Dongdo International Airport

Dongdo International Airport (Zhenian: 동도국제공항, Dongdo Gukje Gonghang), (DOD, ZHDD) is an  situated on an artificial island in the middle of 1.7 kilometers away from the southwestern coast of Seondo Island, part of the Haedong Archipelago in Zhenia. It is the primary air gateway into Dongdo and the Haedong Islands as a whole, situated 14 kilometers away from downtown Dongdo. It is situated adjacent to the Dongdo Seaplane Port, which offers seaplane flights to less accessible islands throughout the Haedong Islands, although it is operated separately from the airport itself.

Dongdo International Airport was built to permanently replace the Suyeong Airport during the Third Republic, which was clearly showing its limitations amid the rapid expansion of Dongdo's urban areas. With the Haedong Islands being overall mountainous in terrain, it had been decided by 1578 that a replacement airport would be built on reclaimed land, only that it would be situated on an artificial island off the coast of the island to minimize impact to the city's growth. With the airport itself opening by 1593, it today consists of two terminals - Terminals 1 and 2 - each dedicated to certain airline alliances and types of airlines respectively.

Despite having a vast majority of its flights geared towards domestic and regional flights in East Tarsis, it remains the sixth-busiest airport in the nation by passenger traffic, mostly fueled by Dongdo's immense demand for tourism. The Daedo-Dongdo route, which terminates at the airport, is the second-busiest flight route in the nation, second only to the Daedo-Jinhae route. Aside from domestic flights within Zhenia, it offers hundreds of weekly flights to other nations in East Tarsis, including Sakaro, Yinguo and Ayeran.
