This was my first venture with Qatar. I have been flying with Emirates in the past. It was a very comfortable flight both ways. On the outgoing flight ie Nbo to CPH I upgraded to Business class and it was very pleasant and comfortable. The only negative thing was that at JKIA they did not let me access the lounge. The on board service is fine with acceptable food. It is very evident that on the leg from Doha to Nbo they use much older aircraft with none of the nice features of the newer ones. As an example the inflight entertainment is poor on the Nbo leg compared to good on the European leg.
