The carrier, which quit long-haul during the pandemic, made a pre-tax profit of £109.5 million in the second quarter, following an £86 million loss in the first three months of 2022.
The airline said second quarter figures were impacted by higher fuel prices and the reinstatement of aircraft order prepayments.
“This quarter has demonstrated our ability to rapidly ramp up capacity and effectively meet the strong demand for air travel,” said Geir Karlsen, chief executive.
