“The decision by AENA and its shareholders (including the Spanish Government) to increase already uncompetitive airport charges by 6.62 per cent next year is the latest evidence that the monopolistic airport operator has no interest in developing traffic at Spain’s regional airports, and simply wants to focus on making record profits from the country’s main airports,” Eddie Wilson, CEO of Ryanair DAC, the main operating airline of the group, said in a press release.
