Traveling with carry-on luggage can be a game-changer for a smooth and stress-free journey, especially when flying with an airline known for its customer-friendly policies like Southwest. But how many carry-ons are you actually allowed? Let's dive into the details, and trust me, by the end of this guide, you'll be a Southwest carry-on expert!
Unpacking Southwest's Carry-On Policy: Your Essential Guide
Have you ever stood at the gate, nervously eyeing your carry-on, wondering if it's too big, too heavy, or if you've simply packed too much? We've all been there! The good news is, Southwest Airlines has a relatively straightforward and generous carry-on policy. The key is understanding the specifics, and that's exactly what we're here to do.
Step 1: The Golden Rule – One and One!
Let's start with the absolute core of Southwest's carry-on policy. This is where most people get it right, and it's super simple:
You are permitted one (1) carry-on bag. This is your primary bag, the one that typically goes in the overhead bin.
You are also permitted one (1) personal item. This is a smaller item designed to fit under the seat in front of you.
That's it! One carry-on, one personal item. Remember this, and you're already halfway to a seamless boarding experience.
Sub-heading: What Counts as a Carry-On Bag?
Your main carry-on bag is generally a small suitcase, a roller bag, or a duffel bag that meets the specified dimensions. Think of it as your "overhead bin" bag. It's meant to hold the bulk of your essential items for the flight.
Sub-heading: What Counts as a Personal Item?
A personal item is a smaller bag that must fit under the seat in front of you. Common examples include:
A purse (including crossbody bags)
A briefcase
A laptop computer case
A small backpack
A pillow (like a neck pillow, which typically does not count towards your carry-on limit)
A blanket
A small camera bag
Important Note: If you're traveling with a pet, the pet carrier counts as either your personal item or your carry-on bag. It doesn't get a free pass!
Step 2: Mind Your Dimensions – Size Matters!
Knowing how many bags you can bring is only half the battle. The other crucial part is ensuring they fit within Southwest's size limits. Attempting to board with an oversized bag can lead to delays, frustration, and potentially unexpected checked baggage fees at the gate.
Sub-heading: Carry-On Bag Dimensions
For your main carry-on bag, the maximum dimensions are:
24 inches (Length) + 16 inches (Width) + 10 inches (Height)
Remember to include wheels, handles, and any attachments when measuring your bag. Many bags are advertised by their main compartment size, but it's the overall dimensions that matter. A soft-sided bag might be more forgiving, but a rigid suitcase needs to strictly adhere to these measurements.
Sub-heading: Personal Item Dimensions
Your personal item needs to be even smaller to fit comfortably under the seat. The maximum dimensions for a personal item are:
18.5 inches (Length) + 8.5 inches (Width) + 13.5 inches (Height)
Again, measure carefully! An overstuffed personal item can be just as problematic as an oversized carry-on.
Step 3: Weight? What Weight? – Southwest's Unique Approach
This is where Southwest truly stands out from many other airlines, and it's a huge perk for travelers!
Southwest Airlines does NOT have a specified weight restriction for carry-on items.
That's right! While most airlines have a weight limit for carry-ons (often around 15-22 lbs or 7-10 kg), Southwest's policy is much more relaxed. However, there's a practical implication:
You must be able to lift your carry-on bag into the overhead bin yourself. If you can't, you might be asked to check it at the gate. This is for your safety and the efficiency of boarding.
So, while there's no official weight limit, don't overpack to the point where your bag becomes unmanageable.
Step 4: Special Items – Beyond the Basics
Sometimes, your travel needs extend beyond a standard carry-on and personal item. Southwest is generally accommodating with certain special items.
Sub-heading: Medical Devices and Assistive Devices
Items such as wheelchairs, crutches, walkers, and other assistive devices do not count towards your carry-on limit. You can bring these on board in addition to your one carry-on and one personal item. Similarly, necessary medical equipment (like a CPAP machine) can often be carried on without counting against your allowance. It's always wise to inform the airline in advance if you have specialized medical equipment.
Sub-heading: Outer Garments and Food
A coat, jacket, or other outer garment can be carried on in addition to your allowance.
Food for consumption during the flight, in disposable packaging, is also generally permitted in addition to your carry-on and personal item.
Sub-heading: Traveling with Infants and Children
If you purchase a ticket for your child, an FAA-approved child restraint system (car seat) that will be used during the flight will not count towards your carry-on limit.
You can also check one stroller and one car seat/child restraint system free of charge per ticketed customer.
Sub-heading: Musical Instruments
Small musical instruments that fit within the standard carry-on dimensions (24" L x 16" W x 10" H) can be brought on board as your carry-on item, provided there is space.
Larger musical instruments that exceed carry-on sizing requirements can still be carried onboard if they fit in an overhead bin or under a seat and space is available.
For very large instruments that won't fit in the overhead or under the seat (e.g., a cello), you may purchase a separate seat for them. The instrument must fit in the seat, be secured with a seatbelt, and not block any aircraft signage.
Step 5: What Happens If Your Carry-On is Too Big?
Despite your best efforts, sometimes a bag just doesn't quite make the cut. If your carry-on bag exceeds the dimensions or if there's no available overhead bin space, Southwest may require you to gate check your bag.
Gate Checking: This means your bag will be checked at the gate and placed in the cargo hold, similar to a regular checked bag. You'll then pick it up at baggage claim at your destination.
The good news: For Southwest, if your bag needs to be gate-checked due to space limitations, you typically won't be charged a checked baggage fee, as long as it adheres to the standard checked baggage allowance (two free checked bags up to 50 lbs and 62 linear inches). However, if your bag is oversized or overweight beyond even the checked bag limits, additional fees could apply.
To avoid gate-checking and ensure your bag stays with you in the cabin, always adhere to the carry-on dimensions and try to board earlier if you have an "A" boarding position.
Step 6: Smart Packing Strategies for Southwest
Now that you know the rules, here are some pro tips to make the most of your Southwest carry-on allowance:
Choose the Right Luggage: Invest in a carry-on bag that is specifically designed to meet airline carry-on dimensions. Look for bags that clearly state "FAA approved carry-on" or "fits most airline overhead bins."
Maximize Your Personal Item: Your personal item is a powerful tool! Use it for heavier items like books, electronics, and even an extra pair of shoes. This can significantly reduce the weight of your main carry-on.
Wear Your Bulkiest Items: If you're traveling with a heavy jacket or bulky boots, wear them on the plane rather than trying to cram them into your luggage.
Roll, Don't Fold: Rolling your clothes tightly can save a surprising amount of space in your carry-on.
Utilize Packing Cubes: These organizational wonders can compress your clothes and make it easier to fit more into your bag while keeping things tidy.
Liquids Rule: Don't forget the TSA's 3-1-1 rule for liquids in your carry-on: containers must be 3.4 ounces (100 milliliters) or less, fit in one quart-sized bag, and be limited to one bag per passenger.
By following these steps and understanding Southwest's clear guidelines, you'll be well-prepared for a hassle-free journey with your carry-on bags. Enjoy your flight!
