Southwest Airlines hand luggage allowance

Southwest Airlines hand luggage rules

• Southwest publishes its carryon limit in inches (24" length x 16" width x 10" height); the cm values in this record are converted from the published inches.
• "Wheels, handles, and any attachments count toward these dimensions."
• Southwest does not publish maximum dimensions for the personal item - it only states that it must fit under the seat in front of you.
• No weight limit is published for either the carryon bag or the personal item.
• Personal item examples: purse (including crossbody bags), briefcase, laptop case, backpack, pillow, blanket and small camera; neck pillows do not count toward the carryon limit.
• A pet carrier counts as either the carryon bag or the personal item.
• Carry-on and personal item guidelines may differ on partner airlines.
• Oversized items must be checked at the ticket counter before the departure gate.

Liquids

Not stated on the carryon policy page; Southwest directs customers to TSA rules (US TSA 3-1-1: containers of 3.4 oz / 100 ml or less in one quart-size clear bag).

Remember that the liquids rule that applies to you is set by the airport you fly from, not the airline. Check your departure airport before you pack.
