In a bold and calculated response to the recent Pahalgam terror attack in Jammu & Kashmir, India launched Operation Sindoor, a multi-pronged precision air strike campaign targeting at least nine terror camps located in Pakistan-occupied Kashmir (PoK) and within Pakistan. The operation, conducted under strict strategic protocols, has already begun reshaping India’s defence posture. However, the consequences are not limited to military affairs; the Indian aviation sector is already feeling the ripple effects economically, operationally, and geopolitically.

Heightened Security and Airspace Restrictions

In the immediate aftermath of Operation Sindoor, security at major airports across India was elevated to the highest level. Key hubs, including Delhi, Mumbai, and Srinagar, saw additional deployment of CISF and intelligence agencies. Airports near the northern and western borders, especially Amritsar, Jammu, Leh, and Srinagar, witnessed tightened security screening, impacting overall turnaround times.

Moreover, with Pakistan imposing restrictions on its airspace for Indian commercial carriers, flight diversions and extended air routes became inevitable. Several international airlines, including Air India and IndiGo, have already rerouted flights that previously traversed Pakistani airspace, particularly affecting Europe and Gulf-bound sectors.

Operational and Financial Impact on Airlines

According to aviation analysts, nearly 100 Indian commercial flights used to cross Pakistani airspace daily before the closure. The redirection of these routes over Hindu Kush and other mountainous regions is now adding up to 40–50 minutes of extra flight time, significantly increasing fuel costs and affecting on-time performance.

This re-routing poses unique operational safety challenges as well. While most commercial aircraft carry 12–15 minutes of emergency oxygen for cabin depressurisation, descents over the Hindu Kush region, due to higher altitudes, may require up to 25–30 minutes of oxygen. Older Air India Boeing 777s are equipped with extra oxygen tanks, but newer leased aircraft are not, necessitating a safety review.

As a temporary measure, DGCA has relaxed pilot duty time norms to accommodate longer flying hours and additional fuel reserves, but this adds scheduling complexity and potential cost burdens for carriers already navigating post-pandemic recovery.

Strategic and Diplomatic Moves

The Indian government is reportedly preparing to approach the International Civil Aviation Organisation (ICAO) to raise concerns over Pakistan’s airspace blockade. As per the 1944 Chicago Convention, airspace restrictions must not unreasonably interfere with international civil aviation unless absolutely necessary. New Delhi is expected to argue that airspace denial in peacetime violates global civil aviation norms and endangers safety.

This move would not only highlight India’s grievance at a global platform but may also serve as a litmus test for ICAO’s ability to enforce equitable airspace access, especially amid escalating geopolitical tensions.

Cargo Sector and Regional Connectivity

The air cargo sector, already under strain due to volatile fuel prices and global trade fluctuations, is another casualty of the current situation. India’s east-west cargo corridors, which rely heavily on time-sensitive operations, are likely to experience longer transit windows.

Furthermore, regional connectivity under UDAN and Defence MRO movements in border states could face logistical bottlenecks in the short term, especially as military priority airspace allocation increases in northern India.

Navigating Turbulent Skies

Operation Sindoor underscores India’s resolve in the face of cross-border terrorism, but it also amplifies the interconnectedness of national security and civil aviation. The Indian aviation sector, while resilient, is now under added operational and geopolitical pressure. Airlines, cargo operators, and regulatory agencies must coordinate seamlessly to maintain passenger safety, minimise financial losses, and uphold global aviation standards.

In the long term, this moment may catalyse greater investment in aviation security, airspace autonomy, and infrastructure upgrades, reinforcing India’s ambition to become a global aviation hub, prepared not just for growth but for adversity.
