IndiGo Diverts Delhi–Chennai Flight 6E 6115 to Hyderabad After Suspected Power Bank Fire Triggers Mid-Air Safety Scare in India

An IndiGo flight from Delhi to Chennai diverted to Hyderabad on 11 October 2026 after smoke emerged from a passenger’s personal electronic device. Flight 6E 6115 landed safely at Rajiv Gandhi International Airport, where the airline arranged an alternative aircraft for passengers continuing to Chennai. IndiGo said the pilots followed established safety protocols, while cabin crew brought the situation under control. Preliminary reports suggested that a power bank may have caught fire, although the airline did not confirm the device’s identity or the precise cause. The incident highlights the operational challenges posed by lithium-ion battery failures during air travel, particularly when smoke appears inside an aircraft cabin.

Hyderabad Diversion Disrupts Delhi–Chennai Travel Plans

The diversion turned a scheduled domestic journey into an unplanned stopover for passengers travelling between two of India’s busiest metropolitan markets. IndiGo confirmed that the aircraft landed safely in Hyderabad after the pilots responded to smoke from a personal electronic device. The cabin crew contained the situation, and the airline arranged an alternative aircraft to complete the journey.

The incident also exposed a practical concern for airlines and travellers: a small battery-powered accessory can create a significant operational disruption when it overheats or catches fire. Although the aircraft landed safely, the diversion required additional ground handling, passenger communication and onward-flight arrangements.

According to the airline’s statement, it offered refreshments and updates while working to minimise inconvenience. However, the available information did not establish the total delay, the number of passengers affected or whether anyone suffered injuries. Those details should remain unconfirmed until the airline or relevant authorities release further information.

What Happened Aboard Flight 6E 6115

Flight 6E 6115 was operating from Delhi to Chennai on Sunday, 11 October 2026, when smoke was detected from a passenger’s personal electronic device. The pilots diverted the aircraft to Hyderabad under established safety procedures, and it landed safely at Rajiv Gandhi International Airport in Shamshabad.

IndiGo’s statement did not identify the device or confirm the precise cause of the smoke. Initial reports suggested that a passenger’s power bank may have caught fire, but this detail was not confirmed in the airline’s account. Maintaining that distinction matters because the device’s identity, battery condition and location could influence any subsequent safety investigation.

Passenger accounts described a frightening experience inside the cabin. Reports indicated that people initially struggled to understand what was happening while crew members worked to control the situation. The airline subsequently arranged another aircraft for the onward journey to Chennai.

The following table summarises the information available from the airline’s statement and the reported operational response.

Why Lithium-Ion Batteries Require Attention

Lithium-ion batteries power many everyday travel essentials, including smartphones, tablets, cameras and portable chargers. Their high energy density makes them convenient for travellers, but damage or internal failure can create a serious fire hazard. Under certain conditions, a battery can enter thermal runaway, a process involving rapidly increasing heat and potentially further cell failures.

The International Civil Aviation Organization (ICAO) has highlighted the risks associated with lithium-battery fires in passenger cabins. Its June 2025 regional safety advisory discussed incidents involving suspected power banks stored in overhead compartments. The advisory warned that battery fires can intensify rapidly and may require specialised response procedures.

Battery failure can result from several factors, including physical damage, internal short circuits, manufacturing defects and overheating. A device may also become hazardous after being crushed or subjected to other mechanical stress. Consequently, travellers should avoid carrying visibly damaged, swollen or unusually hot batteries.

Importantly, the cause of the IndiGo incident remains unconfirmed. The available information does not establish whether the device was damaged, defective, overheated or improperly stored. Any explanation beyond the reported smoke would therefore be premature.

New Power Bank Rules Reshape Air Travel

The incident occurred against a changing international regulatory landscape. On 27 March 2026, ICAO introduced revised technical requirements limiting passengers to two power banks per person and prohibiting their recharging during flights. The measures also recommend against using power banks to recharge other portable electronic devices onboard.

IndiGo’s published baggage guidance reflects these precautions. The airline instructs passengers to carry power banks in hand baggage, keep them within personal reach and avoid using or charging them during flights. Its guidance also prohibits storing power banks in overhead compartments or checked baggage.

