An Air India spokesperson said alternative arrangements were made to fly passengers to Lucknow.
The airline stated that the cascading impact of flight diversions caused by heavy rains in Delhi also contributed to the decision to cancel the flight.
Further, the delayed arrival of diverted flights resulted in the operating crew reaching their regulatory flight duty time limits.
The replacement crew could not be immediately arranged due to the weather-related delays and disruptions, the airline stated.
It said the affected passengers were also provided with hotel accommodation to minimise the inconvenience. Full refunds on cancellations or complimentary rescheduling were also offered to them if they opted, it said.
