An IndiGo flight travelling from Agartala to Delhi was diverted to Lucknow on Tuesday evening after a smoke warning was detected in the aircraft’s cargo area. The incident occurred on September 15, 2026, prompting the flight crew to follow precautionary safety procedures.
The flight, 6E6504, landed safely at Chaudhary Charan Singh International Airport in Lucknow at around 6:29 pm. According to airport authorities, the aircraft was carrying 103 passengers and six crew members. No injuries or other untoward incidents were reported.
After receiving the smoke warning, Lucknow Airport activated its emergency response arrangements. Fire and rescue teams, ambulances, medical personnel, security staff and other airport support teams were deployed as a precaution to ensure the safe handling of the aircraft and everyone on board.
The warning was reportedly generated in the aircraft’s cargo compartment while the flight was en route to Delhi. Sources said the cockpit crew suspected a possible fire and requested a precautionary landing at Lucknow. The aircraft was subsequently inspected by technical teams.
Reports indicated that no actual fire was found after the aircraft landed, with one report describing the warning as a false alarm. Technical checks were nevertheless carried out as part of the safety procedure.
The incident comes shortly after another aviation alert involving a Varanasi-Delhi Air India Express flight, which was also diverted to Lucknow earlier in September following activation of a cargo-hold smoke alarm. Preliminary checks in that case reportedly found no signs of smoke or fire.
The latest IndiGo incident did not result in reported injuries, and airport authorities ensured that passengers and crew received the necessary assistance after landing. The aircraft was subjected to further technical checks before the next steps were decided.
The incident highlights the aviation industry’s precautionary approach to smoke and fire warnings. Even when an alert later turns out to be a false alarm, flight crews generally follow emergency procedures because a potential fire in an aircraft’s cargo compartment can pose a serious safety risk.
Further details about what triggered the warning are expected as technical inspections and assessments continue.
