IndiGo Flight From Bengaluru to Lucknow Returns After Hijack Threat Note Found Onboard

IndiGo Flight 6E 451 Returns to Bengaluru After Hijack Threat Note

A routine flight from Bengaluru to Lucknow took an abrupt turn on the evening of Saturday, November 7, 2026, when a handwritten note found in an aircraft lavatory forced an emergency return to Kempegowda International Airport. IndiGo flight 6E 451 had been in the air for approximately 30 minutes when a passenger discovered the message, which explicitly claimed the aircraft would be hijacked at 6:30 p.m.

The Times of India reported that the crew immediately alerted the pilot-in-command, who in turn notified Air Traffic Control to request priority clearance for a return to the origin airport. According to flight-tracking data cited by The Hindu, the aircraft remained airborne for 51 minutes before landing safely back in Bengaluru.

Emergency Response and Security Protocols

Upon landing, the aircraft was directed to an isolated bay, a standard procedure for security threats that allows authorities to contain potential risks away from terminal infrastructure. The Hindu noted that airport authorities declared a full emergency as the plane touched down. Personnel from the Central Industrial Security Force (CISF) and the Bengaluru police cordoned off the area, while bomb disposal squads and dog units were deployed to conduct a comprehensive sweep of the cabin and passenger luggage.

IndiGo confirmed that all 178 passengers were deboarded safely in accordance with standard operating procedures. The airline’s spokesperson stated that the safety and security of customers and crew remained their top priority, adding that ground staff provided refreshments and regular updates to passengers while the security assessment was underway.

The Investigation into the Hoax

By late Saturday night, authorities had officially declared the threat a hoax. A senior police officer confirmed to The Times of India that the thorough search lasting 90 minutes yielded nothing suspicious. Despite the resolution of the immediate emergency, the incident triggered a formal investigation.

As reported by India Today, investigators are currently reviewing the passenger manifest and examining cabin access logs to determine who authored the note. The message found in the lavatory reportedly read, “This flight is going to hijack at 6.30, ignore and see the consequences,” according to The Hindu. While the emergency status has been lifted, the identity of the individual responsible for the disruption remains unknown as of late Saturday.

A Pattern of Aviation Security Concerns

The incident involving flight 6E 451 occurred during a week marked by multiple aviation security challenges for IndiGo. India Today highlighted that just one day prior, on Friday, November 6, another IndiGo flight—6E 6091 from Delhi to Chennai—was delayed after a similar caution note was discovered in a rear lavatory. That incident also resulted in the aircraft being returned to the bay for security checks, where it was subsequently cleared as a hoax.

Additionally, reports from India Today noted a separate recent incident on a Delhi-to-Pune flight where a passenger was booked for allegedly tampering with an emergency exit mechanism shortly after take-off. These events have intensified the focus on onboard security protocols and the logistical strain that hoax threats place on airline operations and passenger travel schedules.

Operational Impact and Next Steps

For the 178 passengers on flight 6E 451, the Saturday evening journey was delayed significantly as the aircraft underwent mandatory security clearances. While the airline indicated that the flight would resume its journey to Lucknow once the requisite approvals were granted by authorities, the incident serves as a stark reminder of the zero-tolerance policy maintained by Indian aviation regulators regarding security threats.

As of late Saturday, the investigation into the origin of the note continues. While the threat was ultimately determined to be non-credible, the legal consequences for individuals found responsible for such hoaxes can be severe, involving potential criminal charges for causing public alarm and disrupting essential services.
