Auckland to Copenhagen, Denmark $1076 Return (Free Long Layover in Amsterdam/Guangzhou) on China Southern
China Southern is offering cheap flights to Copenhagen for $1076 return. This is the cheapest flight ever to Copenhagen and beats the last cheapest by $13. Fares include seats, bags and meals.
FYI these do involve an 18-hour stop in Guangzhou in one direction, but it is a daytime stop, and China Southern will give you a free hotel room to relax in while you wait. You can also go out exploring with China's visa-free transit. On some dates in the other direction, there is also a full day in stop in Amsterdam.
So good flight for the adventurous.
