The Airborne citizenship can be defined as the birthright citizenship for children born on plane or carrier. While it is normal for the new born baby to inherit the citizenship of parents, it is also possible for the child to acquire supplemental “airplane” citizenship, based on the airspace owned by the state.

Being born on an airplane is a rare occurrence, and the child is often referred to as a "Sky-born" baby or an "Aerial infant." From a legal perspective, the term "Jus soli" (Right of the Soil) and "Jus sanguinis" (Right of Blood) are the governing principles for the child's citizenship. If a baby is born in the airspace of a country that recognizes jus soli (like the United States), the child may be eligible for citizenship of that country, even if the parents are not citizens. However, if the birth occurs over the high seas or in the airspace of a country that only recognizes jus sanguinis, the child typically inherits the citizenship of the parents. Additionally, the 1961 Convention on the Reduction of Statelessness states that a birth on a ship or aircraft is considered to have occurred in the country where the vehicle is registered. In 2026, while many airlines have policies discouraging travel after 36 weeks to avoid this "logistical miracle," some airlines are known to grant "Sky-born" babies free flights for life, though this is more of a marketing myth than a standard industry rule.
