Carry-On Weight and Other Carry-On Items You Can Bring

In addition to size, Southwest Airlines has weight limitations for carry-on bags. While there isn’t a specific weight requirement, the bag should be light enough to easily lift and store in the overhead bin without assistance. As a general rule, most passengers can carry up to two bags on board: one carry-on and one personal item like a briefcase, purse, or laptop bag. If you’re bringing extra items, such as a camera, food container, or even clothing in disposable packaging for consumption, make sure they fit within your personal item limits. Special considerations apply for assistive mobility devices or child-restraint seats, which are typically reserved in advance.

What Can I Bring On Board Southwest Airlines Flights?

If you’re traveling with a pet, Southwest allows you to bring them on board in a carrier that fits under the seat in front of you. Each pet carrier must meet specific carrier size guidelines and must conform to the carry-on limits, meaning it counts as your personal item. Only one pet is allowed per flight on a first-come, first-served basis, so it’s a good idea to book early. Keep in mind, pets are accepted only if you’re a paying customer with a ticket, and you’ll be charged an additional pet fee each way. If your pet is too large for the carry-on, you may need to check them in a separate checked carrier, but this will depend on the airline’s availability at the airport.

 

Note: When flying with Southwest, if your itinerary includes international flights, you can bring your pets on board, but they must travel in-cabin in a pet carrier that fits under the seat in front of you. Pets are permitted for travel within the U.S. and some international destinations. However, make sure to check the airline’s policies for international travel as each country may have different requirements for pets. As with domestic flights, your pet will need to stay in a carrier that conforms to the carry-on size limits, and you will be charged an additional pet fee.

Human Remains

When you need to transport human remains with Southwest, there are specific conditions to follow. Cremated remains can be carried onboard or as checked luggage on domestic or international flights. These remains should be placed in a temporary plastic or cardboard container that meets security requirements. You must contact the airline in advance to ensure that your shipment will meet all requirements. Keep in mind that there may be extra time needed at the airport for the security check. Cremated remains are subject to specific guidelines and are treated differently from pet remains, so it’s essential to confirm all details with the airline before travelling.

Medical Assisted Devices

Southwest Airlines allows passengers to bring medically necessary devices onboard, including items like needles, syringes, walkers, canes, crutches, and CPAP machines. These medical devices can be transported in the cabin and do not count as part of your regular carry-on or personal item. To ensure safety and prevent injury, these items must be secured properly. It’s important to check the airline’s policy for any specific guidelines regarding their transport. If you need to bring such devices, it’s always a good idea to inform Southwest employees in advance, ensuring your devices are permitted and meet all necessary requirements.

Battery-Powered Mobility Aids

If you’re traveling with a battery-powered mobility aid, such as a wheelchair or other mobility aids, Southwest Airlines allows these devices to be brought into the cabin with certain conditions. The device must be permitted for transport and properly packed to prevent damage. It should be turned off during the flight, with the key or on/off switch in the off position, and any joystick should be disconnected. Additionally, the batteries must have their terminals isolated, and clear labels in English should be visible to indicate there are no defects or damage. Always check the specific airline policy for mobility aids to ensure your device meets all the requirements.

Other items

When packing for your Southwest Airlines flight, be sure to follow the rules for other items that you may want to bring along. Children’s strollers and musical instruments in cases can be brought as carry-on bags or personal items, but they must fit in overhead bins or under seats. Certain items, like camcorders, media cameras, and even e-cigarettes or vaping devices, are allowed in the cabin, but must be kept in compliance with FAA safety regulations. Items like perishable items should be wrapped and packed in heavy plastic or styrofoam cartons. If they exceed the carry-on bag sizes, they may need to be stowed in checked luggage. Skateboards, parachutes, and hazardous items like safety matches or a common lighter are not permitted onboard, so always check the guidelines before packing

Flammable liquids, such as gasoline, kerosene, and even lighter fluid, are also not allowed. Other items that are restricted include sharp objects like knives, razors, cutting instruments, ice picks, and metal scissors, as well as camping equipment and hoverboards. If you’re unsure about whether an item is permitted, it’s always recommended to check the TSA website or contact Southwest before packing.

For liquids, there are strict liquid restrictions, with beverages and alcohol only permitted in containers that do not exceed 3.4 ounces (100 millilitres).

Remember to check Southwest’s website for any updated guidelines on what can and cannot be carried onboard.

Choosing the Right Carry-on Bag for You

Choosing the right carry-on bag depends on your needs and how much you plan to pack. For a day trip, a small backpack may be all you need, while for longer trips, a weekender or duffel bag can hold more items like clothing and essentials. If you prefer easy mobility, a wheeled luggage option is a great choice. It’s important to choose a bag that fits within Southwest’s size and restrictions to avoid issues at the gate. Whether you’re flying for business or leisure, choosing a Travelpro bag that’s designed to meet these guidelines will give you the confidence to travel without worrying about fitting your bag. If you’re traveling for a longer trip, consider a larger bag that will easily accommodate everything you’ll need to arrive at your destination and unpack with ease.
