A third A330-200 aircraft will be added in 2019 providing the opportunity to expand Level’s network further.
At Paris Orly airport, Willie Walsh, IAG chief executive, said: “We’re delighted to start flying from our second European city.
“Level is performing really well and ahead of our expectations in all markets.
“We will continue to invest in Level and are committed to accelerating its growth.”
In Barcelona, a third A330-200 will start operations in September and another one will be added next year totalling four aircraft in 2019.
Level currently operates from El Prat’s airport to Buenos Aires, San Francisco and Boston with a summer service to Los Angeles.
Level’s Paris flights are operated by IAG’s French airline OpenSkies which has transitioned into Level.
