Carryon Baggage

Federal regulations limit each Customer to one bag and one small personal item.

Your carryon

  • Carryon bag dimensions are limited to
    10 x 16 x 24 inches.
  • You must store your carryon in the overhead bin. Storing it wheels facing out helps us get wheels up faster!
  • If you're traveling with a pet, carriers are counted as either your personal item or carryon.
  • A friendly reminder: If your carryon does not fit the dimensions above, we will be forced to check it at the gate. It will be safely stowed below the aircraft for the duration of your flight, and you will pick it up at baggage claim, not the gate, upon arrival to your final destination. Assistive devices and strollers may be claimed at the gate/jet bridge.
  • Ouch!: Please make sure that any sharp objects (especially needles, syringes, and other items needed for medication) are properly covered and secured to prevent injury to yourself and our Employees who care for your bags.
  • Please alert a Flight Attendant if you use a needle/syringe while onboard so we may provide you with access to a disposal container

Your personal item

  • Personal-type items include purses, briefcases, cameras, food containers, or laptops (case included).
  • Your personal item must be stored under
    the seat in front of you.
  • A friendly reminder: If your personal item does not fit under your seat, you will be asked to place it in an overhead bin.

The following items are not considered carryon bags or personal-type items and are not counted against the "one-bag plus one personal-type item" limit:

  • A child restraint device for a ticketed child with a reserved seat or when complimentary, available space exists.
  • Assistive/mobility devices for individuals with a disability. There is no limit to the number of assistive/mobility devices a Customer can bring onboard the aircraft.
  • Outer garments or other wearable articles of clothing.
  • Food for consumption during flight contained in disposable packaging.
  • Walking canes or umbrellas.
  • Liquids, aerosol, gels, creams and pastes

    Each passenger is permitted to bring one quart-sized bag of liquids aerosol, gels, creams and pastes in your carryon bag and through the TSA security checkpoint. These are limited to 3.4 ounces (100 milliliters) or less per item. During screening, you'll be required to place these items in the small bag separate from your carryon baggage unless you have been selected for TSA PreCheck expedited screening, in which case you may be exempt from removing your liquids during the screening process.

    • Any liquid, aerosol, gel, cream or paste that alarms during screening will require additional screening.
    • Certain items are exempt from the TSA carryon liquid rules including medications and infant and child nourishments.

    Southwest Airlines currently prohibits self-defense sprays on any flight regardless if it is checked or carried on. Please see the TSA's web site for a list of prohibited carryon items.

  • Lithium batteries, e-cigarettes, and lighters

    Passengers are allowed to travel with up to 20 spare batteries at a time. This includes portable chargers and external battery chargers for mobile phones, tablets, and laptops. Portable charges and spare batteries must be packed in your carryon bag or be with you onboard.

    Because e-cigarettes are designed to operate by creating heat, they must be placed in a carryon bag or be with you onboard. A friendly reminder, e-cigarettes cannot be used onboard our aircraft.

    Passengers are also allowed to travel with one lighter, which must be in your carryon or with you onboard.

  • Strollers and Child Restraint Systems (CRSs)
    or car seats

    Customers traveling with children will be allowed to check one stroller and one Child Restraint System (CRS) or car seat per child without charge. This is in addition to the regular free baggage allowance.

    The stroller and CRS or car seat allowance applies to any type of stroller (umbrella, full size, jogging stroller, etc.) and CRS or car seat.

    The Customer may check the stroller and CRS or car seat at the curb, ticket counter, or gate. Southwest Airlines will not assume liability for damage to strollers, CRS’s or car seats.

    An optional Southwest-branded reusable car seat/stroller bag is available for purchase at any Southwest Airlines ticket counter for a $17 onetime fee. Bag dimensions are 42”X20.5X12.5”.

  • International travel

    Duty-free items: Passengers traveling internationally into the United States with a connecting flight will be permitted to carry liquids in excess of 3.4 oz or 100 mL in their carryon baggage, provided they were purchased in duty-free shops and placed in secure, tamper-evident bags (STEBs).

    Technological advances may allow passengers to keep these liquids in their carryon baggage, provided they are presented in a STEB and are able to be screened and cleared by Transportation Security Officers at the checkpoint.

    Liquids that cannot be screened and cleared will not be allowed to remain in a passenger’s carry-on baggage. Passengers may elect to place these items into checked baggage, if available, or forfeit them prior to entering the secure area of the airport. This may include liquids in opaque, ceramic, or metallic bottles, or other containers that cannot be effectively scanned.
