Indian airlines faced a sharp drop in international passengers during the April–June 2026 quarter, with Air India and IndiGo reporting declines of 35% and 15.4%, respectively. The dual impact of the US-Iran conflict and extended Pakistan airspace closures is forcing airlines to take longer, more expensive routes. This operational stress is hurting profit margins and driving up fuel costs while some foreign carriers gain market share.
Indian aviation companies faced a challenging April–June 2026 quarter as geopolitical tensions and airspace restrictions hit their international operations. Data from the Directorate General of Civil Aviation (DGCA) shows that total international passenger traffic from India dropped by 10.5% during the period. Homegrown airlines bore the brunt of this decline, reporting a collective 26% reduction in international passenger carriage.
Air India Group saw its international traffic fall by 35%, while IndiGo, the country’s largest private airline, reported a 15.4% decline in international passengers. These figures reflect the significant hurdles airlines are facing in maintaining their normal flight schedules.
At the heart of the issue is the continued closure of Pakistani airspace for Indian-registered flights, which has been in place since April 2025 and is currently expected to last until September 24, 2026. This restriction forces many international flights, especially those traveling between northern India and the West, to take longer, indirect routes. Furthermore, the ongoing US-Iran conflict has created additional instability, requiring further rerouting of flights away from affected areas.
For investors, the primary concern lies in the financial impact of these disruptions. Fuel costs typically account for 35% to 40% of an airline's total operating expenses. The need to take longer flight paths significantly increases fuel consumption, directly pressuring profit margins. The extent of these operational struggles was evident by the approximately 26,000 international flights cancelled by Indian carriers by July 20, 2026. These cancellations represent not only a loss of revenue but also the difficulty of managing capacity in a volatile environment.
In contrast, many foreign airlines have been able to navigate these challenges more effectively. Carriers like Emirates have maintained or even increased their traffic from India, as they are not subject to the same airspace restrictions. This allows them to operate more direct and cost-efficient routes, which can be more appealing to passengers and more sustainable for the airline’s bottom line.
Moving forward, the financial recovery of Indian airlines will depend on several factors. Investors should watch for any updates regarding the opening of Pakistani airspace, as this is the most direct way for these carriers to reduce their fuel burn and improve operational efficiency. Additionally, any major movement in global jet fuel prices will be a key monitorable, as it directly impacts the ability of these companies to protect their profit margins amid these external pressures.
