The following prices are just taken from QR's booking engine. (19.00 AST.30 April)
This is an extract of the full result. The first itinerary is a pretty standard, but not cheapest, itinerary
The second is also for CPH-HKG showing a Business Saver ticket costs over 30% more than a FULL price Business Flex!
The third is for HKG-CPH and shows that a Business saver is 95% MORE than a business Flex. And Business Value is 106% more than Business Flex!.

I know that the different ticket classes can be sold out but can someone please explain how a lower class ticketing class cost so much more than a 'full price' ticketing class. Were I forced to take theses flights I know which ticketing class I would choose.
