Traveling with a baby can feel overwhelming, especially when you’re unsure about airline rules. If you’re flying with Southwest Airlines, understanding their infant policy can make your journey smooth and stress-free. This complete guide explains everything you need to know about the Southwest Airlines Infant Policy, including lap child rules, ticketing options, baggage allowances, stroller policies, and safety requirements. Whether you’re planning your baby’s first flight or traveling frequently with infants, this guide will help you prepare with confidence and avoid last-minute surprises at the airport.

What is Southwest Airlines Infant Policy? 

The Southwest Airlines Infant Policy allows parents or guardians to travel with infants under the age of two years safely and conveniently. Infants can either travel as a lap child (sitting on an adult’s lap) or in a separate seat with an approved child restraint system. One of the biggest advantages of flying with Southwest Airlines is that they do not charge a base fare for lap infants on domestic flights, making it a budget-friendly choice for families.

However, proper documentation is required, including proof of age such as a birth certificate or passport. The airline also allows essential baby items like strollers and car seats to be checked free of charge. For international travel, additional taxes and fees may apply even for lap infants.

Southwest focuses on flexibility and family-friendly services, offering pre-boarding options for families with young children. This ensures parents get extra time to settle in before takeoff. Overall, the infant policy is designed to make flying easier, safer, and more comfortable for both parents and babies.

How Does It Work?

Traveling with an infant on Southwest Airlines is simple if you follow these steps:

• Step 1: Decide whether your infant will travel as a lap child or in a separate seat
• Step 2: Add the infant during booking or contact customer service to include them in your reservation
• Step 3: Carry valid proof of age (birth certificate or passport)
• Step 4: Arrive early at the airport for document verification
• Step 5: Take advantage of family pre-boarding to settle comfortably

If you choose a separate seat, ensure your child uses an FAA-approved car seat for safety during the flight.
