Does Southwest Airlines Allow Two Carry-On Bags per Passenger?



Stepping into the boarding line with two bags in hand only to be stopped by a gate agent can instantly sour your travel mood. For passengers flying southwest baggage regulations, the question of carry-on allowances is crucial, especially given their unique open-seating policy. The answer isn't a simple yes or no; it hinges on a critical distinction between bag types and strict adherence to size. Misunderstanding this can mean a last-minute, stressful gate-check or an unexpected fee.


What Is Southwest’s Two-Item Policy for Carry-On vs. Personal Item?


Southwest Airlines stands out with a passenger-friendly baggage policy that includes two free checked bags. But their cabin allowance is equally generous, following a common industry standard with a specific twist. Yes, Southwest allows each passenger to bring two items into the cabin, but they must fit into defined categories:

  • One Carry-On Bag: This is your standard overhead bin item, like a rolling suitcase or a large duffel bag.

  • One Personal Item: This is a smaller bag that must fit under the seat in front of you, such as a laptop bag, purse, or small backpack.

This is the core of the southwest baggage regulations. Your "second bag" is not another roller suitcase; it is a distinctly smaller personal item. Attempting to bring two full-sized suitcases into the cabin will result in one being checked at the gate.


What Are the Critical Details About Size and Fit?


Knowing you can bring two items is only half the battle. The other half is ensuring they meet the precise southwest baggage specifications. Southwest is strict about dimensions to ensure smooth boarding and sufficient space for all passengers.

  • Carry-On Size Limit: Your overhead bag must not exceed 24 inches long x 16 inches wide x 10 inches high (including handles and wheels). This is the official southwest air carry on luggage size. Bags that are visibly overstuffed or exceed these dimensions may be flagged.

  • Personal Item Size: While Southwest doesn't publish exact dimensions for personal items, a reliable guideline is 18.5 inches long x 8.5 inches wide x 13.5 inches high. It must stow completely under the seat without blocking your legroom or the aisle.

  • Pro Tip: Use the sizing bins often located near the gate. If your carry-on fits easily into the bin, you’re cleared for the overhead. Your personal item should slide under a seat with room to spare.


How This Policy Impacts Your Travel Strategy?


Understanding these southwest baggage regulations allows for smart packing. Savvy travelers use the personal item not just for a purse, but to maximize their free carry-on capacity. A compliant backpack can hold a significant amount—laptops, snacks, a change of clothes, and important medications—leaving more room in your main carry-on.

However, this policy also means boarding order matters. As a late boarding group (like C), you risk the overhead bins being full. In this scenario, even a compliant carry-on may be gate-checked for free, while your personal item stays with you. This is why many frequent Southwest flyers value EarlyBird Check-In® or aim for an A-group boarding position.


Conclusion


Southwest Airlines does permit two carry-on items per passenger, but within a clearly defined framework. The distinction between a full-sized carry-on and a smaller personal item is non-negotiable. Your success in bringing both aboard hinges entirely on your adherence to the published southwest air carry on luggage size and your judgment of what constitutes a true personal item. By packing with these southwest baggage specifications in mind and understanding how boarding works, you can confidently approach your flight with two bags, avoiding last-minute gate drama and starting your journey smoothly.
