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.
