Investor Analysis of Greek Airport Traffic 2026 for late March confirms a robust 9.1% Q1 surge, led by a 13.1% February spike at Athens International (AIA). While Fraport Greece celebrates an 81.4% load factor and the completion of RRF runway upgrades at Mykonos and Santorini, a critical "reliability gap" persists. High-density routes like Athens–Dubai face a 36.07% disruption rate, challenging the sector’s transition to a year-round institutional model.
