The Spanish government has unveiled an investment plan that will allocate €12.9 billion to the expansion of the country’s airport capacity during the period 2027-2031. The details of this project will be included in an official plan called “Documento de Regulación Aeroportuaria” (DORA III) which assesses the investment needs for the entire Spanish airport system on a five-year basis. Other major investments will be made in expanding the capacity of airport terminals in areas that see a significant volume of tourism-related traffic. The two airports on the island of Tenerife, Tenerife Norte (TFN) and Tenerife Sur–Reina Sofia (TFS), will receive €550 million and €250 million, respectively. Airport investment in Spain is typically funded by landing fees and other charges paid by operators.
