Yes, Southwest Airlines is unique among major carriers for allowing both a carry-on bag and a personal item for free for every passenger.
Planning a trip often involves a careful dance of budgeting and packing, and understanding an airline’s baggage policy is a significant step in that process. Southwest Airlines distinguishes itself from many other airlines with a policy that can simplify your travel preparations and help you avoid unexpected fees at the airport.
Southwest’s Generous Carry-On Policy Explained
Southwest Airlines consistently offers a refreshing approach to baggage, differentiating itself by including a carry-on bag and a personal item for every fare-paying passenger without any additional cost. This policy applies across all fare types, from the most basic to the most flexible, ensuring a consistent experience for all travelers.
This inclusion means you can bring a small suitcase or duffel bag into the cabin, along with a smaller item like a purse, laptop bag, or backpack. This approach contrasts with many other airlines that have introduced fees for carry-on bags, especially on their basic economy fares, or that limit passengers to only a personal item.
Carry-On Bag Dimensions and Weight
To ensure your carry-on fits comfortably in the overhead bin, Southwest specifies maximum dimensions. Your carry-on bag should not exceed 24 inches in length, 16 inches in width, and 10 inches in height (24L x 16W x 10H inches). These measurements include wheels and handles, so it’s wise to measure your bag accurately before heading to the airport.
A notable advantage with Southwest is the absence of a weight limit for carry-on bags. As long as the bag fits within the stated dimensions and you can lift it into the overhead bin unassisted, you are generally good to go. This flexibility is a welcome relief for travelers who pack heavier items that still fit within the size constraints.
Personal Item Guidelines
In addition to your main carry-on, you are permitted one personal item. This item must fit underneath the seat in front of you. The maximum dimensions for a personal item are 18.5 inches in length, 8.5 inches in width, and 13.5 inches in height (18.5L x 8.5W x 13.5H inches).
Common examples of personal items include a purse, a briefcase, a laptop bag, a small backpack, or a camera bag. Items like coats, umbrellas, and approved child safety seats are generally not counted against your personal item allowance.
Navigating the Overhead Bins and Under-Seat Space
Southwest’s open seating policy means that boarding position plays a role in overhead bin availability. Passengers with earlier boarding positions (A group, or those who purchase Upgraded Boarding or EarlyBird Check-In) typically have more choices for stowing their carry-on bags.
Once you board, place your carry-on bag in an overhead bin with the wheels facing inward for optimal space utilization. Your personal item should go under the seat directly in front of you, ensuring easy access during the flight and a clear aisle.
What Belongs in Your Carry-On? Essential Packing Tips
Deciding what to pack in your carry-on versus a checked bag requires careful thought, especially for items you cannot afford to lose or that are restricted in checked luggage. Always keep essential medications, essential documents, valuables, and electronics with you in the cabin.
Liquids, aerosols, gels, creams, and pastes in carry-on bags are subject to the TSA 3-1-1 rule. Each item must be 3.4 ounces (100 milliliters) or less per container, fit in one quart-sized bag, and be limited to one bag per passenger. This rule helps streamline security screening for everyone.
Medications and Medical Devices
All prescription and over-the-counter medications, whether liquid or pill form, should travel with you in your carry-on. This ensures you have immediate access to them and prevents issues if checked luggage is delayed or misplaced. Medically necessary liquids, such as insulin or other essential liquid medications, are exempt from the 3-1-1 rule but must be declared to TSA officers for inspection.
Medical devices, like CPAP machines, can generally be brought on board as an additional item beyond your carry-on and personal item, provided they fit under the seat or in the overhead bin. Always verify specific requirements with the airline and TSA for specialized medical equipment.
Electronics and Power Banks
Laptops, tablets, cameras, and other valuable electronics are best kept in your carry-on to protect them from potential damage or theft. For security screening, be prepared to remove larger electronic devices from your bag and place them in a separate bin.
Lithium-ion power banks and spare lithium batteries must always be stored in your carry-on bag and are strictly prohibited in checked luggage due to fire safety concerns. This regulation is a critical safety measure for all air travel.
| Carry-On Bag | Personal Item |
|---|---|
| Small Suitcase (24x16x10 inches max) | Laptop Bag (18.5×8.5×13.5 inches max) |
| Duffel Bag (within dimensions) | Purse or Small Shoulder Bag |
| Small Backpack (within dimensions) | Briefcase or Document Holder |
| Overnight Bag | Camera Bag (compact) |
Checked Bags: Another Free Perk with Southwest
Beyond the generous carry-on policy, Southwest Airlines offers another substantial benefit: two free checked bags for every passenger. This policy significantly reduces the stress and cost associated with traveling, especially for longer trips or those requiring more gear.
Each checked bag can weigh up to 50 pounds (23 kg) and have a maximum linear dimension (length + width + height) of 62 inches. Exceeding these limits for weight or size will incur additional fees, so it’s always prudent to weigh and measure your bags before arriving at the airport.
This free checked bag allowance can be particularly useful for items that are not permitted in carry-ons, such as large liquids, sharp objects, or sporting equipment that fits within the size and weight limits. Utilizing both carry-on and checked bag allowances effectively can make for a more organized and stress-free journey.
| Baggage Type | Allowance | Key Specifications |
|---|---|---|
| Carry-On Bag | One Free | Max 24L x 16W x 10H inches, No Weight Limit |
| Personal Item | One Free | Max 18.5L x 8.5W x 13.5H inches, Fits Under Seat |
| Checked Bags | Two Free | Max 50 lbs (23 kg) each, Max 62 linear inches each |
Special Items and Unique Situations
Southwest accommodates various special items, often as part of the free baggage allowance or as additional items. Musical instruments, for example, can be carried on if they fit in the overhead bin or under the seat, counting as your carry-on item. Larger instruments may need to be checked or have a seat purchased for them.
Child restraint systems (car seats) and strollers can be checked free of charge in addition to the standard baggage allowance. They can also be gate-checked, meaning you can use them up to the boarding gate and then have them loaded into the cargo hold. When bringing a child safety seat on board, it must be FAA approved for air travel and fit in the aircraft seat.
Assistive devices for passengers with disabilities, such as wheelchairs, crutches, or walkers, are also transported free of charge and do not count against the carry-on or checked baggage limits. It’s always a good practice to notify Southwest in advance if you are traveling with specialized equipment to ensure a smooth process.
Smart Packing Strategies for a Smooth Journey
Maximizing your carry-on space while adhering to airline rules is an art form. Rolling clothes tightly can save significant space compared to folding. Utilizing packing cubes helps compress items and organize different categories of clothing, making it easier to find what you need without unpacking everything.
Consider wearing your bulkiest items, like heavy jackets or boots, rather than packing them. This frees up valuable space and weight in your bags. Layering clothing items allows for versatility in varying climates and reduces the need for multiple heavy garments.
When packing your personal item, think about what you’ll need during the flight itself. This includes entertainment, snacks, a water bottle (empty through security, fill after), and any comfort items like a neck pillow or eye mask. Having these easily accessible under the seat makes for a more comfortable flight experience.
Preparing for security checks by placing liquids in an accessible clear bag and having electronics ready for removal will expedite your passage through the screening area. A well-organized bag makes the entire travel process less stressful and more efficient.
