Iran is trying to re-engage with the global economy after years under crushing sanctions, and its airports will be important links to the outside world.
Tehran-Mehrabad was once the airport for all major flights into and out of Iran's capital. Since 2004, the airport has handled mostly domestic flights, while international travelers have been routed primarily through the newer Tehran Imam Khomeini airport.
Mehrabad is centrally located within the sprawling metropolis of Tehran, and the airport gives a little of the flavor of the country itself. CNBC recently reported from on the ground in Iran, and our team there captured images from the air hub. Click ahead for what Tehran-Mehrabad looks like from the inside.
