The targets of the ads at airports are merchants, businessmen, and regular passengers. Given the fact that a large portion of passengers spend significant time at airports, the effect and scope of airport advertisements are considerably distinct from typical commercial material. Sima-ara Corporation is proud to be in charge of delivering the message of various ads to over 26 million passengers annually at the airports of Tehran and Mashhad.
