"With immediate effect, Pakistan airspace is open for all type of civil traffic on published ATS (Air Traffic Service) routes," according to a so-called Notice to Airmen (NOTAMS) published on July 16 on the authority's website.

Pakistan closed its airspace in February after a standoff with India in the wake of an attack by a Pakistan-based militant group on a police convoy in Indian-controlled Kashmir that killed 40 paramilitary police.

Both countries carried out aerial attacks over the other's territory during the standoff and warplanes fought a brief dogfight over the skies of the disputed Kashmir region.

Partial operations at Pakistani airports resumed once tensions eased, but restrictions continued to affect many international carriers using Pakistani airspace.
