Austrian Airlines is set to relaunch services to Tehran effective from 11 March 2014.  The commencement of flights depends on final regulatory approval. The flights will be operated five times a week for the duration of the company’s summer schedule, using an Airbus A320 or A319 bearing the flight number OS 871/2. The service will be bookable from 15 January 2014 onwards. Austrian Airlines removed flights to Tehran from its schedule in January 2013 for commercial reasons. These included the strong inflation of the Iranian currency, the rial, and the effects of the economic and political sanctions on the ground in Iran. Source: Travel Daily
