International airport serving Castellón, located approximately 30 km north of Castellón de la Plana city, near the municipalities of Villanueva de Alcolea and Benlloch. Its identification codes are IATA: CDT and OACI: LECH.

The project originated in the mid-1990s as a personal initiative of Carlos Fabra, then president of the Provincial Council of Castellón, who conceived it as a key component to boost tourism in the province. Construction lasted several years with a total cost of approximately 176 million euros. It was officially inaugurated in March 2011, but took more than two years to receive its first commercial civil flight.

Its location is notably rural: situated approximately 15 km in a straight line from the nearest town of significance, in an area with irregular terrain and unfavourable wind conditions, factors that increased both its construction and operational costs. This location, far from any major city, distinguishes it from most Spanish airports of reference.

The airport was managed successively by the public company Aerocas, the Canadian company SNC-Lavalin and the French company Edeis Management, before returning to Aerocas control. For years it became a symbol of the excesses of the Spanish property bubble: before operating its first flight, it already had a statue of Carlos Fabra on its premises. In 2013, a capital deficit of more than 61 million euros was detected in Aerocas, and that same year Fabra stepped down as president of the company when oral proceedings were opened against him for bribery, influence trafficking and tax offences.
