In 2024, Leonor moved on to naval training in Galicia. She boarded Spain’s famous training ship, Juan Sebastián de Elcano, for a demanding 140-day journey covering 17,000 miles.
During the voyage, she worked as a crew member. The ship crossed the Atlantic Ocean, travelled around South America, and reached New York. She later served aboard the warship Blas de Lezo before returning to Cadiz in July.
In December 2025, Leonor made history again. She completed her first solo flight in a Pilatus PC-21 aircraft, becoming the first female member of the Spanish royal family to achieve this milestone.
