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.

Pros: I've never been on a flight with such narrow seat and thin cushion. There was no entertainment offered for the almost 4 hour flight. There was no means of charging any electronic gears. The airplane seems to be 30 years behind time. Crew was unfriendly and smiling faces are not part of the uniform.
Cons: Very narrow seats and thim cushion. No entertainment offered an do means of recharging electronic devices.
