The airline, owned by International Airlines Group (IAG), linked the two capitals for the first time in 2017 with a successful summer season.
The demand for seats has prompted the airline to return to Cardiff Airport for the 2nd year starting 14th June 2018.
Iberia Express operated the service in 2017 with an Airbus A320 aircraft. The flight will operate on Thursdays and Sundays in 2018 until September.
