For the 2026 travel season, Southwest Airlines generally requires children aged 2 and older to pay the full adult fare. Unlike some international carriers that offer a "child discount" (usually 10-25% off), U.S. domestic airlines, including Southwest, have largely standardized their pricing so that any child occupying a seat pays the same "Wanna Get Away," "Anytime," or "Business Select" price as an adult. The only exception is for Lap Children (infants under the age of 2), who can fly for free on domestic flights if they sit on an adult's lap. If you want a guaranteed seat for your infant, you must purchase a ticket at the full fare. Southwest does occasionally offer "Infant Fares" for children under 2 on certain routes, but these are often more expensive than the discounted "Wanna Get Away" adult fares, so they are rarely used. It is also worth noting that Southwest provides Family Boarding between groups A and B for those traveling with children ages 6 or younger, ensuring families can find seats together even without paying for an upgraded boarding position.
