Why was IndiGo flight 6E 6115 diverted to Hyderabad? What happened to passengers

IndiGo flight 6E 6115 was diverted from its Delhi–Chennai route to Hyderabad on October 11, 2026, after smoke was detected from a passenger’s personal electronic device. The cabin crew brought the situation under control, and the aircraft landed safely at Rajiv Gandhi International Airport. Reports identified the device as a power bank, although IndiGo’s statement did not specify its type.

What happened on the Delhi–Chennai flight?

Smoke from the device prompted the crew to respond and the pilots to divert rather than continue to Chennai. News reports said the crew extinguished a fire in the cabin. IndiGo said it had arranged an alternate aircraft to take passengers onward and was providing refreshments and updates during the disruption.

Passengers and crew were reported safe, with no injuries reported in the accounts available. The safe landing in Hyderabad is confirmed; the airline’s announcement that it had arranged another aircraft does not, by itself, establish when every passenger reached Chennai.

Can you carry a power bank on an IndiGo flight?

Yes, subject to IndiGo’s battery rules and airport security clearance. A power bank must go in hand baggage, not checked baggage. IndiGo also says it must remain within the passenger’s reach—for example, under the seat or in a seat pocket—and must not be placed in an overhead compartment.

Under the airline’s published baggage policy, passengers may carry up to two spare lithium-ion batteries, including power banks, rated at no more than 100 watt-hours (Wh) each, subject to security clearance. Higher-capacity batteries have additional restrictions and require airline approval. Check the Wh rating printed on your power bank before travelling, particularly if it is a large-capacity model.

IndiGo says spare batteries should be protected against short circuits, such as by keeping them in their original packaging or separate bags and insulating exposed terminals. Its policy also says power banks must not be charged aboard the aircraft or used to charge another device during the flight. If your cabin bag is taken for check-in at the gate, remove the power bank first and keep it with you.

What should you do if a battery starts smoking in flight?

Alert cabin crew immediately if a power bank or other device becomes unusually hot, swells, smells of burning or produces smoke. Do not hide it in a bag or attempt to manage a smoking battery on your own. Follow the crew’s instructions so they can use the aircraft’s fire-response procedures.

The diversion of 6E 6115 illustrates why power banks belong where a developing problem can be noticed quickly and reported to trained crew. The flight landed safely, but the incident disrupted passengers’ trip and led IndiGo to arrange another aircraft for the remainder of the journey.
