Birjand International Airport (IATA: XBJ, ICAO: OIMB) serves Birjand, the capital of South Khorasan Province in eastern Iran. It provides essential air connectivity for a region that is otherwise remote and reliant on long overland journeys to major urban centers. The airport handles domestic routes operated by Iranian carriers, linking Birjand to Tehran and other key Iranian cities. It plays a vital role in the regional economy and serves government, business, and leisure travelers alike. Despite its international designation, the airport primarily handles domestic traffic, with international operations being limited. Infrastructure improvements have been undertaken over the years to expand capacity and improve facilities for passengers.
