Feb 17, 2025

When planning a trip with Southwest Airlines, understanding their "carry-on size policy" is essential for a smooth travel experience. Knowing the dimensions allowed for a carry-on can save you from unexpected fees and hassles at the airport. Below, we will explain Southwest Airlines' carry-on policy, provide a detailed chart, and highlight important points for travelers.

Southwest Airlines Carry-On Policy Overview

Southwest Airlines allows passengers to bring one "carry-on bag" and one personal item on board for free. This is especially advantageous for travelers looking to avoid checked baggage fees. The carry-on bag must adhere to specific size restrictions, ensuring it can fit in the overhead bin or under the seat in front of you.

Allowed Dimensions for Carry-On Luggage

The size restrictions for carry-on luggage with Southwest Airlines are clearly defined. Here’s a quick reference chart outlining the maximum dimensions:

Item	Maximum Dimensions
Carry-On Bag	10 x 16 x 24 inches (including wheels and handles)
Personal Item	Up to 18.5 x 8.5 x 13.5 inches

It’s important to note that the "carry-on bag" must fit within these dimensions, which include wheels and handles. If your bag exceeds the size limit, Southwest Airlines may require you to check it in, potentially incurring additional fees.

Examples of Acceptable Carry-On Items

Standard suitcase or duffel bag
Backpack
Rolling suitcase
Computer bag or briefcase

Your "personal item" can also take various forms, such as:

Purse
Small backpack
Laptop bag
Camera bag

Both the carry-on and personal items should be easy to handle and should not pose a risk of blocking aisles or emergency exits.

Additional Carry-On Policy Considerations

While Southwest Airlines has a straightforward "carry-on policy", there are a few additional considerations to keep in mind:

1. Weight Restrictions

Unlike some airlines, Southwest Airlines does not impose a weight limit on carry-on bags. However, you must be able to lift your bag into the overhead bin without assistance.

2. Prohibited Items

Be sure to familiarize yourself with the Transportation Security Administration (TSA) regulations for what items are prohibited in carry-on luggage. This includes items like sharp objects, liquids over 3.4 ounces, and flammable materials.

3. Security Screening

When going through security, all carry-on items must be screened. Ensure that your personal item is easily accessible as you will need to remove it from your bag during screening.

4. Connecting Flights

If you have connecting flights, make sure to check if the carry-on policy is consistent throughout your journey, especially if you are flying with partner airlines.

Tips for Packing Your Carry-On

To make the most of your carry-on luggage, consider these packing tips:

Roll your clothes to save space and minimize wrinkles.
Use packing cubes to organize items.
Pack versatile clothing that can be mixed and matched.
Keep essential items like medications and travel documents in an easily accessible pocket.

By following these tips, you can maximize your carry-on space and ensure you have everything you need within reach during your flight.

Conclusion

Understanding Southwest Airlines' "carry-on size policy" is crucial for a hassle-free travel experience. With a generous allowance for free carry-on bags and personal items, you can easily navigate your journey without incurring extra fees. Always check the dimensions before you pack and stay informed about prohibited items to ensure a smooth check-in and boarding process. Happy travels!
