Tensions between India and Pakistan have sharply escalated following the recent Pahalgam terror attack, prompting India to take a decisive aviation-related step. On Wednesday, India issued a Notice to Air Missions (NOTAM) formally closing its airspace to all Pakistan-registered, operated, owned, or leased aircraft, including both civilian and military planes.
The NOTAM is effective from April 30 to May 23, 2025, during which no Pakistani aircraft will be permitted to enter Indian airspace.
India's decision to shut its airspace for Pakistani aircraft is a retaliatory response to Islamabad's earlier move to ban Indian carriers from using its airspace, effectively mirroring the restriction.
India's latest strategic move is expected to force Pakistani airlines to reroute their flights over countries like China or Sri Lanka to reach Southeast Asian destinations.
According to reports, the Indian government is also considering imposing a ban on Pakistani ships from docking at Indian ports, further escalating economic and logistical pressure on Islamabad.
Pakistan's move to bar Indian airlines from using its airspace severely impacts international flight routes operated from north Indian cities to the West.
The airspace ban is projected to cost Indian airlines an additional Rs 77 crore per week, translating to over Rs 306 crore per month, according to rough estimates based on the current volume of international flights and extended flight times.
The airspace closure is forcing airlines to reroute, resulting in additional flight durations and subsequent cost escalations:
Aviation industry officials also point out that longer flight paths pose challenges related to crew duty limits, payload restrictions, and aircraft turnaround times.
Data from aviation analytics firm Cirium shows that over 6,000 one-way international flights were scheduled by Indian carriers in April. Of these, about 3,100 two-way flights were operated from north Indian cities using both narrow-body and wide-body aircraft.
Budget airline IndiGo has already cancelled flights to Almaty and Tashkent due to range limitations under the revised routes.
Air India, Air India Express, SpiceJet, and Akasa Air have not officially announced flight cancellations yet. While Air India and IndiGo operate long-haul wide-body aircraft such as the Boeing 777 and 787, others like SpiceJet and Akasa Air, which primarily use narrow-body aircraft, could soon face operational constraints.
