5 Key Facts About Southwest Carry-On Policy

Travelling Light and Smart: 5 Key Facts About Southwest Carry-On Policy

Southwest Airlines has always been famous for its people-first way, and although some of their baggage policies have recently undergone changes (most notably for checked bags), their Southwest carry-on policy is still very liberal. Familiarising yourself with these rules can make your flying experience a great deal easier, preventing you from getting caught out at the last minute and allowing you to enjoy a worry-free flight. If you're inquiring about Southwest Airlines baggage policies for your cabin luggage, the following five key facts are worth remembering.

1. "One Plus One" Rule: Carry-On and Personal Item

Southwest permits all passengers to carry one carry-on bag and one personal item. This "one plus one" policy is typical at many airlines, but Southwest's sizes are very generous. Your primary carry-on bag is meant to go in the overhead bin, while your personal item will go under the seat ahead of you. This leaves you with plenty of room to stash items within easy reach on your flight.

2. Southwest Airlines Carry-On Size Limit: What Fits in the Overhead?

The maximum dimensions for your main carry-on bag on Southwest are 24 inches (L) x 16 inches (W) x 10 inches (H). It's crucial to remember that these dimensions include any wheels, handles, and external attachments. A good rule of thumb is to measure your bag thoroughly before heading to the airport. Although Southwest doesn't have an exact weight requirement for carry-on bags, you need to be able to lift your bag into the overhead bin by yourself. If your bag is larger than these Southwest Airlines carry-on size limit guidelines, you may be asked to gate-check, which, based on your ticket type, may cost you (especially if you've already checked your two free bags).

3. Southwest Personal Item Size: Under the Seat Essentials

In addition to your primary carry-on, you also have the ability to bring a Southwest personal item size bag. This item will need to be small enough to fit entirely under the seat in front of you. Common examples are a purse, briefcase, laptop bag, small backpack, or a camera bag. The standard size for a personal item is 18.5 inches (L) x 13.5 inches (W) x 8.5 inches (H). This permit is ideal for having your most critical items, such as documents, gadgets, snacks, or a book, within convenient reach while aboard your flight.

4. No Weight Limit (For Carry-On, Anyway!)

One of the most impressive aspects of Southwest's Southwest cabin bag policy is that there is no designated weight restriction on carry-ons and personal items. Although you'll still want to be able to lift your carry-on up into the overhead bin, this is a huge bonus in comparison to some other airlines which have strict weight limits for cabin bags. It's always best to pack sensibly though to prevent discomfort or struggling with your bags.

5. What is Extra? Special Items and Exemptions

In addition to your typical carry-on and personal item, some items are not included in your Southwest baggage limits and can be taken on board as well. These tend to be:

Assistive aids (such as wheelchairs, canes, crutches)

Outerwear (coats, wraps)

Food for on-board consumption (in disposable containers)

Child safety systems (for an accompanying ticketed child or if room is available)

Medical equipment (such as CPAP machines)

Umbrellas or walking canes

Conclusion

It's always best to consult Southwest's official page to find out the latest and most complete list of approved extra items, particularly if you have special travel requirements. Pet carriers, for instance, are allowed in the cabin but can be considered either your personal item or carry-on and need an extra charge.
