AIRLINES
Many Airlines are approaching the Australian metropoles from Europe, Asia and Amerika on a daily basis. Coming from Europe the Jets still need to stop and refuel in one of the hubs in the Middle East or in Asia. Coming from Canada or the US you can do it in one-leg but many flights are stopping in Auckland New Zealand. Not the worst place for a stop-over.
