These airports are shaping the future of international travel, proving that the post-pandemic surge is not a temporary blip but a sustainable trend.

Athens International Airport: Greece’s Star Performer in 2025

Athens International Airport is leading the charge for Greece’s tourism boom. By November 2025, AIA had welcomed over 31.68 million passengers, marking an impressive 6.6% year-on-year growth. This surge in traffic is a direct reflection of Greece’s increasing appeal as a global travel destination, particularly in the wake of pandemic-related slowdowns. AIA’s performance has surpassed previous records, and with year-end projections estimating a final tally of over 33.5 million passengers, Greece is cementing its place as one of Europe’s must-visit spots.

This growth has been fueled by the introduction of new international routes, particularly to North America, Asia, and Europe. AIA is increasingly serving as a gateway for tourists flocking to Athens, the Greek islands, and the mainland. The rise in off-season visitors has further extended Greece’s tourism season, signaling a shift in global travel patterns. The airport’s contribution to the country’s economic recovery is significant, as local businesses in hospitality, retail, and tourism benefit from the rising numbers of international visitors.

With improved connectivity and a steadily increasing number of non-stop international services, Denver is poised to remain a key hub for travelers looking to access the United States and beyond.
