Understanding Southwest's Free Carry-On Policy

Southwest Air Lines offers a generous carry-on baggage allowance. When flying with Southwest, each passenger is allowed to bring one standard carry-on item and one personal item onboard for free. This rule applies across most ticket types, including economy, comfort plus, first class, and Southwest One.

What Qualifies as a Carry-On Bag on Southwest?

A carry-on bag is generally a small suitcase, duffel, or backpack that fits in the overhead bin. Southwest requires that carry-on items follow specific size guidelines to ensure they can be stored properly.

Acceptable Carry-On Items Include:

• Rolling suitcases

• Duffel bags

• Backpacks

• Small garment bags

Items must not exceed Southwest’s maximum size dimensions. Bags exceeding this may have to be checked, potentially resulting in fees.

What is Considered a Personal Item on Southwest?

Along with your main carry-on, Southwest permits one personal item that fits under the seat in front of you. Examples include:

• Handbags or purses

• Laptop bags

• Briefcases

• Small backpacks

Personal items must be compact and easily stowable under the seat.

Exceptions to the Carry-On Rules

Although the carry-on policy is straightforward, there are a few exceptions and special cases to be aware of:

Basic Economy Fare

Travelers with a Basic Economy ticket are also entitled to one carry-on and one personal item. Unlike some other airlines that restrict this fare type, Southwest still honors its two-item policy.

International Flights

Southwest maintains the same carry-on allowance for international routes. However, some connecting flights operated by partner airlines or smaller aircraft may have different requirements. Always double-check if your itinerary includes code-share segments.

Southwest Connection and Smaller Aircraft

On regional flights operated by Southwest Connection, the overhead bins may be smaller, and standard-sized carry-ons might not fit. In such cases, you may need to gate-check your carry-on at no additional cost.

---

Can You Bring Additional Items for Free?

Yes, Southwest allows certain items in addition to your standard carry-on and personal item, without counting them against your allowance. These include:

• Jackets and coats

• Umbrellas

• Food or snacks for in-flight consumption

• Duty-free purchases

• Approved child safety seats

• Strollers (for families traveling with infants)

These items should be small enough not to interfere with other passengers or block emergency exits.

Tips to Maximize Southwest’s Carry-On Policy

Here’s how you can make the most out of your free baggage allowance:

Choose the Right Bag

Use a compact, lightweight bag that meets Southwest's size standards. Avoid overpacking to prevent needing to gate-check.

Use Packing Cubes

Packing cubes help organize and compress your items, allowing more space for essentials.

Wear Your Bulky Items

If you're flying in colder weather, wear your heavier clothing to free up space in your carry-on.

Combine Personal Items Wisely

A well-designed laptop backpack can double as both your personal item and an extra storage option for clothing or snacks.

What Happens if You Exceed the Carry-On Limit?

If your bag exceeds Southwest’s carry-on size or weight limits, you may be asked to check it. Additional fees might apply, especially if you already have checked baggage.

To avoid this, always:

• Measure your bags before heading to the airport

• Weigh them if you're unsure about weight restrictions

• Review Southwest’s guidelines ahead of time
