Pakistan opened its airspace to civil aviation on Tuesday, following months of restrictions imposed in the wake of a standoff with neighbouring India. “With immediate effect Pakistan airspace is open for all type of civil traffic on published ATS (Air Traffic Service) routes,” according to a Notice to Airmen (NOTAM) published on the Civil Aviation Authority’s website. The move by Pakistan, which lies in the middle of a vital aviation corridor, offers a welcome break for international airlines after the airspace restrictions affected hundreds of commercial and cargo flights each day, adding to flight time for passengers and fuel costs for airlines. India’s Ministry of Civil Aviation said that after the lifting of the NOTAMS, there were no further restrictions on airspace in either country. “Flights have started using the closed air routes, bringing a significant relief for airlines,” it said. Pakistan closed its airspace for all civilian traffic after India carried out air raids on Pakistani territory on February 26, following a suicide attack in Indian-held Kashmir (IHK) town of Pulwama earlier that month. India blamed Pakistan for the February 14 suicide bombing, a charge the latter denied. Pakistan carried out its own retaliatory strikes on targets in IHK on February 27, with an ensuing dogfight seeing at least one Indian fighter jet shot down. Tensions defused slightly when Pakistan returned the Indian air force pilot who was shot down two days later, but both countries’ military forces remained on high alert. Partial operations at Pakistani airports resumed once the immediate crisis passed but restrictions continued to affect many international carriers using Pakistani airspace. Pakistan’s announcement came hours after United Airlines Holdings Inc said it was extending the suspension of its flights from the United States to Delhi and Mumbai in India until October 26, citing continued restrictions of Pakistani airspace.
