Ferronats, a joint venture between Spanish infrastructure firm Ferrovial and UK air navigation service provider NATS, has won a contract to manage 10 control towers in Spain.
The Spanish government earlier this year said it planned to privatise air traffic control at 13 airports across the country.
Ferronats has won its bid to manage air traffic control at the following airports: Alicante, Cuatro Vientos, Ibiza, Jerez, La Coruña, Melilla, Sabadell, Seville, Valencia and Vigo.
Air traffic control contracts at the remaining three airports - Fuerteventura, Lanzarote and La Palma - have been awarded to Saerco, an arm of Spanish construction firm Acciona.
The contracts are for five years with an option to extend by another 12 months.
The annual cost of the service will be €18.1 million ($24.6 million), down from the €33.9 million that Spanish airport operator AENA is currently spending.
