Photos from the flight showed plastic waste rammed down a lavatory and a crew member holding a drainage pipe stuffed with rags.
Flight diverted ‘without notice’
One man who claimed to be on the flight wrote on social media: “Apparently, the crew knew about it but decided to take off. Then the captain did not announce that the flight was returning back. Some passengers noticed it on the screen flight map and raised the issue.”
Another commenter said such incidents were not unusual, writing: “My mum once flew from New York to Delhi on an Air India plane that was leaking toilet water into the aisle. So yes, this is normal.”
Ajay Awtaney, an Indian journalist, said it “could also be a reflection of the people who flush stuff down the toilets that should ideally be in the trash”.
Air India described the incident as “embarrassing” and said its decision to divert the flight back to Chicago O’Hare International Airport was taken in the interests of passenger comfort and safety.
It added that it had helped passengers with hotel accommodation and alternative flight arrangements so they could continue their travel to Delhi.
“Who do we blame? Airline, passengers, or just a complete disregard in civil society for basic hygiene?” a spokesman asked.
