This comprehensive guide will walk you through everything you need to know about Southwest Airlines' carry-on allowance, ensuring a smooth and stress-free journey. Let's dive in!
Navigating Southwest Airlines Carry-On Policies: Your Ultimate Guide
When it comes to carry-on baggage, Southwest Airlines has a straightforward policy, but understanding the nuances is key. Unlike some airlines that might confuse you with various fare types impacting your allowance, Southwest keeps it consistent for all passengers.
Step 1: Understand the Basics of Southwest's Carry-On Policy
Alright, let's kick things off! Before you even think about packing, the absolute first thing you need to grasp is Southwest's fundamental rule:
You are allowed ONE carry-on bag AND ONE personal item.
That's right, it's a simple 1+1 rule. No tricks, no hidden clauses (mostly!). This means you get a bag for the overhead bin and a smaller item to tuck under the seat in front of you.
Why is this important? Knowing this upfront prevents overpacking and potential gate-checking fees, which can quickly add up!
Step 2: Mastering the Dimensions: Size Matters!
Now that you know how many bags you get, let's talk about the crucial part: their size. Ignoring these dimensions is a surefire way to run into trouble at the airport!
Sub-heading: Your Carry-On Bag (Overhead Bin)
Your main carry-on bag is designed to fit in the overhead compartment. It needs to adhere to specific measurements:
Maximum Dimensions: 24 inches (L) x 16 inches (W) x 10 inches (H).
Important Note: These dimensions include wheels, handles, and any external attachments. Don't just measure the main body of your suitcase; extendable handles and bulky wheels can push you over the limit.
Examples: This typically includes standard roller bags, small suitcases, or a duffel bag that can be compressed.
Sub-heading: Your Personal Item (Under the Seat)
Your personal item is smaller and designed to fit comfortably under the seat in front of you, ensuring easy access during your flight.
Maximum Dimensions: 18.5 inches (L) x 8.5 inches (W) x 13.5 inches (H).
Examples: Common personal items include:
Purses (including crossbody bags)
Briefcases
Laptop computer cases
Small backpacks
A pillow or blanket (neck pillows do not count towards the carry-on limit)
A small camera bag
Pro Tip: Always try to fit your personal item under the seat before stowing your carry-on in the overhead. This helps ensure everyone has space for their larger bags.
Step 3: Understanding What DOESN'T Count Towards Your Limit
Southwest is quite accommodating with certain items that don't count against your one carry-on and one personal item allowance. This is where you can be smart about what you bring!
Outer Garments: This includes coats, jackets, wraps, or shawls.
Food for Consumption During Flight: As long as it's in disposable packaging. So, pack that sandwich and snacks!
Assistive/Mobility Devices: This is a big one! Items like wheelchairs, crutches, canes, walkers, and personal oxygen concentrators (POCs) are allowed in addition to your carry-on and personal item.
Child Restraint Systems/Car Seats: If you've purchased a ticket for your child, an FAA-approved child restraint system can be carried on and will not count towards your limit. Even if you haven't purchased a ticket for your child but there's a complimentary, available space, you may bring a child restraint.
Diaper Bags: When traveling with an infant or small child, a diaper bag is usually permitted in addition to your allowance.
Medical Equipment: Necessary medical devices and medications.
Umbrellas/Walking Canes: These are generally allowed in addition.
Crucial Advice: While these items generally don't count, it's always a good idea to confirm with Southwest directly or check their official website for the most up-to-date information, especially for specialized medical equipment. Policies can sometimes change.
Step 4: Packing Smart: Liquids, Prohibited Items, and Special Circumstances
Now that you know what you can bring and how many, let's talk about what's inside your bags and some specific scenarios.
Sub-heading: Liquids in Your Carry-On (The TSA 3-1-1 Rule)
Southwest, like all airlines operating in the US, adheres to TSA (Transportation Security Administration) regulations for liquids, aerosols, gels, creams, and pastes in carry-on baggage. This is known as the 3-1-1 rule:
3.4 ounces (100 milliliters) or less per container.
All containers must fit in one (1) quart-sized, clear, plastic, zip-top bag.
One (1) such bag per passenger.
Remember: This rule applies to everything from toothpaste and shampoo to hand sanitizer and certain food items. Larger liquid containers must go in your checked baggage.
Sub-heading: Prohibited Items You Absolutely Cannot Carry On
This is critical for a smooth security experience. Never attempt to carry on:
Flammable Liquids and Solids: Lighter fluid, paints, fireworks, etc.
Explosives: Any type of explosive device.
Compressed Gases: Including camping stoves with gas canisters.
Corrosives and Poisons: Bleach, drain cleaners, etc.
Firearms and Ammunition: Unless properly declared and transported as checked baggage according to strict regulations.
Sharp Objects (with restrictions): While small nail clippers are okay, larger scissors (blades over 4 inches), box cutters, and certain knives are not allowed in carry-on.
Self-Defense Items: Mace, pepper spray, stun guns are generally prohibited.
Hoverboards/Self-Balancing Boards: Due to lithium battery fire concerns, these are strictly prohibited in both carry-on and checked baggage.
When in doubt, check the TSA website or Southwest's official hazardous materials list! A quick search can save you a lot of hassle.
Sub-heading: Traveling with Pets
If you're bringing your furry friend, remember that a pet carrier counts as either your personal item or your carry-on bag. It doesn't get a separate allowance. There's also a fee for bringing a pet in the cabin.
Sub-heading: Musical Instruments
Musical instruments can be a bit tricky. Small instruments (like violins) that fit the carry-on dimensions can be brought onboard. Larger instruments that exceed the carry-on size may still be carried on if they fit in an overhead bin or under a seat and space is available when you board. For very large instruments (e.g., a cello), you might need to purchase an additional seat for it. Always check Southwest's specific policy for musical instruments if you're traveling with one.
Step 5: What Happens If Your Carry-On is Too Big or Too Many?
Despite all your careful planning, sometimes things happen. Here's what you can expect:
At the Gate: If your carry-on bag exceeds the dimensions or if the flight is full and overhead bin space is limited, you might be asked to gate-check your bag. Southwest generally does not charge for gate-checked bags that are within the checked baggage allowance (two free checked bags), but it can be an inconvenience.
Over-sized/Over-weight Checked Bags: If your bag needs to be checked and it exceeds Southwest's generous free checked baggage allowance (two bags up to 50 lbs and 62 linear inches each), you will incur fees for overweight or oversized bags. These fees can be substantial, so it's always better to ensure your bags are within limits before you get to the airport.
Step 6: Boarding and Stowing Your Bags
Southwest's open seating policy means boarding groups are crucial for securing overhead bin space.
Early Boarding = More Overhead Space: If you have an A-group boarding pass or pay for EarlyBird Check-In, you'll generally board earlier, giving you a better chance to find space directly above your seat.
Later Boarding = Less Space: If you're in the B or C group, overhead space might be limited, and you may need to find space further down the aisle or be asked to gate-check your bag.
Stowing Your Bags Properly: Ensure your carry-on fits entirely in the overhead bin (wheels first for roller bags usually works best). Your personal item should be tucked completely under the seat in front of you. This is for safety and to keep the aisles clear.
By following these steps, you'll be a pro at navigating Southwest's carry-on policies and enjoy a much smoother travel experience!
