City-based chartered accountant Rachit Goyal, who was among the passengers, said they had already informed airline officials about the fog conditions in Chandigarh. Despite this, the airline operated the flight late and then diverted it back to Mumbai, leaving passengers to spend the entire night travelling. He said there were around 180 passengers on the flight.Another passenger, Manuj Sharma, said the situation led to chaos at Mumbai airport after the flight returned.
