Pakistan reopened its airspace on 15 July to all civil traffic, ending around six months of restrictions that impacted aircraft flying over the country.
The Pakistan Civil Aviation Authority issued a NOTAM reopening the airspace shortly after 19:00 GMT allowing civil traffic to use all published air traffic routes.
The country closed its airspace on 26 February after a flare-up in tensions with India over airstrikes in the disputed Kashmir region.
While it has reopened some sections of its airspace, the area along Pakistan's eastern border with India had been closed indefinitely.
That has resulted in airlines operating flights between Asia and Europe having to operate longer routes to avoid the area. Indian carriers have also been particularly affected, with most northbound services usually transiting through the affected airspace.
