IndiGo, one of India’s biggest passenger airlines, is facing major operational disruptions across the country, leading to the cancellation of more than 500 flights. The sudden interruptions have created long queues and crowding at several major airports, with passengers waiting for updates on their flight status.

This marks the fourth consecutive day of disruptions. Delhi airport has been affected the most, with all IndiGo flights cancelled until 3 pm. In Chennai, passengers continued to wait as the airport released an advisory listing the cancelled flights and requested travellers to check with their respective airlines for further updates.

The airline has attributed the crisis to several factors, including minor technical glitches, winter schedule adjustments, adverse weather, and updated crew rostering rules. However, IndiGo has not yet clarified how it plans to return to full operational strength.

The impact has been widespread across other cities as well. Bengaluru airport saw at least 102 cancellations on Friday morning, including 52 arrivals and multiple departures. Hyderabad airport also reported 92 cancellations, adding to the nationwide disruption.

A quick resolution may not be expected immediately, as IndiGo has informed the DGCA that complete restoration of services will take place only by February 10. Issuing a second apology in two days, the airline said, “We extend a heartfelt apology to all our customers and industry stakeholders who have been impacted by these events.”

Passengers scheduled to travel today are strongly advised to check their flight status before heading to the airport.
