Mumbai Airspace Congestion Rises as Airlines Reroute

Air Traffic Disruptions: Mumbai Becomes Key Hub Amid Pakistan Airspace Closure

MUMBAI – Following Pakistan’s airspace closure on April 24, 2025, major airlines such as Air India (AI) and IndiGo (6E) have had to adjust their flight routes, significantly increasing air traffic over Mumbai (BOM). This disruption is reshaping the aviation landscape, as airlines navigate new paths to maintain their schedules.

Mumbai’s Air Traffic Control (ATC) is now managing an influx of rerouted flights while handling its usual daily operations. The closure of Pakistani airspace has led to a surge in traffic from northern India and Southeast Asia, forcing airlines to find alternative routes and making Mumbai a critical hub for international travel.

Air Traffic Rerouting Over Mumbai

Mumbai’s ATC is currently overseeing approximately 950 to 970 daily flights, combined with around 2,000 overflights and rerouted flights from northern India and Southeast Asia.

• Previously, about 130 flights from northern India to destinations in Europe and the Americas used the Bhopal-Ahmedabad-Karachi-Muscat route, now rerouted through Ahmedabad to reach Muscat via Mumbai.
• Additionally, around 250 flights from Southeast Asia to various regions have shifted their paths to traverse Mumbai airspace, avoiding the now-closed routes to Pakistan following the recent military operations.

Due to these challenges, foreign carriers such as Emirates (EK) and Qatar Airways (QR) are also revising their flight plans, resulting in a significant 20% increase in the workload for Mumbai ATC.

Impact of Airspace Closures

The ongoing closure of Pakistan’s airspace, extended until May 25, 2025, has profound effects, impacting 70 to 100 daily Indian flights. Carriers like Air India are now rerouting flights over the Arabian Sea, which adds approximately 2 to 2.5 hours to journeys from Mumbai (BOM) to major destinations like London (LHR) and New York (JFK).

Moreover, India has reciprocated by closing its airspace to Pakistani carriers, including Pakistan International Airlines (PK), effective April 30, 2025, further complicating the operational landscape for both nations.

Impact on Airline Operations

Airlines based in Mumbai are adapting to the increased traffic by filing new flight plans.

• Air India has adjusted its routes for flights from Delhi (DEL) to London (LHR) and from Mumbai (BOM) to New York (JFK), adding between 600 and 800 nautical miles to their journeys.
• IndiGo is looking into a hub-and-spoke model through Mumbai to consolidate passengers from northern India, similar to its existing strategy for flights from Kolkata (CCU) to Vietnam.

Additionally, foreign carriers such as Singapore Airlines (SQ) and Lufthansa (LH) have also opted to avoid Pakistani airspace, which has led to a 15% increase in overflights through Mumbai, according to data from FlightRadar24.

Global Aviation Implications

The rerouting of flights through Mumbai has broader implications for global aviation. Carriers with overflight rights, like Emirates, could gain a competitive advantage, while Indian airlines may incur higher operational costs, potentially leading to increased airfares.

The International Air Transport Association (IATA) estimates that prolonged airspace closures could result in a staggering $1.8 billion annual impact on Indian carriers. Despite the increased traffic, Mumbai’s role as a transit hub has manifested in a 10% rise in international connections, according to OAG Aviation data, although it raises concerns about congestion without necessary infrastructure enhancements.

Moreover, the ongoing tensions have prompted travel warnings from eight countries, including the U.S., U.K., and Canada, regarding travel to Jammu and Kashmir and regions near the Pakistan border, emphasizing the risks associated with the current geopolitical climate.

In conclusion, as Mumbai continues to adapt to these significant air traffic changes, the evolving situation underscores the need for robust infrastructure and strategic planning to accommodate the increasing demands of global air travel.
