I think for the price drinks should be included instead of charging for these. I didn't like mealtimes as the start and end of a 9 hour flight as it leaves a 9 hour period in between with no food. The touch screen was excellent and great leg room with friendly staff. The plane was modern and the engines quiet. A lovely aircraft (but the reading light up so high does shine into the seats all round). The touch screen and flight tracker was amazing. Trivia game was fun! More games needed.

We put in bids to upgrade to Premium on both legs, which were accepted, wish we'd known this was possible earlier as we'd already paid extra for baggage, seat allocation and food before the bids were accepted - never mind still worked out cheaper! Superb service, can't recommend Norwegian highly enough.
