Southwest Carry on Size Limits [2022 Update]

When it comes to affordability and customer-friendly policies, Southwest Airlines reins. With a generous change and baggage policy, it is hard to find another airline that comes close. Passengers love Southwest’s flexibility and generous carry-on allowance that comes standard with even the lowest priced fares. There will be no nickel and diming when you fly Southwest, although they are known for the cheapest fares around. 

As part of every fare, all passengers are allowed to bring one bag and one personal item. If you are traveling with a pet, that will count as either your carry-on or personal item. Examples of personal items include a purse, jacket, small backpack, briefcase, laptop, etc. All personal items must be small enough to fit beneath the seat in front of you (16.25” (L) + 13.5” (W) + 8” (H) ).

FAQ

What if my Carry-On Needs to be Checked at the Gate?

In the event you are unable to bring your baggage on board, it will be safely stowed below the plane. Once you arrive at your destination, you may pick your items up at baggage claim. If you are bringing a stroller or other assistive device, the airline staff will properly store it and have it available for you at the gate or jet bridge upon landing.  If your bag needs to be checked, you must remove the following:

  • Medication
  • E-cigarettes
  • Spare batteries
  • Assistive devices (i.e., canes, etc.)
  • Keys

How Much Liquid Can I Carry on Board? 

According to the Southwest Airline website, each passenger is allowed to pack one quart-sized bag of liquids, aerosol, gels, creams, and pastes in their carryon bag. These are limited to 3.4 oz (100 mL) or less per item. During TSA security screening, these items must be removed from your carryon for inspection (unless you have been selected for TSA PreCheck expedited screening, in which case you may be exempt from the screening process). Any liquid, aerosol, gel, cream, or paste that triggers an alarm during screening will require additional screening. Medications and infant and child nourishments are exempt from the 3.4 oz limit.

Are Batteries, e-cigarettes, or Lighters Allowed on the Plane? 

Passengers are allowed to carry up to 20 spare batteries at a time. This includes all chargers for mobile phones, tablets, and laptops. These items may not be checked in. E-Cigarettes are also allowed only for carry-on but may not be used on board. Passengers may carry one lighter.
