If you're traveling with an infant or small child, you should know that proper use of a Child Restraint System (CRS) enhances child safety onboard the aircraft.
Southwest Airlines and the Federal Aviation Administration (FAA) strongly recommend that infants and small children weighing less than 40 pounds be secured in an appropriate CRS when traveling by air. Learn more about Southwest's baby on board policy
If you choose to travel with your infant on your lap, you must obtain a Boarding Verification Document (BVD) for the infant so that they can board the aircraft. Be sure to bring a copy of your infant's birth certificate to the airport for age verification. Learn more about age verification.
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.
