Here's a great fare if you find yourself in the Far East and needing to find a way back to Europe.
Lufthansa have a fare which I've managed to optimise to £1168 / €1325 going from Hong Kong to Copenhagen, round trip. You can use this Google Flights search to search around for dates to suit, but fares appear to be available for travel until the end of June 2019.
Not all the fares I found on Google Flights appeared to translate into Lufthansa's own site, but these appeared to still be bookable with a bit of tweaking of dates.
The sector between Hong Kong and Frankfurt is operated on their A380s which use a 2-2-2 configuration, but as it also books into P class you need to be careful about which programme you credit your miles into, as there is great disparity. For instance Aegean Airlines does not give any credit, whereas Singapore Airlines gives 100%. Check the full table of earnings here.
