What is allowed in carry-on baggage Southwest airlines size?
When flying with Southwest Airlines, understanding the full scope of the Southwest carry on size, the carry on items allowed on Southwest, and the overall Southwest carry on policy can help travelers avoid unexpected fees, delays, or last-minute bag checks at the gate. Whether you’re a frequent flyer or a first-time traveler, it’s essential to pack smartly by following Southwest carry on rules and updated TSA regulations.
What Is Considered a Carry-On Bag on Southwest Airlines?
Southwest Airlines allows every passenger to bring one carry-on bag and one personal item for free. A carry-on bag refers to luggage that fits in the overhead bin and adheres to size guidelines, while a personal item includes backpacks, briefcases, laptop bags, or purses that fit under the seat in front of you.
Southwest Airlines Carry-On Size and Weight Limits
The official Southwest Airlines carry on size must not exceed 24 x 16 x 10 inches (including handles and wheels). This includes small suitcases, duffel bags, and roller bags. While Southwest does not explicitly state a Southwest carry on weight limit, bags must be light enough for passengers to lift into the overhead compartment without assistance.
Travelers often ask, “Does Southwest allow carry-on?” Yes, and even better — it’s included with your ticket. There are no extra fees unless the bag exceeds size restrictions or must be checked at the gate.
Personal Item Guidelines: What Counts and What Doesn’t
The Southwest airlines personal item size limit is smaller than the carry-on: the item must fit underneath the seat in front of you. Common examples include small backpacks, shoulder bags, and laptop cases. A carry on and personal item are both allowed, but exceeding this may result in gate-checking or fees.
Southwest Carry-On Items Allowed: What You Can Bring
The list of carry on items allowed on Southwest includes:
- Laptops and electronics
- Books and reading materials
- Food in containers (TSA-approved)
- Baby formula, breast pumps, and diaper bags
- Medical equipment and prescriptions
- Jackets, umbrellas, and duty-free items
These Southwest carry on items are safe to travel with, provided they meet TSA and airline size requirements. Items such as toiletries must comply with the Southwest carry on liquids rule (TSA’s 3-1-1 guideline).
Carry-On Restrictions Southwest Flyers Must Know
There are strict carry on restrictions Southwest passengers must adhere to:
- No liquids over 3.4 oz unless medically necessary
- Sharp items like scissors or knives are prohibited
- Flammable items and aerosols are restricted
- Firearms are not allowed in carry-on luggage (check Southwest’s firearms policy for checked baggage)
Understanding the baggage policy for Southwest is crucial to avoid delays and repacking at the gate.
Southwest Carry-On Liquids: TSA 3-1-1 Rule
Southwest follows TSA guidelines. Each passenger may carry liquids in 3.4-ounce containers or smaller, all packed into a single quart-sized, resealable plastic bag. This includes:
- Shampoo and conditioner
- Toothpaste
- Lotions and sunscreens
- Liquid medications (with prescription, if required)
Failure to follow the Southwest carry on liquids policy may result in items being confiscated at security.
Southwest Carry-On Duffel Bag: Is It Allowed?
Yes, a Southwest carry on duffel bag is acceptable as long as it fits within the 24 x 16 x 10 inch size limit. Many travelers prefer soft-sided duffels for flexibility when storing bags in overhead compartments.
Can You Bring a Backpack and a Carry-On on Southwest?
Yes. Southwest permits one carry-on and one personal item per passenger. A backpack can count as either depending on its size. If it fits under the seat, it qualifies as a personal item. If it’s too large, it must meet the Southwest carry on dimensions.
Checked Bag Policy and Weight Limit
Southwest remains the only major U.S. airline to offer two free checked bags per passenger. Each checked bag must not exceed 50 pounds in weight and 62 inches in total dimensions. The checked bag weight limit Southwest enforces is strict, and exceeding it can incur overweight baggage fees.
Knowing the baggage limits Southwest sets for both carry-ons and checked bags will help avoid surprises at check-in.
Packing Tips to Maximize Your Carry-On Space
- Use packing cubes for better organization
- Wear bulkier clothing like jackets and boots
- Utilize your personal item efficiently by storing tech and essentials
- Avoid liquids when possible; buy toiletries after security
These strategies will help you stay compliant with Southwest carry on guidelines while maximizing your packing capacity.
By understanding the full Southwest carry on policy, including dimensions, permitted items, and Southwest carry on rules, you can ensure a smooth and fee-free travel experience. Whether you bring a duffel, backpack, or small roller bag, knowing the rules lets you focus on your flight—not your luggage.
