The top 10 busiest routes were largely dominated by Asia and the Middle East, showcasing the robust demand for regional travel. Close contenders included Cairo-Jeddah (4.8 million seats), Hong Kong-Taipei (4.6 million seats), and Seoul-Osaka Kansai (4.2 million seats).

Securing the eighth position was the coveted transatlantic link between New York JFK and London Heathrow, with 3.8 million seats. Additionally, other Southeast Asian connections featuring Singapore underscored its status as a regional air hub.

Within the confines of their own borders, domestic routes in Japan and South Korea took center stage. Jeju-Seoul, Hokkaido Chitose-Tokyo Haneda, and Fukuoka-Tokyo Haneda recorded impressive seat numbers, surpassing 10 million each.

As international travel rebounds and regional hubs continue to thrive, the skies appear poised for even greater levels of traffic in the coming year.

As the skies continue to witness a resurgence in international travel and regional hubs flourish, one can't help but reflect on personal journeys undertaken in the year gone by. 

Whether exploring vibrant metropolises or embracing the tranquility of nature, the question lingers: Where have you traveled this year?
