Mehrabad International Airport (THR)

Mehrabad International Airport is Tehran's historic aviation hub and Iran's busiest airport by passenger volume, handling over 12.3 million passengers annually despite primarily serving domestic operations since 2007. Originally opened in 1938 with international recognition by the International Civil Aviation Organization in 1949, the airport served as Iran's primary international gateway until the opening of Imam Khomeini International Airport. Located at an elevation of 3,962 feet above sea level in central Tehran, Mehrabad remains strategically important as the primary hub for Iran's major airlines and the headquarters of Iran Air and the Iran Civil Aviation Organization. The airport features three parallel runways designed to handle high-volume domestic traffic: Runway 09/27 measuring 1,556 feet, and two longer parallel runways 11L/29R (13,098 feet) and 11R/29L (13,248 feet), providing excellent capacity for simultaneous operations. This infrastructure enables the airport to efficiently manage its status as a hub for most Iranian airlines, serving domestic routes to 41 cities across Iran. The runway configuration and length accommodate everything from regional turboprops to wide-body aircraft used on longer domestic routes within Iran's vast territory. The terminal complex consists of multiple specialized facilities: Terminal 1 exclusively serves Kish Air, Zagros, and Varesh Airlines; Terminal 2 functions as the primary hub for Iran Air, Iran Air Tours, Meraj Airlines, Qeshm Air, and Ata Airlines, featuring dedicated jet bridges for Meraj Airlines and handling all cargo operations; while Terminals 4 and 6, opened in 2007, manage departures and arrivals respectively for all other carriers. This terminal segregation system helps optimize passenger flow and reduces congestion across the airport complex. Mehrabad Airport offers comprehensive ground transportation connectivity, including two dedicated Tehran Metro stations serving the airport complex: one for Terminals 1 and 2, and another for Terminals 4 and 6, providing efficient urban transit links to central Tehran. The airport maintains its international airport designation and infrastructure despite focusing primarily on domestic operations, with facilities including shops, cafes, airline service desks near check-in halls, and comprehensive passenger amenities across all terminals, making it a vital transportation hub for Iran's domestic aviation network.
