I managed to watch the rest of the film on my new screen. But to be honest it was a bit inconvenient with all the wires etc in the cramped economy seats.
I wouldn't say theoretical seating worked because there were very few people on the flight so no-one really had any unwanted neighbours. The Easyjet flight to Copenhagen that left a few hours before might have been a different story.
Managed to use my Eurobonus points to buy a drink on board. Never going to have enough for a flight reward, so may as well use them up.
Tea and Coffee are free on SAS even in basic economy, so they trump BA there.

On arrival the Metro to the city centre was 60DKK for three zones, easy to buy tickets right at the entrance and it's just a short well signposted walk from arrivals.
The hotel I had chosen was the Hotel Bethel, which was close to the central Metro interchange station Kongens Nytorv and the 'main drag' of bars and resteraunts on Nyhaven. I was forewarned that although Danish looks like you should be able to pronounce it, because it uses mostly the same letters as English, any attempt to do so is doomed. This was amply demonstrated by the Metro announcing the stops. It was not easy to match up the spoken word with the names on the map. The only word of Danish I attempted was tak!
