18 February 2026 (Geneva/Madrid) – The International Air Transport Association (IATA) and the Spanish Airline Association (ALA) called for an annual reduction of 4.9% (excluding inflation) in Spanish airport charges over the next five years (2027-2031), a level compatible with maintaining an airport investment plan of nearly €10 billion over the same period, and enhancing Spain’s economic competitiveness.
AENA, the operator of most airports in Spain, has proposed an annual increase of 3.8% (excluding inflation) for the five-year period covered by the Third Airport Regulation Document (DORA III). Airlines reject this proposal, citing AENA’s consistent underestimation of traffic growth and the excessive regulated returns it has earned during previous regulatory periods.
Between 2017 and 2025, excluding the two pandemic years, actual passenger traffic was on average 15.3% higher than the forecasts set out in DORA I and DORA II. This gap between forecasts and actual figures resulted in AENA earning €1.3 billion in excess regulated returns, costs that were ultimately borne by airlines and consumers. In the most recent year for which published data is available, AENA’s regulated return in 2024 reached 10.2%—four percentage points above its expected return—meaning that nearly €400 million was overpaid by airlines and passengers in that year alone.
“AENA has gamed the regulatory system for years, earning millions of euros more than it should have, at the expense of passengers, airlines, and the Spanish economy. This must stop.
AENA has generated excessive returns through a creative approach to forecasting, and its request for further increases is absurd. If granted, it would deliver the highest regulated return of any comparable airport operator in Europe. This is unsustainable and unrealistic—we need to see a reduction in charges,” said Rafael Schvartzman, IATA’s Regional Vice President for Europe.
Importantly, the reduction in charges proposed by IATA and ALA would not prevent AENA from delivering its planned €10 billion investment program during DORA III. According to separate studies commissioned from global consultancies Steer and CEPA, passenger traffic will grow by around 3.6% per year on average, compared with AENA’s forecast of just 1.3% annually. Under these assumptions, AENA would still be able to fully fund its investment plan while earning a return on capital of 6.35%—a more generous return than it was intended to earn under DORA II.
“Our proposal for a 4.9% cut in charges will improve Spain’s competitiveness as an international destination, stimulating investment and job creation across the wider economy. At the same time, AENA can still afford its €10 billion investment plan and deliver reasonable returns to its shareholders. This is a win-win for passengers, Spain, and the aviation industry. We look forward to regulators reviewing the evidence and reaching the right conclusions,” Schvartzman added.
