List of airlines of Iran

Iran has several private and public airline companies in operation. The oldest is the Iranian Airways Company, founded in 1944 (known as Iran Air since 1961).
As of June 2009, Iranian planes fly 45 international flight routes. Most of the fleet of Iranian airlines today consist of old Boeings and used or leased Airbus and regional jets like British Aerospace 146 and Fokker 100. Sanctions from the United States prevents Iran from purchasing most new western made aircraft to update its rapidly aging fleet. Iran's own poor safety regulations and mismanagement on behalf of the Iran civil aviation authorities has also been a known factor to blame. This has resulted in a series of ongoing disasters and incidents. Because of this, in the last 25 years there have been 17 plane crashes, and 1500 deaths (From 2000 to 2006, 11 Iranian plane crashes claimed about 700 lives). 
Iran has initiated manufacturing aircraft on its own such as the IR.AN-140. A number of 108 airliners have been added to the fleet of Iranian passenger planes during the last five years. As at July 2015, Iran had 251 commercial planes with 41,218 seats and 6 cargo planes, many (around 100) of which are not functional because of a lack of spare parts.
In 2016, at the risk of seriously undermining or destroying its own naissant domestic aviation industry, Iran announced its intention to buy over 200 heavy airplanes from Boeing and Airbus at a cost of more than $50 billion - which exceeds the entire fleet of Air France who operates in a country that has seven times the number of air travelers as Iran. This, in addition to more planned orders of 100 medium-range planes to Japan's Mitsubishi, Brazil's Embraer and Canada's Bombardier. Iran says these deals include authorization to maintain these planes inside of Iran, including the production of parts and training.
As of 2014, Iranian airliners spend 25% of their earnings on aircraft maintenance on average while the global average is only 6%. Iran plans to liberalize airfare prices by 2015. As of 2015, foreign airlines earned $3bn in Iran annually. Iranian airlines handle a total of 50 million passengers each year (2016).
Iran plans to buy 400 passenger planes by 2025 worth some $20 billion, if US sanctions are lifted.
