It is the fourth day of cancellations after the low-cost company failed to plan for new regulations that require longer rest for employees and limit night flying hours for greater safety.

What IndiGo flights have been cancelled?
 

Delhi airport announced that all IndiGo departures, believed to total 235, had been cancelled on Friday.

Chennai airport also said all of its IndiGo flights to other large cities were cancelled up to 6 p.m. on Friday.

Other major hubs also announced widespread cancellations, with 104 flights grounded in Mumbai, 102 in Bengalaru, and 92 in Hyderabad.

A temporary exemption from stricter night-duty limits was granted on Friday, offering some short-term breathing room. The Civil Aviation Ministry says the airline underestimated how the new rules would affect pilot availability.

Other carriers have not reported similar problems, and shares in the low-cost carrier dropped nearly 3% on Friday as part of a weekly slump of 10.3%.

Meanwhile, opposition lawmakers have demanded a discussion in parliament as travelers continue to face significant delays.

What is the impact of the IndiGo cancellations?
 

The low-cost carrier operates roughly two-thirds of India's domestic flights and has warned that normal operations will not be restored until February 10. IndiGo has said the shortages stem from planning gaps as it attempted to implement the second phase of the new duty rules.

Passengers have been stranded at major airports, waiting for hours with little information. Some have slept on terminal floors. The scenes have been tense, with reports of arguments and chants of frustration at Bengaluru airport.
