Pros: Not much really. Check-in was helpful

Cons: Very poor seating and food. No amenities in “business”. Disembarked by bus. Baggage delays. And, awful everything single use plastic and useless packaging. Such a waste and not all what one would expect from a Nordic company, even on a low cost. Same can be achieved with environmental friendly ways. Shame shame shame.
