Southwest Airlines Carry-On Baggage Allowance

Southwest Airlines is known for its generous baggage policy, but understanding the specifics of their carry-on allowance is key to avoiding unexpected fees at the gate. Let's break down the details of what you can bring on board.

Size Restrictions: Navigating Southwest's Carry-On Dimensions

Southwest allows one carry-on bag and one personal item per passenger free of charge. However, exceeding the size limits will result in your bag being gate-checked, incurring a fee. Knowing the exact dimensions is crucial.

• Maximum carry-on dimensions: 24" x 16" x 10" (61cm x 41cm x 25cm). This includes wheels and handles.
• Personal item dimensions: There are no specific published size restrictions for personal items, but Southwest suggests that it should fit under the seat in front of you. Think purses, briefcases, or laptop bags. Oversized personal items may also be gate-checked.
• Measure your bag before you go: This is the single most important step! Use a tape measure to ensure your bag complies with Southwest's carry-on size restrictions before you arrive at the airport. This will save you time and money.

Types of Carry-On Bags Allowed: What's Acceptable?

While Southwest doesn't provide an exhaustive list of prohibited bag types, common sense and safety regulations should guide your choices.

• Soft-sided bags: These are generally recommended because they are more flexible and easier to squeeze into overhead compartments.
• Hard-sided bags: While allowed, hard-sided bags must strictly adhere to the size restrictions. Their rigidity can make them difficult to fit if even slightly oversized.
• Unusual shaped bags: Items like musical instruments, sports equipment, or oversized personal items might require pre-approval from Southwest. Check their for more information and potential additional fees.

Southwest Airlines Portable Charger Regulations

Staying connected on the go is important, but it's equally important to understand Southwest's regulations concerning portable chargers to avoid any issues at security.

Allowed Portable Chargers: Safe and Secure Charging Onboard

Southwest allows portable chargers in carry-on baggage, but with conditions:

• Readily accessible: Keep your portable charger easily accessible within your carry-on bag for security checks.
• Original packaging or protective case: The charger should be in its original packaging or a clearly labeled, protective case. This helps prevent accidental activation and potential damage.
• Spare batteries: Do not pack spare lithium batteries separately unless they are securely contained in a protective case designed for battery transport.

Prohibited Items: What to Leave Behind

Certain items related to portable chargers or deemed hazardous are strictly forbidden, whether in checked or carry-on baggage:

• Damaged or recalled portable chargers: Do not bring any chargers showing signs of damage or those that have been recalled by the manufacturer.
• Loose lithium batteries: These must be contained within a device or an approved protective case. Loose batteries are a fire hazard.
• Chargers exceeding specified wattage or mAh ratings: Southwest follows TSA guidelines. Generally, chargers with a capacity exceeding 100 Watt-hours (Wh) are prohibited from carry-on and checked baggage. Check the latest TSA guidelines for the most up-to-date information on lithium-ion battery regulations.
