Your Ultimate Guide to Southwest Airlines Carry-On Policy: What You Can REALLY Bring!
Hey there, fellow traveler! Are you staring at your luggage, wondering if everything will fit, and more importantly, if Southwest Airlines will let you bring it all on board? You're not alone! The world of airline baggage policies can feel like a labyrinth, but fear not, because we're about to demystify Southwest's carry-on rules for you, step by step. Let's get you ready for a smooth journey!
Step 1: Understand the Basics – It's Simpler Than You Think!
First things first, let's cut to the chase. Southwest Airlines is generally known for its traveler-friendly policies, and that extends to carry-on baggage. Unlike some other airlines that might nickel and dime you for every little thing, Southwest keeps it straightforward.
So, how many carry-ons can you bring on Southwest Airlines?
The answer is: One (1) carry-on bag AND one (1) personal item.
That's right, you get two distinct items to bring into the cabin with you, free of charge! But before you start packing your entire wardrobe, let's dive into the specifics of what each of these means.
What is a Carry-On Bag?
Your carry-on bag is typically the larger of the two items you bring on board. This is the bag that will likely go in the overhead bin above your seat. Think of it as your small suitcase, roller bag, or a larger backpack.
What is a Personal Item?
Your personal item is a smaller bag that must fit under the seat in front of you. This could be a purse, a briefcase, a laptop bag, a small backpack, or even a neck pillow and blanket (though a neck pillow alone doesn't count towards the limit).
Step 2: Know Your Dimensions – Size Matters (A Lot!)
While Southwest is generous with the number of items, they are strict about the dimensions. If your bags exceed these limits, you might be forced to check them, potentially incurring fees or delays. So, grab your measuring tape!
Carry-On Bag Dimensions:
Your carry-on bag (including wheels and handles) should not exceed:
24 inches (L) x 16 inches (W) x 10 inches (H)
This translates to approximately 61 cm x 41 cm x 25 cm.
Pro-Tip: Many carry-on suitcases are designed to meet these general airline requirements, but it's always best to double-check, especially if your bag is older or unusually shaped.
Personal Item Dimensions:
Your personal item is smaller and needs to fit snugly under the seat. Its dimensions should not exceed:
18.5 inches (L) x 8.5 inches (W) x 13.5 inches (H)
This is approximately 47 cm x 22 cm x 34 cm.
Remember: These dimensions are for the maximum size. If your personal item is smaller, that's perfectly fine!
Weight Restrictions: Is There a Carry-On Weight Limit?
Good news! Southwest Airlines generally does not have a specified weight restriction for carry-on items. This is a significant perk compared to many other airlines. However, you must be able to lift your carry-on bag into the overhead bin unassisted. If it's too heavy for you, it's likely too heavy for the flight attendants to comfortably assist with, and you might be asked to check it.
Step 3: Packing Smart – Maximize Your Carry-On Space
Now that you know the limits, let's talk about how to pack efficiently to make the most of your two items.
The Art of the Carry-On:
Roll, Don't Fold: Rolling your clothes can save a surprising amount of space and reduce wrinkles.
Use Packing Cubes: These can compress your clothing and keep your bag organized, making it easier to fit more.
Wear Bulky Items: If you have a heavy jacket or bulky shoes, wear them on the plane rather than packing them.
Prioritize Essentials: Pack items you absolutely cannot do without (medication, important documents, a change of clothes) in your carry-on in case your checked luggage is delayed.
The Power of the Personal Item:
In-Flight Entertainment: Load up your tablet or e-reader with books, movies, and games.
Comfort Essentials: A neck pillow, eye mask, and noise-canceling headphones can make a world of difference.
Snacks and Hydration: Bring an empty reusable water bottle to fill after security, and some snacks to avoid overpriced airport food.
Valuables: Keep your wallet, passport, and any other high-value items with you in your personal item.
Electronics & Chargers: Laptops, phones, and their chargers are best kept in your personal item for easy access and to avoid damage in checked luggage.
