Southwest Airlines Carry-On Baggage: The Ultimate Guide for Stress-Free Travel

When it comes to air travel, packing efficiently is a key part of ensuring your trip goes smoothly. Southwest Airlines, known for its generous baggage policies and customer-friendly services, makes traveling with a carry-on simple and straightforward. But like all airlines, Southwest has specific rules about carry-on baggage that you’ll need to be aware of. Whether you're flying for business or pleasure, understanding these guidelines will save you time and avoid frustration at the airport.

In this blog, we’ll cover everything you need to know about Southwest Airlines’ carry-on baggage policy—from size restrictions to helpful packing tips!

1. Southwest Carry-On Baggage Rules: What You Can Bring Onboard

Southwest Airlines allows every passenger to bring one carry-on bag and one personal item for free. These two items should fit within specific size limits, but there are no weight restrictions for carry-on bags. Here’s a breakdown of what’s allowed:

• Carry-On Bag: Your carry-on bag must fit in the overhead bin, and it should not exceed the following dimensions:

  • 10 inches x 16 inches x 24 inches (25 cm x 40 cm x 61 cm).

  While Southwest doesn’t have a weight limit for carry-ons, your bag should be light enough for you to lift and place in the overhead compartment.

• Personal Item: A personal item is a smaller bag that fits under the seat in front of you. Examples include a purse, backpack, laptop bag, briefcase, or small diaper bag. The maximum dimensions for a personal item are:

  • 18.5 inches x 8.5 inches x 13.5 inches (47 cm x 22 cm x 34 cm).

2. What to Pack in Your Carry-On for a Comfortable Flight

Packing your carry-on efficiently is essential, especially if you want to have everything you need within easy reach. Here are some essential items you should consider packing in your carry-on bag:

• Travel Essentials: Always keep your ID, boarding pass, passport (if applicable), and any other important documents easily accessible.
• Medications: If you need medication during your flight, pack it in your carry-on, along with any necessary prescriptions. Remember to keep them in their original containers to avoid any issues at security.
• Electronics: For entertainment and productivity, don’t forget your phone, tablet, laptop, or e-reader, along with their chargers and headphones.
• Snacks & Drinks: Pack snacks that are easy to eat in-flight—granola bars, nuts, or fruit are great choices. While you can’t bring a large bottle of liquid through security, you can fill up a reusable water bottle once you’ve passed through the checkpoint.
• Toiletries: Follow TSA guidelines for liquids and gels in carry-on bags—limit them to 3.4 ounces (100 mL) or less and store them in a quart-sized zip-top bag.

3. Prohibited Items in Southwest Carry-On Baggage

To ensure a safe and comfortable flight, Southwest Airlines follows TSA guidelines regarding restricted items. Here’s a list of items you cannot bring in your carry-on:

• Sharp objects: Knives, scissors, and other sharp items that could potentially harm others are not allowed.
• Large liquids and gels: Anything exceeding 3.4 ounces (100 mL) must be placed in your checked luggage.
• Firearms and weapons: Firearms and other dangerous weapons are strictly prohibited from the cabin.
• Explosives or flammable materials: Fireworks, flammable liquids, and other hazardous items are banned from both carry-on and checked luggage.

4. What to Do if Your Carry-On Bag Doesn’t Fit

If your carry-on bag is too large to fit in the overhead bin, Southwest may ask you to check it. However, Southwest Airlines is one of the few airlines that offers two free checked bags per passenger. So, even if you have to check your carry-on, you won’t incur an additional fee.

To avoid this scenario, ensure your carry-on bag complies with the size limits before you arrive at the airport. Most airports have bag sizers located near the check-in counter or gate, so you can double-check if your bag fits the requirements.

5. Maximizing Your Carry-On Space: Packing Tips

To make the most of your carry-on allowance, packing smart is crucial. Here are some tips to help you fit everything you need without overstuffing your bag:

• Roll Your Clothes: Rolling your clothes instead of folding them can save space and minimize wrinkles.
• Use Packing Cubes: These small, zippered organizers help compress your clothing and make it easier to find items.
• Wear Bulkier Items: If you’re bringing a jacket, sweater, or heavier shoes, wear them on the plane to save space in your bag.
• Limit Shoes: Shoes are bulky and take up a lot of room. Try to bring no more than two pairs—one for travel and one for any activities during your trip.

6. Additional Considerations for Southwest Passengers

Southwest Airlines has a number of perks that make it easier for passengers to travel with carry-on luggage:

• Family Boarding: If you’re traveling with young children, Southwest offers Family Boarding, allowing you to board before general boarding. This can give you a head start in securing space for your carry-on in the overhead bins.
• Southwest’s Open Seating Policy: Southwest Airlines doesn’t assign seats in advance, so it’s a good idea to check in early and secure your preferred seat. This open seating policy also means the overhead bins fill up quickly, so be sure to board early to ensure you get space for your carry-on.

7. Carry-On Baggage Fees: Are There Any?

The best part about flying with Southwest is that they don’t charge a fee for carry-on baggage. Unlike many other airlines that charge extra for carry-on bags, Southwest lets you bring one carry-on and one personal item for free. This makes Southwest a great choice for travelers who want to avoid hidden fees and keep things simple.
