At Southwest Airlines, each passenger can have one carry-on bag and one personal item upon boarding the plane. A personal item is usually smaller than the carry-on piece, and would constitute a purse, camera or laptop, while the carry-on luggage would be a bag that is no larger than 10 by 16 by 24 inches in size. Carry-on items are susceptible to being searched by the airline, whether they belong to customers or employees.
Some items important to traveling customers do not count toward their carry-on and personal item limits. These items include child restraints for the plane, strollers or car seats. People can also freely bring on walking sticks, jackets and some types of personal mobile devices without counting them as carry-on pieces.
Passengers are not permitted to carry on any kind of personal defense spray, nor can they check this kind of product.
Southwest Airlines does not charge fees for the first two checked bags, encouraging customers to check rather than carry-on their luggage. Although they have liberal bag policies, they strictly abide by Transportation Security Administration policy about liquids, which must be in bottles 3.4 ounces or under when carried on. Baggage checked with the airline cannot weigh more than 50 lbs., or be larger than 62 inches.
