I fly from New Zealand to Europe each year. As there are loads of *A operators in and out means get near enough to 12000 miles each way and some very good deals in most classes. Same applies from what I have seen Europe/New Zealand/Europe. Can go thru US/Canada or thru many places in Asia such as China, Hong Kong, Singapore, Bangkok. It is also possible to go thru South America as something different. LH does Frankfurt to Buenos Aries with Air NZ the next sector to Auckland and of course vice-versa.
