SAS has signed a letter of intent with CFM International for a 12-year Leap-1A services agreement.
The $180 million agreement guarantees the Scandinavian carrier's engine maintenance costs on a per-flight-hour basis.
In 2011, SAS selected the Leap-1A powerplant to power 30 Airbus A320neo aircraft. The aircraft will be delivered between 2016 and 2019, Flightglobal's Ascend Online database shows.
The aircraft order also includes 11 options.
