Last week, Pakistan said it refused a request by India to fly President Ram Nath Kovind through its airspace due to escalated tensions between the two countries over New Delhi’s decision to revoke special status to Kashmir.

President Kovind was forced to take a detour.

Civilians do not have to go through the same trouble as the President for now though Islamabad recently said it is considering closing the airspace again.

Pakistan reopened its airspace to India in mid-July after closing it in February when the Indian military launched an airstrike in its northern parts.

The airspace closure then forced planes into long detours that cost airlines millions of dollars because Pakistan lies in the middle of a vital aviation corridor.
