IndiGo shares extend slide for 6th session, plunge 7% amid flight chaos

Shares of InterGlobe Aviation , the parent company of low-cost carrier IndiGo, extended their decline for the sixth straight session on Monday, slipping nearly 7% in early trade. The stock has tumbled more than 15% since November 27, weighed down by a severe operational meltdown —the worst crisis in IndiGo’s 20-year history — marked by large-scale flight cancellations and delays across its network.

IndiGo shares slipped as much as 6.6% to an intraday low of ₹5,015 on the BSE, after closing 1.2% lower at ₹5,371.30 in the previous session. At the time of reporting, the stock was trading at ₹5,173.05, down 3.7%, with a market capitalisation of around ₹2 lakh crore.

The counter saw strong volume, with over 1 lakh shares changing hands compared with the two-week average of 68,000 shares.

The airline stock hit a 52-week high of ₹6,225.05 on August 18, 2025, and a 52-week low of ₹3,946.40 on January 22, 2025. Despite the recent selloff, IndiGo has gained 15% over the past year. However, it has dropped more than 9% in the last six months and 7.5% over the past month.

From a technical perspective, the stock remains above its 200-day moving average but is trading below its 5-day, 20-day, 50-day and 100-day moving averages, signalling short-term weakness.

Over the past week, IndiGo has faced a severe operational breakdown that led to the cancellation of more than 2,000 flights, leaving thousands of passengers stranded across the country. After days of widespread disruptions, the airline on Sunday said its operations had shown “significant and sustained improvement,” though the fallout continues.

The crisis began on November 29, triggered by an urgent mandatory software patch for Airbus A320 aircraft, issued under a global technical advisory. IndiGo had nearly 200 planes requiring the update, and the compressed maintenance window threw crew rosters into disarray. The situation was worsened by the full enforcement of stricter Flight Duty Time Limitations (FDTL) norms from November 1, which require longer rest periods and reduce allowable flying hours for pilots.

The airline said it expected to operate over 1,650 flights on Sunday, up from about 1,500 the previous day. On-time performance also improved sharply to 75%, compared with roughly 30% a day earlier.

IndiGo added that its refund and baggage-handling systems are now fully functional for both direct and agency bookings. It also urged passengers to check their flight status before travelling to the airport, sharing links to its status and refund portals.

The carrier said it is increasingly confident of restoring stability across its network and now expects operations to return to normal by December 10 — slightly earlier than its earlier estimate of December 10–15.

In response to the crisis, IndiGo has set up a dedicated crisis management group, with the board stepping in on the first day of widespread delays to assess the situation and streamline decision-making. Despite this, the airline continues to face a steady flow of passenger complaints.

Meanwhile, IndiGo has to submit a detailed reply to the show-cause notice issued by the Directorate General of Civil Aviation (DGCA) by 6 pm today.
