The carrier posted a Q1 operating loss on Friday (3 May) of €303 million, down a further €185 million on Q1 2018. Its shares fell 3% during early trading.
Unit revenue, meanwhile, fell 1.9%, the carrier said, due to a late Easter and substantial winter capacity growth throughout the industry.
And while unit costs decreased 0.4% at constant currency and fuel, this was “more than offset by unit revenue, fuel bill and currency headwinds” said the carrier.
Passenger numbers grew 3% on a load factor down 0.3 percentage points, while group net debt declined €403 million to €5.8 billion.
