The airline will deploy a Boeing 777-200 LR aircraft for this additional flight, which will depart from Mumbai on October 25, Singapore Airlines said in a statement.
The South-east Asian carrier, which is the first airline to operate jumbo A380 to India, currently offers two daily flights to the city.
These flights are serviced by a combination of the Airbus A380 and Boeing 777-200 ER aircraft.
This additional flight will, however, return as non- commercial flight on November 2, the statement said.
At present, it operates A380 on the Delhi and Mumbai routes.
