IndiGo Airlines is currently facing a severe operational crisis, resulting in the cancellation of over 470 flights and significant delays affecting thousands of passengers. The Directorate General of Civil Aviation (DGCA) has issued a show-cause notice to IndiGo's CEO, Pieter Elbers, demanding an explanation for the airline's failures to comply with new flight duty time limitations. Union Civil Aviation Minister Ram Mohan Naidu has emphasized the need for immediate passenger relief and has launched a high-level inquiry into the situation.
