ANA Holdings Inc. plans to claim compensation from engine-maker Rolls-Royce Holdings PLC following its cancellation of more than a dozen flights last month after finding broken turbines on three 787 aircraft, according to two people familiar with the plan.

The form of compensation may be discounts on future purchases or free parts, rather than cash, one of the sources said, asking not to be identified before a final decision is made. The airline canceled 18 flights last month, with costs for the first nine cancellations estimated to be ¥55 million ($532,000), the company said at the time. The people didn't disclose the value of the potential claims.

ANA, the world's biggest operator of 787s, is changing the turbine blades on all the Rolls-Royce engines in its fleet of 50 Dreamliner planes after parts broke off on two international flights and one domestic flight. The issue is ANA's biggest with the model since a 2013 global grounding of the entire Dreamliner fleet, which led the carrier to cancel flights for more than four months.
