The government has asked airlines to carry out risk assessment on international flight operations amid escalating tensions in the Middle East, said Mr Vumlunmang Vualnam, Civil Aviation Secretary. Air India, Vistara, IndiGo and various international airlines have opted for alternative flight paths to the West and are avoiding Iranian airspace against the backdrop of tensions flaring up between Iran and Israel. The Directorate General of Civil Aviation (DGCA) is handholding and interacting with the airlines and is in touch with the External Affairs Ministry. Besides, Air India has temporarily suspended flights to Tel Aviv. The alternative flight paths have increased the duration of some of the international flights by around half an hour, said a report.
