The carrier posted a third-quarter pre-tax profit of NOK 169 million (£14.6 million) on Thursday (28 October), which compares to a loss of NOK 980 million (£84.6 million) during the same three-month period last year.
It is Norwegian’s second consecutive quarterly profit following completion of the reconstruction process in May, which saw it shutter its long-haul at Gatwick.
Norwegian said passenger demand was returning across all markets, while forward bookings "remain strong" leading into summer 2022. The airline cut its route network dramatically to focus primarily on domestic and Nordic routes, but is hopeful of re-establishing more European routes next year.
Nearly 2.5 million passengers flew with Norwegian during Q3, compared to around one million during the same period last year. Load factor was 73.1%, up 12.5 percentage points. It is currently operating a fleet of 51 aircraft.
"The third-quarter results clearly demonstrate the actions taken across the organisation to safeguard the future of Norwegian by lowering debt and liabilities, while focusing on cost efficiencies, have succeeded," said chief executive Geir Karlsen.
"We are now in a strong financial position going into the traditionally more challenging winter months. We have seen a positive trend in forward bookings month on month and an increasing number of passengers are choosing to fly Norwegian across our European network."
At the end of Q3, Norwegian had NOK 7.6 billion (£660 million) banked, with the carrier hailing its ongoing efforts to control costs and limit cash burn. "The stringent focus on costs and expenditure places Norwegian in a far stronger position over the winter months than previous years," it added in its Q3 results statement.
"Booking curves continue to show a positive trend well into 2022 as an increasing number of passengers choose to fly with Norwegian."
