The widespread disruptions in IndiGo flights, resulting from the airline’s failure to plan for aviation regulations communicated to industry more than a year in advance, could result in financial damage from loss of revenue as well as potential penalties for cancellations, Moody’s Ratings said on Monday. In a note, Moody’s said the disruptions are “credit negative” for the airline. “Despite temporary reprieve, failure to effectively plan for new aviation regulations is credit negative,” it added.
 
The disruptions, which coincided with peak winter schedules, resulted in over 1,600 flight cancellations on December 5, after similar operational issues in November left more than 1,200 flights grounded. Flights cancellations started on December 2 and the airline is yet to restore normalcy. More than 500 flights were cancelled on Monday.
