Norwegian will operate both its Edinburgh-Oslo and Edinburgh-Copenhagen routes twice-weekly.
The airline has been operating just eight aircraft on Norwegian domestic routes since April owing to the effects of the coronavirus crisis.

From July, the airline will operate 76 European short-haul routes from its Scandinavian hubs, flying to destinations in Spain, Greece and other key cities.
