Ryanair has criticized Fraport for not passing on a 75% reduction in airport modernization fees to airlines and passengers, accusing it of being a monopoly that prioritizes profits over competitiveness. Ryanair plans to close its Thessaloniki base due to a 66% increase in airport charges by Fraport. The airline urges the Greek government to intervene and break Fraport's monopoly to enhance competition in Greek aviation. Fraport, in response, defends its practices and attributes Ryanair's service reduction to its own business strategy.
