InterGlobe Aviation Ltd., which operates IndiGo, saw its share price drop sharply on Monday, December 8, 2025. The stock fell nearly 7% in early trade and looked set to extend losses to a seventh straight session. Investors reacted to signals of ongoing operational stress at India’s largest airline by market share.
Delhi Airport added to concerns on Sunday when it warned that IndiGo flights may continue to experience delays. The airport advised passengers to confirm flight status before travel. The caution followed widespread cancellations and delays last week that stranded many passengers and drew government attention to rising airfares.
The Directorate General of Civil Aviation (DGCA) issued a show cause notice to IndiGo CEO Pieter Elbers to review the airline’s readiness for updated Flight Duty Time Limitations (FDTL) rules. The regulator asked for a response by 6 pm on Monday, according to market updates. IndiGo had received advance information on the revised duty regulations.
The DGCA said IndiGo showed shortcomings in planning, supervision, and resource management. The regulator linked the disruption to gaps in staffing, rostering, and scheduling that should meet the new FDTL framework. It also indicated potential non-compliance with Aircraft Rules, 1937, and related norms on duty hours, flight time limits and rest periods.
InterGlobe Aviation reported a net loss of ₹2,582 crore for the September 2025 quarter, compared with a loss of ₹987 crore a year earlier. The airline cited higher foreign exchange expenses. Revenue from operations still increased 9.3% year on year to ₹18,555 crore, supported by capacity and network management.
Capacity rose 7.8% to 41.2 billion available seat kilometres, while passenger numbers increased 3.6% to 28.8 million. EBITDAR fell to ₹1,114 crore from ₹2,434 crore, and the margin narrowed to 6% from 14.3%. Investors will track whether the current disruptions affect guidance for the next two quarters.
The stock hit an intraday low near ₹5,001 and traded around ₹5,100 in late morning deals. Market data showed the share price has fallen about 13.5% so far in December 2025. The company’s market capitalisation also declined from roughly ₹2.28 trillion to ₹1.94 trillion during the sell-off, eroding more than ₹34,000 crore in investor value.
Some analysts highlighted a multi-year support zone around ₹5,050 and placed interim support in the ₹4,800 to ₹4,600 range. They also flagged risks from higher refunds and staffing costs under the new FDTL structure if disruptions persist.
SpiceJet share price advanced as much as 12% on Monday and extended a two-day rally. Traders linked the move to higher bookings as some travellers shifted to alternatives during IndiGo’s delays. Trading volumes also rose in SpiceJet.
