IndiGo Agartala-Delhi flight diverted to Lucknow after cargo fire scare
Synopsis
IndiGo's Agartala-Delhi flight declared a mid-air cargo fire emergency on 15 September, landing at Lucknow in under two minutes — only for the alert to be cleared as a false alarm within 10 minutes. It is the second emergency diversion for IndiGo in five days, after a bomb-scare note triggered a separate diversion to Ahmedabad on 10 September, putting India's largest airline under fresh aviation safety scrutiny.
Key Takeaways
IndiGo flight 6E 6504 from Agartala to Delhi was diverted to Lucknow Airport on 15 September 2026 after the pilot declared a cargo fire emergency.
The emergency was declared at 6:29 pm IST ; the aircraft landed at 6:31 pm and all passengers deboarded by 6:35 pm .
The suspected fire alert was confirmed a false alarm at approximately 6:39 pm ; the emergency was withdrawn shortly after.
No injuries were reported; IndiGo's technical staff conducted post-landing safety checks.
The incident is IndiGo's second emergency diversion in five days — flight 6E 97 was diverted to Ahmedabad on 10 September following a bomb-scare note found on board.
IndiGo flight 6E 6504, operating from Agartala to Delhi, was diverted to Lucknow Airport on Tuesday, 15 September 2026 after its pilot declared a mid-air emergency over a suspected fire in the aircraft's cargo section. The aircraft landed safely and the alert was subsequently confirmed to be a false alarm.
How the Emergency Unfolded
The pilot declared the emergency at 6:29 pm IST, prompting air traffic control to initiate full emergency protocols at Lucknow Airport. The aircraft touched down just two minutes later, at 6:31 pm IST, and was parked at the bay by 6:33 pm. All passengers completed deboarding by 6:35 pm.
Safety personnel and emergency responders were positioned on standby as the aircraft approached. The suspected cargo fire alert was formally identified as a false alarm at approximately 6:39 pm IST, following which the emergency was withdrawn. The swift response — from declaration to all-clear — took roughly 10 minutes.
Post-Landing Safety Checks
IndiGo's technical staff were kept on standby to inspect the aircraft and certify its airworthiness for further operations. No injuries were reported among passengers or crew. The airline's ground handling teams coordinated the deboarding and subsequent assessment in line with standard aviation safety protocols.
A Second IndiGo Diversion in Days
The incident follows a separate emergency diversion just five days earlier. IndiGo flight 6E 97, operating on 10 September, was diverted to Ahmedabad after a crew member discovered a piece of paper bearing the word 'Bomb' inside the aircraft. That flight landed safely at Ahmedabad at around 5:40 pm and was carrying 107 passengers and six crew members, all reported safe at Terminal 2.
IndiGo subsequently arranged a replacement aircraft for the affected passengers on that flight, with the alternate service scheduled to depart at approximately 8:30 pm. Security checks were conducted in accordance with standard protocols following that incident as well.
What This Means for Aviation Safety Scrutiny
Two emergency diversions involving India's largest carrier within the span of a week are likely to draw heightened scrutiny from the Directorate General of Civil Aviation (DGCA). Notably, both incidents resolved without casualties — a testament to crew preparedness and established emergency procedures. However, the back-to-back nature of the events raises questions about the frequency of such alerts and whether systemic factors warrant a closer review. Aviation safety watchdogs and industry observers will be monitoring IndiGo's incident logs in the coming weeks.
Point of View
Even if both ended without casualties. The speed of the crew's response is commendable, but the DGCA will need to examine whether the cargo fire warning system on 6E 6504 malfunctioned and, if so, how widespread such sensor issues might be across the fleet. The bomb-scare note on 6E 97 raises a separate — and arguably more serious — question about cabin security and passenger screening. Back-to-back incidents of this nature, even resolved ones, tend to erode passenger confidence, and IndiGo's communications team faces a credibility test in the days ahead.
