"We are now in a strong financial position going into the traditionally more challenging winter months," Chief Executive Geir Karlsen said in a statement.

"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," he added.

Bookings have risen in response to vaccination and the relaxation of travel restrictions, and the company said it expects its available seat kilometres (ASK), a key capacity metric, to rise to 29 billion in 2022 from 18.2 billion in 2020.