Step 4: Special Items and Exceptions
Southwest Airlines understands that some travelers have unique needs. Here's a quick rundown of common special items and how they factor into your carry-on allowance:
Traveling with Children:
Car Seats/Child Restraint Systems (CRSs): If you've purchased a ticket for your child, an FAA-approved car seat/CRS that will be used during the flight does not count toward your carry-on limit. If you plan to check it, Southwest allows one car seat and one stroller per ticketed customer free of charge. However, be aware of recent changes regarding larger strollers, which may now be subject to oversized baggage fees if they exceed standard checked bag dimensions.
Diaper Bags: A diaper bag is generally considered a personal item. If it's your only personal item, it won't be an issue.
Breast Pumps and Cooler Bags: These are typically allowed in addition to your carry-on and personal item, especially for mothers traveling with infants.
Musical Instruments:
Small Instruments: If your instrument (with its case) fits within the standard carry-on dimensions (24" x 16" x 10"), you can bring it as your carry-on item if there's space available.
Larger Instruments: Instruments that don't fit in the overhead bin or under the seat may be carried on if you purchase an additional seat for them. They must fit in the seat, be secured with a seatbelt, and not block any aircraft signage.
Checking Instruments: Musical instruments can also be checked as part of your free checked baggage allowance, but standard oversized or overweight fees may apply if they exceed limits.
Medical Devices & Assistive Aids:
Items like wheelchairs, crutches, canes, oxygen concentrators, and other assistive devices do not count towards your carry-on limit and can be brought on board as needed. Always notify the airline in advance if you require special assistance or are bringing large medical equipment.
Duty-Free Purchases:
Duty-free liquids purchased internationally can be carried in addition to your allowance if they are in a transparent, secure, tamper-evident bag, and you have the original receipt, with the purchase made within 48 hours.
Step 5: Navigating TSA Security with Your Carry-Ons
Even with the right number and size of bags, TSA regulations are paramount.
The 3-1-1 Rule for Liquids, Gels, and Aerosols:
Each passenger is allowed to carry liquids, gels, and aerosols in travel-size containers that are 3.4 ounces (100 milliliters) or less per item.
All these containers must fit into one (1) quart-sized bag (about 1-liter capacity).
Each passenger is limited to one (1) quart-sized bag.
This bag must be removed from your carry-on and placed in a separate bin for screening.
Exceptions: Medications (prescription and over-the-counter) and infant/child nourishments (like formula, breast milk, or juice) are exempt from the 3-1-1 rule and can be carried in larger quantities, though you should declare them to TSA officers.
Prohibited Items:
Be sure to review the TSA's list of prohibited items to avoid any issues at the security checkpoint. Common items you cannot bring in your carry-on include:
Flammable liquids (e.g., lighter fluid)
Explosives (e.g., fireworks)
Sharp objects (e.g., razor blades not in a cartridge, large scissors - check these!)
Guns and firearms (unless properly declared and checked)
Certain self-defense items (e.g., mace, pepper spray)
Always check the official TSA website for the most up-to-date information on prohibited items.
Step 6: Boarding and Overhead Bin Space
Southwest Airlines operates with an open seating policy. This means there are no assigned seats, and boarding is done by groups (A, B, C) and numbers.
Board Early (If Possible): If you have an A group boarding pass, you'll have a better chance of securing overhead bin space directly above your seat.
Be Prepared for Gate-Checking: While Southwest aims for everyone to bring their carry-ons on board, especially on full flights, sometimes gate agents might ask for volunteers to gate-check their carry-on bags due to limited overhead space. If this happens, your bag will be returned to you at baggage claim at your final destination.
Utilize Under-Seat Space: Your personal item always goes under the seat in front of you. This is non-negotiable for takeoff and landing.
Conclusion: Fly with Confidence!
So, to reiterate, with Southwest Airlines, you are permitted to bring one carry-on bag and one personal item free of charge. By understanding the dimensions, packing smart, and being aware of special item policies and TSA rules, you'll be well-prepared for a stress-free travel experience. Enjoy your flight with Southwest!
