Pakistan's aviation authorities have issued a new notice to airmen (NOTAM) extending the ban on Indian aircraft and airlines from using its airspace until 05:29 AM India time on May 24, 2025. This closure, which began on April 24, 2025, following the Pahalgam terror attack, has resulted in a reciprocal airspace ban, with India expected to extend its own restrictions on Pakistani airlines. The ongoing ban affects approximately 800 weekly flights operated by Indian airlines, primarily impacting routes to destinations in West Asia, Europe, and North America. As a result, Indian carriers are forced to take longer and more expensive routes, leading to increased operational costs. Air India estimated that the closure could cost it around ₹4,000 crore (roughly $480 million USD) annually. The situation has been exacerbated by the ongoing war in West Asia, which has already strained flight operations due to increased fuel prices and airspace restrictions. In contrast, the impact of India's airspace closure on Pakistan has been minimal, as Pakistan International Airlines (PIA) has limited international operations compared to Indian airlines.
