When a baby is born during a flight, the immediate priority is the medical safety of the mother and infant. Cabin crew are trained in basic first aid, including childbirth, and will immediately call for any medical professionals on board while coordinating with ground-based doctors via "MedLink." The captain may choose to divert the aircraft to the nearest suitable airport if there are complications. Regarding the baby's citizenship, the rules vary by country. If the birth occurs in U.S. airspace, the child usually receives U.S. citizenship under the principle of jus soli. However, many countries follow jus sanguinis, where the baby inherits the parents' citizenship regardless of location. Some international laws also allow the child to take the citizenship of the country where the aircraft is registered. As for the "free flights for life" myth, while a few airlines like Thai Airways or Polar Airlines have occasionally granted such perks for publicity, it is not a standard industry rule. Most airlines simply provide a celebratory atmosphere, and the "place of birth" on the birth certificate is typically recorded as the coordinates of the aircraft at the time of delivery or the city of the next landing.