These provisions are particularly relevant because a battery problem can develop without warning. Keeping a power bank accessible allows passengers and cabin crew to identify unusual heat, swelling or smoke more quickly. It also reduces the risk of a battery remaining unnoticed inside inaccessible baggage.

The following comparison outlines the principal requirements relevant to passengers.

Travellers should check the airline’s latest rules before departure, particularly when carrying multiple batteries or high-capacity equipment. International standards and individual airline instructions may impose different conditions on particular battery categories.

How Cabin Crews Manage Battery Fires

A lithium-battery incident requires more than simply extinguishing visible flames. Damaged cells can continue generating heat and may reignite after the initial fire appears to have subsided. Consequently, aviation guidance emphasises cooling, monitoring and appropriate handling after the immediate hazard has been controlled.

ICAO guidance describes procedures for battery and portable-electronic-device fires, including continued monitoring for renewed smoke or flames. It also warns against moving a device while it displays dangerous signs, such as active flames, smoke or unusual sounds.

For passengers, the essential response is straightforward: alert cabin crew immediately if a device becomes unusually hot, begins swelling or emits smoke. Travellers should not attempt to handle a burning battery themselves or conceal the problem inside a bag.

In the IndiGo incident, the airline confirmed that its crew controlled the situation. However, it did not publish a detailed account of the firefighting procedure or identify the equipment used. The precise sequence of actions therefore remains unverified.

What Travellers Should Do Before Flying

The diversion offers a practical reminder for passengers preparing for domestic or international journeys. Portable chargers remain useful for navigating airports, accessing digital boarding passes and maintaining communication during delays. Nevertheless, their convenience should not override safe handling.

Travellers should inspect their devices before leaving home and avoid packing batteries that show visible damage. They should also keep charging equipment away from excessive heat and use products that meet applicable safety requirements.

During the flight, passengers should follow crew instructions and avoid charging power banks. Under IndiGo’s published policy, these devices must remain within personal reach rather than inside overhead lockers. Passengers should check the latest policy before departure, as airlines may revise their restrictions.

These precautions cannot eliminate every battery failure. However, they can help passengers reduce avoidable risks and respond promptly when something appears wrong.

Diversions Carry Wider Tourism Implications

An unscheduled landing affects more than the immediate flight. Passengers may miss connecting services, hotel check-in windows, business appointments or pre-booked ground transport. The scale of disruption depends on the length of the delay, aircraft availability and the airline’s ability to reorganise operations.

For tourism operators, even a short interruption can create additional coordination work. Tour companies may need to adjust airport transfers, while hotels could face late arrivals. Travellers with separate connecting tickets may also need to contact their onward carrier independently.

IndiGo said it arranged an alternative aircraft and offered refreshments and updates. That response provided a route towards completing the journey, although the airline did not specify the departure time or total delay.

Passengers affected by similar incidents should retain their booking details and monitor official airline communications. Those with onward flights should contact the relevant carrier as soon as a missed connection appears possible. They should also keep receipts for necessary expenses and check the applicable fare conditions and passenger-rights rules.

No reliable figures are available to quantify the financial cost of this particular diversion. Assigning a monetary impact without details of the delay, passenger numbers and operational arrangements would be speculative.

What Happens After the Incident

The next important questions concern the device involved, the circumstances surrounding the smoke and the measures taken to prevent a recurrence. Investigators may need to establish whether the incident involved a power bank, another electronic device or a separate battery-related failure.

The available statement does not confirm the battery’s condition, its precise location or the final findings of any investigation. Nor does it establish whether the incident resulted from manufacturing defects, physical damage or another cause. These questions require evidence rather than assumptions.

For the airline, the immediate priorities include completing the passengers’ journey, documenting the incident and cooperating with any relevant safety review. For travellers, the episode reinforces the importance of following battery restrictions even when devices appear to be functioning normally.

The key lesson is not to avoid portable electronics altogether, but to carry and handle them responsibly. Battery safety depends on sound equipment, appropriate storage, passenger awareness and a trained crew response. The Hyderabad diversion demonstrates why these precautions remain important throughout the journey.
