Southwest Airlines Carry-on Baggage Allowance

Before diving into portable charger specifics, let's review Southwest's general carry-on baggage allowance. Understanding the overall size and weight limits sets the stage for properly packing your electronics.

• Size: Southwest allows one carry-on bag per passenger, with maximum dimensions of 24 inches x 16 inches x 10 inches (61 linear inches). This includes handles and wheels.
• Weight: While Southwest doesn't explicitly state a weight limit for carry-on bags, it's crucial to pack light. An overly heavy bag can become difficult to manage and might be subject to gate checking if it's deemed too cumbersome for overhead storage.
• Personal Item: In addition to your carry-on bag, you can bring one personal item, such as a purse, briefcase, or small backpack, that fits under the seat in front of you. This should typically measure no larger than 18.5" x 13.5" x 8".
• Exceptions: Passengers with disabilities or special needs may be allowed additional carry-on items. Contact Southwest directly to discuss your specific requirements.

Portable Chargers and Power Banks: Specific Regulations

Southwest Airlines, like other airlines, has specific regulations regarding portable chargers and power banks due to safety concerns. Understanding these rules is paramount to avoiding issues at security checkpoints.

• Allowed Battery Capacity: Southwest allows portable chargers and power banks with a maximum battery capacity of 100 watt-hours (Wh). This is a crucial number to remember.
• Exceeding the Limit: Power banks exceeding 100 Wh are generally prohibited from being carried on board. Attempting to bring a larger power bank may result in confiscation and potential delays.
• Battery Type: Most commonly used lithium-ion batteries are permitted, provided they meet the 100 Wh limit. However, it’s always best to check the specific specifications of your power bank.
• Packaging and Storage: Keep your portable charger in your carry-on bag, not in your checked luggage. This ensures easy access for security screening and prevents any potential damage during transit.
• Security Check Accessibility: It is critical to keep your portable charger easily accessible during security checks. Having it readily available will streamline the process.

What Happens If You Violate the Rules?

Bringing oversized or prohibited portable chargers can lead to several complications:

• Fees: You might incur fees for oversized or overweight baggage. These fees can vary depending on the extent of the violation.
• Delays: Security personnel may need to inspect your items, causing delays in your boarding process.
• Confiscation: In cases of severe violations, your portable charger might be confiscated.
• Alternatives: If you have a power bank exceeding the allowed capacity, consider leaving it at home, shipping it separately, or purchasing a compliant power bank at your destination.

Tips for Packing Portable Chargers for Southwest Flights

Careful planning prevents problems. Here's how to pack your portable chargers correctly for a smooth Southwest flight:

• Protective Case: Use a sturdy, well-labeled case to protect your charger during transit. This adds an extra layer of security and helps to prevent accidental damage.
• Check Watt-Hour Rating: Always verify the watt-hour (Wh) rating of your portable charger before packing. This is usually printed on the device itself or on its packaging.
• Easy Accessibility: Place the charger in an easily accessible part of your carry-on bag, such as a top compartment or dedicated pocket. This expedites security screening.
• Pack Essentials Together: Consider packing other important items you'll need during the flight near your charger in your carry-on bag, to avoid scrambling when you need them.

Staying Updated on Southwest's Baggage Policies

Airline regulations can change, so staying informed is vital:

• Southwest Website: Regularly check the official Southwest Airlines website for the most current baggage policy information.
• Email Alerts: Sign up for email alerts from Southwest to receive notifications of policy updates.
• Official App: Download and use the official Southwest app; often, updates are highlighted there first.
