Bilbao airport is one of the most outstanding expressions of the renewal and new strength of the city of Bilbao. It is located 12 kilometres from the Biscay capital, in the municipality of Loiu.

Bilbao airport has effectively dealt with a constant increase in traffic over recent years, traffic which is mainly domestic. In order to improve the airport's operational capacity, increase passenger service quality, allow passengers to wait sheltered from the elements and to improve communications between strategic points of the airport, a refurbished, enclosed and air-conditioned arrivals hall entered into service in 2011, as did eight new lifts and two connecting ramps between the arrivals floor and the gallery, which connects with the car park.

In 2018, 5,469,453 passengers passed through its facilities, 49,966 flights operated and 1,216 tonnes of cargo were transported.
