IndiGo Flight 6E 6115 Diverts to Hyderabad Following In-Flight Smoke Incident
An IndiGo flight from Delhi to Chennai was forced to make an emergency diversion to Hyderabad on 11 October 2026 after smoke emerged from a passenger's personal electronic device.
The Core Development
Flight 6E 6115 was operating its scheduled route from Delhi to Chennai when cabin crew detected smoke emanating from a personal electronic device. Pilots immediately executed safety protocols, diverting the aircraft to Rajiv Gandhi International Airport in Hyderabad.
The aircraft landed safely. IndiGo cabin crew contained the situation onboard, and the airline subsequently deployed an alternative aircraft to transport passengers to their final destination in Chennai. While preliminary reports suggest a power bank may have caught fire, IndiGo has not officially confirmed the specific device or the exact cause of the ignition.

Why This Matters
From a logistical perspective, this incident demonstrates how a single consumer electronic accessory can paralyze operations between two of India's busiest aviation hubs. The diversion requires significant ground handling resources, unplanned aircraft rotations, and passenger re-accommodation.
Our analysis of the flight data and current regulations indicates a growing tension between consumer reliance on high-capacity lithium-ion batteries and aircraft safety. Lithium-ion batteries are prone to "thermal runaway"—a rapid increase in heat that can lead to cell failure and fire. When these devices are stored in overhead bins or checked luggage, they become "hidden" hazards. This is why IndiGo and other carriers now mandate that power banks remain within personal reach; immediate detection is the only way to prevent a localized smoke event from becoming a catastrophic cabin fire.
Industry Outlook
The aviation industry is moving toward stricter enforcement of the ICAO technical requirements introduced on 27 March 2026. Passengers should expect tighter scrutiny of battery carriage.
Current Regulatory Framework:
- Quantity: Maximum of two power banks per passenger.
- Usage: Charging power banks onboard is prohibited.
- Interconnectivity: Using a power bank to charge other devices during flight is prohibited/not recommended.
- Placement: Hand baggage only; storage in overhead bins or checked luggage is strictly forbidden.
Future safety audits will likely focus on passenger compliance with these rules, as the risk of battery-induced diversions continues to rise with the proliferation of high-density portable chargers.
