Oecusse Route of the Sandalwood International Airport — Oecussi-Ambeno, Timor-Leste

Oecusse forms a small exclave of Timor-Leste, cut off from the rest of the country and surrounded entirely by Indonesian territory on the island of Timor, a geographic quirk tracing back to colonial-era boundary decisions made when Portugal and the Netherlands divided the island between them centuries ago. The region's airport, carrying the code OEC, takes its name from the historic sandalwood trade that first drew Portuguese merchants to Timor in the sixteenth century, long before the territory became a colony, making the fragrant wood central to Oecusse's identity even today. Because road travel to the rest of Timor-Leste requires crossing Indonesian territory, this single-runway airport plays an outsized role connecting the enclave to the capital, Dili, supporting Oecusse's designation as a special economic zone meant to attract investment to one of the country's more isolated regions. Passenger volumes remain modest, befitting a small territory with limited infrastructure.
