Flying with Southwest Airlines: Everything You Need to Know About Carry-On Rules
When it comes to air travel, packing your carry-on properly can be the difference between a smooth experience and an airport headache. Thankfully, Southwest Carry On is known for its traveler-friendly policies—especially in the baggage department.
If you’re planning to fly with Southwest and want to make sure you’re packing within the rules, this blog will guide you through everything you need to know about carry-on luggage—from allowed items and size limits to smart packing tips.
What Can You Bring on Board?
Southwest Airlines allows each passenger to bring the following items free of charge:
- One carry-on bag
- One personal item
This generous policy applies to all travelers, regardless of fare type. Whether you’re flying on a Business Select or Wanna Get Away fare, you’re entitled to bring both items into the cabin at no extra cost.
Carry-On Size Limits
To ensure your carry-on fits in the overhead bin, Southwest has specific size guidelines. The maximum dimensions allowed for a carry-on bag are:
- 24 inches (length)
- 16 inches (width)
- 10 inches (height)
These dimensions include wheels and handles, so it’s important to measure your bag before heading to the airport. Bags that exceed these limits may need to be checked at the gate.
Personal Item Guidelines
A personal item must be small enough to fit under the seat in front of you. Acceptable personal items include:
- Small backpack
- Purse or handbag
- Laptop bag
- Briefcase
While the airline doesn’t list exact dimensions for personal items, the key is that they shouldn’t block the aisle or your legroom. Always aim for compact and practical.
Is There a Carry-On Weight Limit?
One of the best features of Southwest’s policy is that there is no official weight limit for carry-on bags. That means you won’t be asked to weigh your bag during check-in or boarding—as long as it fits in the overhead bin and you can lift it yourself without assistance, it’s acceptable.
This is especially helpful for travelers carrying heavy electronics, books, or camera gear. However, if a bag appears too large or heavy, gate agents have the right to ask that it be checked.
What’s Not Allowed in a Carry-On?
Despite the flexibility in size and weight, passengers must still follow standard TSA safety regulations. You cannot bring the following items in your carry-on:
- Liquids over 3.4 ounces (unless they meet exemption criteria)
- Weapons or sharp objects
- Aerosols or flammable substances
- Large sporting equipment
- Tools or items that could be considered dangerous
All items must pass through airport security screening before entering the cabin.
Smart Tips for Packing Your Carry-On
- Stick to soft-sided luggage – It’s easier to fit into tight bins.
- Use packing cubes or organizers – Keeps items tidy and maximizes space.
- Wear bulky clothing on the plane – Save space in your bag by wearing jackets or boots.
- Keep essentials in your personal item – Medications, ID, chargers, and snacks should be within reach.
- Double-check dimensions – Even a small overage can lead to your bag being checked at the gate.
Why Travelers Appreciate Southwest’s Carry-On Policy
In an age where many airlines are charging fees for even a small bag, Southwest maintains a refreshing approach. Their carry-on policy is consistent, generous, and easy to understand. You don’t have to worry about surprise fees, weight checks, or confusing terms—it’s straightforward and customer-focused.
This makes Southwest a favorite among both leisure and business travelers who prefer to keep their belongings with them during the flight.
Final Thoughts
Flying with Southwest Airlines offers travelers peace of mind, especially when it comes to baggage. With no hidden fees for carry-ons, flexible weight allowances, and a traveler-first attitude, Southwest continues to set the standard for stress-free packing and flying.
