Shares in IndiGo fell an additional 8% on Monday, extending total losses to 16% as the airline grapples with an operational crisis and potential regulatory action. The turmoil has erased about $4 billion from its market cap, now valued at approximately $21 billion.

The airline's inability to prepare for new regulations on night flying has led to mass flight cancellations, stranding passengers and prompting government intervention to control rising airfares.

Immediate market implications may include increased scrutiny on operational practices and potential shifts in passenger preferences.
