TEHRAN (ISNA)- Head of Iranian Aviation Organization Alireza Jahangiri said establishing Iran-US flight line is under investigation.
"The issue is under pursuit and investigation and will be announced whenever it is accomplished," he said.
Jahangiri also added that no exact time frame can be determined for establishing the flight line.
On September 30, Akbar Torkan, former acting head of the High Council of Iranian Affairs Abroad, said that Iranian President Hassan Rouhani has issued an order to study the option of resuming direct flights between the two countries in order to reduce the problems of Iranian nationals residing in the US.
More than one million Iranian nationals live in the United States. Direct flights between Iran and America were halted after Iran's Islamic Revolution of 1979.
