DELHI- On September 1, 2025, an unruly passenger aboard IndiGo (6E) flight 6E 6571 from Indira Gandhi International Airport (DEL), Delhi, to Netaji Subhas Chandra Bose International Airport (CCU), Kolkata was taken into custody upon arrival.
The cabin crew reported that the passenger reeked of alcohol, misbehaved with staff, and disturbed fellow travellers.

IndiGo Passenger Misbehaves with Attendant
The flight experienced a three-hour delay on the tarmac in Delhi due to operational challenges.
During this time, the passenger—identified as a lawyer—allegedly urged co-passengers to chant the religious slogan “Har Har Mahadev”, creating tension aboard.
When questioned by crew members after take-off about a concealed bottle of soft drinks (suspected to contain alcohol), the passenger reportedly consumed its contents quickly.

IndiGo’s Protocol and Response
The airline confirmed the passenger seated on 31D was declared “unruly” in accordance with aviation protocols and was handed over to security at CCU on landing. IndiGo emphasized its zero-tolerance policy for disruptive behaviour, committed to maintaining a safe environment for all
Further, the largest carrier in India added that the airline has a zero-tolerance policy towards any form of disruptive or abusive conduct and remains committed to ensuring a safe, respectful, and inclusive environment for all customers and crew.
The flight was scheduled to take off at 7:30 pm on September 1, but with the delay, it took off at 10:30 pm, finally landing in Kolkata on the following day at 1:09 am.

Passenger’s Defense and Legal Claims
The passenger, however, filed a counter-complaint, denying that he had consumed alcohol onboard, while asserting that he had consumed only a beer at Delhi airport before boarding.
He also presented a purchase receipt as proof. In sharp contrast to the claims of the crew of Indigo, the passenger in question maintained that he greeted the crew with “Har Har Mahadev” without any religious intent and felt targeted.
He also claimed the crew failed to provide basic services during the delay, neglected to serve food, and threatened him when he recorded videos and sought explanations; he cited financial losses of around ₹4.8 lakh due to the delay.

Bottom Line
The passenger also claimed that the crew kept flyers inside the aircraft for more than three hours without a pilot and did not serve food during the delay.
He further claimed that the air hostess, alongside another flight attendant, had threatened him with dire consequences.
Bidhannagar Police in Kolkata confirmed receiving complaints from both the airline crew and the passenger.
