The government on Thursday said resumption of international flights will be considered on a case-by-case basis, depending on which countries they are coming from, after April 15 when the 21-day lockdown to fight the coronavirus ends in India. Civil Aviation Minister Hardeep Singh Puri also said Indians who are stranded in several foreign countries will have to wait till April 15 to return to India, suggesting that flights taking foreign nationals to their countries from India will not bring back any passengers. India has allowed countries like the US, UK and Germany to conduct special flights during the lockdown to take their citizens back home.
