Nasser Aqaei, the director of the Iran Airports and Air Navigation Company, said the discounts would go to the top eight airlines providing transit income as well as airlines boosting their flights by 20 percent, Reuters reported.

However, no general cut in fees are planned, he said.

Iran is one of many countries to charge so-called overflight fees, which are generally used to fund services such as air traffic control, weather data, and aeronautical information.

The planned discounts still have to be approved by the government, Aqaei said.

Iranian civil aviation authorities have said that flight routes to major destinations in the Middle East and in Asia would resume in the near future by other Iranian airlines.

Iran Air suspended all European flights in mid-March after tight restrictions were imposed on arrivals in major Western European countries because of the growing number of cases testing positive for the COVID-19, the disease caused by the new coronavirus.
