An IndiGo flight travelling from Delhi to Chennai was diverted to Hyderabad on Sunday, October 11, after smoke was detected from a passenger’s personal electronic device onboard, prompting a safety response by the cabin crew.
The flight, numbered 6E 6115, landed safely at Rajiv Gandhi International Airport in Shamshabad, Hyderabad. According to the airline, the pilots diverted the aircraft in accordance with established safety protocols after smoke was detected from the device.

Key Highlights
Important points readers should notice.
Issue/Event: IndiGo flight 6E 6115 was diverted from its Delhi–Chennai route after smoke was detected from a passenger’s personal electronic device.
Location: Rajiv Gandhi International Airport, Shamshabad, Hyderabad, Telangana.
Authority/Organisation: IndiGo, the flight crew and airport authorities.
Action Taken: The pilots diverted the aircraft under established safety protocols. The crew brought the situation under control, and an alternative aircraft was arranged for passengers travelling onward to Chennai.
Impact: The flight landed safely, but the incident caused travel disruption and renewed attention to the safe carriage and storage of power banks onboard aircraft.
IndiGo said the cabin crew responded promptly and brought the situation under control. The airline also arranged an alternative aircraft to carry passengers onward to Chennai and expressed regret for the inconvenience caused by the unexpected disruption.
Reports identified the device as a passenger’s power bank, reportedly located in an overhead luggage compartment. However, the airline’s quoted statement did not explicitly confirm that the device was a power bank or specify the precise cause of the smoke. Those details should therefore be distinguished from the airline’s confirmed account of the diversion.
The incident has renewed attention on the risks associated with lithium-ion batteries carried by passengers. Although power banks are commonly used to charge phones and other electronic devices, damaged or malfunctioning batteries can overheat and, in some circumstances, ignite.
Editorial Analysis
Why This Matters
The incident highlights a safety risk associated with a widely used consumer device. Power banks are carried by passengers on domestic and international journeys, but their rechargeable batteries can pose a hazard if they malfunction. For travellers, the key lesson is that carrying a power bank is subject to specific rules. Keeping it within reach, avoiding its use during flight and reporting signs of overheating can help the crew respond promptly. For airlines, battery incidents require clear passenger communication, effective crew training and adherence to established emergency procedures. A safe landing and the arrangement of a replacement aircraft demonstrate the importance of having procedures to manage unexpected events. The investigation and any subsequent technical findings will be needed to establish the exact cause of this incident. Until then, the confirmed facts are the detection of smoke, the diversion and the safe landing in Hyderabad.
Why was the flight diverted?
When smoke or a possible fire is detected inside an aircraft, flight crews must treat the situation as a potential safety threat. A battery-related incident can develop quickly, and smoke may affect passengers and crew even when the source appears small.
In this case, IndiGo said the pilots diverted the aircraft after smoke was detected from a personal electronic device. The plane landed safely in Hyderabad, where the passengers’ onward journey was arranged on another aircraft.
A diversion is a precautionary aviation decision. It allows the aircraft to land at a suitable airport so that the situation can be assessed and any necessary safety or technical checks can be carried out.
The incident does not, by itself, establish that the aircraft was at risk of a crash. It does show why smoke or a suspected battery fire onboard requires an immediate response.
Power bank safety rules passengers should know
IndiGo’s published baggage policy states that power banks and spare or loose lithium batteries must be carried in hand baggage. They must remain within the passenger’s personal reach and must not be placed in overhead compartments or checked baggage.
The airline also states that power banks must not be used to charge devices or recharged during a flight. Its policy includes restrictions on battery capacity and requires appropriate precautions to prevent short circuits.
These rules are important because a battery stored inside an overhead bin may be harder to monitor and access quickly if it begins overheating. Keeping a power bank within reach can help a passenger notice unusual heat, smoke or odour and alert the cabin crew promptly.
Passengers should follow the specific airline’s current rules before travelling. They should not attempt to handle a smoking or burning battery themselves unless directed by trained crew members.
How lithium-ion batteries can catch fire
Power banks generally use rechargeable lithium-ion or lithium-polymer battery technology. Under normal conditions, these batteries are designed to store and release energy safely. Problems can arise if a battery is damaged, defective, improperly manufactured or exposed to conditions that cause an internal short circuit.
A process known as thermal runaway can cause a battery’s temperature to rise rapidly. The resulting heat may lead to smoke, fire and the release of hazardous gases. Once a battery enters this state, extinguishing visible flames does not necessarily mean the device is no longer hazardous.
This is one reason aviation safety procedures place particular emphasis on identifying battery incidents early and ensuring that trained crew members manage the response.
The precise cause of the smoke aboard flight 6E 6115 has not been established in the airline statement reviewed for this report. It would be premature to attribute the incident to a particular power bank brand, battery defect or passenger action without verified findings.
What happened to the passengers?
The aircraft landed safely at Hyderabad airport. IndiGo said an alternative aircraft was arranged to continue the journey to Chennai, while the airline also apologised for the disruption and said it was making efforts to minimise inconvenience.
The diversion meant that passengers could not continue their original journey as planned on the same aircraft. Further information about the duration of the delay and any subsequent technical findings should be added only when reliably confirmed.
The incident also serves as a reminder that safety-related diversions can occur even when the crew successfully contains a problem. Such decisions prioritise the safety of passengers and crew over maintaining the original flight schedule.
