay a fee. You may also be asked to move items to another bag or your carry-on.
Baggage Tracking and Claiming
After your flight, go to the baggage claim area at your destination airport. Look for the screen that shows your flight number and carousel number.
If your bag is delayed or lost, go to the Southwest Airlines Baggage Service Office near the baggage claim area. You can also file a claim online.
Checked Baggage Rules for International Travel
Southwest mainly flies within the United States, but it also has international routes. If you’re flying to Mexico, the Caribbean, or Central America, the same checked baggage rules apply.
However, always double-check the rules when booking international flights, as customs rules may affect what you can pack.
What Is Not Allowed in Checked Baggage?
Even though checked baggage goes in the cargo hold, certain items are still banned for safety reasons. These include:
- Explosives or fireworks
- Flammable liquids
- Lithium batteries (loose)
- Weapons (unless declared and packed properly)
- Perishable food without proper packaging
Always check the TSA and airline websites before packing these items.
Refunds for Baggage Fees
Since Southwest allows two checked bags for free, most travelers do not pay baggage fees. However, if you pay for an extra bag and your flight is canceled or delayed, you can request a refund.
Go to the Southwest Airlines website and follow the instructions under the “Refunds” section.
How Does Southwest Compare with Other Airlines?
Here is a comparison of baggage fees for some U.S. airlines:
| Airline | Free Checked Bags | Baggage Fee (1st Bag) | Baggage Fee (2nd Bag) |
| Southwest Airlines | 2 | $0 | $0 |
| Delta Air Lines | 0 | $35 | $45 |
| American Airlines | 0 | $35 | $45 |
| United Airlines | 0 | $35 | $45 |
As you can see, Southwest’s baggage policy is more generous than most other airlines. If you travel often or with lots of luggage, this can save you a lot of money over time.
Conclusion
