IndiGo flight disruptions: Board approves appointment of Captain John Illson for independent expert review

IndiGo’s Board on Friday (December 12, 2025) had approved the appointment of Chief Aviation Advisors LLC, led by Captain John Illson, to conduct an independent expert review and root cause analysis of the massive flight disruptions for the airline.

A press statement said he brings more than four decades of aviation experience across the FAA, ICAO, IATA and major global carriers.

Captain Illson brings in extensive expertise in global aviation strategy, customised consulting, safety leadership, setting international standards and new aircraft technologies.

The statement added that the objective is to conduct an independent root cause analysis of the recent operational disruption, besides opportunities for improvement.

This decision follows the recommendation of the Crisis Management Group (CMG) constituted by the IndiGo Board. As part of its assessment, the CMG advised commissioning an independent expert review in the matter.

With the Board’s approval now in place, the review will begin at the earliest and the expert reviewer will submit a comprehensive report to the Board upon completion.
