Airport

Mashhad is served by the Mashhad International Airport, which handles domestic flights to Iranian cities and international flights, mostly to neighbouring Arab countries. The airport is the country's second busiest after Tehran Mehrabad Airport and above Tehran's Imam Khomeini International Airport.

It is connected to 57 destinations and has frequent flights to 30 cities within Iran and 27 destinations in the Central Asia, the Middle East, East Asia and Europe.

The airport has been under a US$45.7 Million vast expansion project which has been finished by opening a new Haj Terminal with 10,000 m area on 24 May 2010 and followed by opening a new international terminal with 30000 m area with a new parking building, a new custom storage and cargo terminal, new safety and fire fighting buildings and upgrades to taxiways and equipment. Another US$26.5 Million development project for construction of a new hangar for aircraft repair facilities and expansion of the west side of the domestic terminal is underway using a BOT contract with companies in the private sector.
