The restriction, first imposed on April 30 following the Pahalgam terror attack that killed 26 civilians, was initially meant to last a month, but has since been extended multiple times.
Pakistan, in a reciprocal move, has also prolonged its airspace ban for Indian aircraft until the same date. Indian carriers will not be permitted to overfly Pakistan.
The bans are part of wider measures taken by both countries in the aftermath of the April 22 terror attack. NOTAMs (Notice To Airmen) are notices used in global aviation to alert pilots and airlines about critical changes or restrictions that may affect flight operations.

The prolonged airspace closure has increased flying times and fuel costs for Indian carriers flying internationally.
Airlines are forced to take longer alternate routes, adding anywhere between 30 minutes to over two hours on certain international sectors, particularly for long-haul flights from Delhi to Europe, the Middle East and North America.
