The low-cost carrier on Thursday (18 July) posted third-quarter revenue up 11.4% to £1.76 billion and passenger numbers up 8% to 26.4 million.
During the three months to 30 June, passenger revenue increased 10.7% to £1.39 billion, while ancillary revenue rose 14.3% to £374 million.
The airline has also sold 78% of its summer seats, which has contributed to its positive outlook for the rest of the year.
Chief executive Johan Lundgren said the “robust” results came despite “tougher macroeconomic conditions”, and had been boosted by “solid” Easter performance and various “late yield initiatives”.
