KOLKATA: An intense fight broke out on Monday between the crew members and a passenger of a Delhi-Kolkata IndiGo flight with both sides lodging complaints against each other for chanting a religious slogan, consuming alcohol on board, and instigating flyers. The flight was stranded at the parking bay in Delhi during a three-hour delay due to operational reasons.The crew accused the passenger, a lawyer, of creating disturbance while the lawyer alleged harassment and denial of basic services by the airline staff. Police said they were probing both accounts.An air hostess complained the flyer seated in 31D boarded the aircraft in an inebriated condition and began urging fellow passengers to chant ‘Har Har Mahadev’. As per the complaint, after take-off, he tried to hide a bottle of soft drink and smelled of alcohol. Questioned by the crew, he quickly gulped it down. The crew handed him over to security staff at Kolkata.The lawyer denied the charges and filed a counter-complaint. He said he greeted the crew with ‘Har Har Mahadev’ without knowing her religion. He insisted he didn’t drink onboard and had a bottle of beer at IGIA before boarding, for which he had a purchase invoice. An IndiGo official said the cabin crew informed them that the flyer was “unruly” and “drunk”. On the flyer’s complaint, the official said they were looking into it.
