Bold issue: IndiGo’s operations are faltering as tech glitches and congestion ripple through India’s busiest airports.
IndiGo, India’s largest airline, reported over several days that multiple flights were delayed or canceled because of telecommunications and IT issues, along with airport congestion and operational needs. This comes after a rough run of disruptions at major hubs like Delhi, Mumbai, and Bengaluru, and follows a broader outage in India’s air-traffic-control system that had grounded hundreds of flights at Delhi last month.
On Tuesday, IndiGo’s on-time performance dropped to a dismal 35%, the lowest among Indian carriers, though the airline typically posts well over 80% punctuality at key airports such as Delhi and Mumbai. The latest disruptions contributed to a patchwork of delays across the country’s three busiest airports, with Delhi accounting for the majority of delayed flights as of 0909 GMT on Wednesday, according to Flightradar24 data. Roughly 600 flights were delayed nationwide at that time.
An IndiGo spokesperson said the team is working diligently to restore normal operations as soon as possible, but did not disclose specific causes for the delays and cancellations. Earlier this month, IndiGo and other global carriers faced a software glitch affecting roughly 200 Airbus A320s, which underscored how fragile the aviation tech stack can be during busy travel periods.
Market reaction followed closely: IndiGo’s stock dipped about 2% after the update, though the stock has risen roughly 23% year to date. IndiGo commands a domestic market share above 60% and operates more than 2,200 flights per day, with ongoing international expansion that positions it as a challenger to Air India’s traditional dominance. That said, recent quarters have been pressured by a strong U.S. dollar and softer demand following safety incidents and geopolitical tensions.
Air India reported a 67.2% on-time rate on Tuesday and cited a third-party system disruption affecting check-in at several airports. Delhi Airport also noted that some domestic carriers were facing "operational challenges" that could cause delays or schedule changes.
