Online Checkin for Child and Infant Fares
If your child is traveling on an Infant or Child Fare and is age verified, you may request his/her boarding pass on southwest.com. If your child is traveling on an Infant or Child Fare and is not age verified, you must provide valid proof of age at the airport when exchanging the confirmation number for a boarding pass. Your child will not be able to check in online.
- Age Verification Process:
- If your child is traveling on an Infant or Child Fare and does not have a Rapid Rewards or Southwest account, you must create one for him/her in order to check in online.
- You must present a valid Government-issued I.D. providing age (child) or a birth certificate (infant) to the Customer Service Agent at the airport when you check in for your flight. At that time, the date of birth listed in your child's account will be updated to indicate that age has been verified.
- If you prefer, you may mail a copy of the child's valid Government-issued I.D. proving age (for children) or the birth certificate (infants) to: Southwest Airlines Customer Relations; PO Box 36662; Dallas, TX 75235. Be sure to include your child's Rapid Rewards or Southwest account number with your request and submit it at least two weeks prior to your child's flight.
- The date of birth field in your child's account will be updated to reflect that he/she is age-verified. Please allow two weeks for processing.
- If you submit your request in writing, you will receive a confirmation letter in the mail once the date of birth has been verified.
- Once the date of birth has been verified, you may check in online and request a boarding pass as long as your child's account number is present in the reservation for which you are checking in.
- Please remember to provide your child's Rapid Rewards or Southwest account number when you make future reservations on southwest.com or with a Southwest Airlines Customer Representative over the phone so that you can check in online.
If you are not traveling on a Infant, Child, or Senior Fare, you do not need to be age verified to request your boarding pass on southwest.com or at an Self-Service kiosk.
