I was going to go in March too, but it was a little cheaper in April. Usually we drive to Toronto for International flights and it's much cheaper, but the difference was so small to NZL that it didn't seem worth the extra stop. We only stop once to Auckland in Chicago. What's your itinerary? I haven't booked anything else except i know i want to spend most of the trip on the South Island. It was $3300 for 2 people round trip. Only 1 stop on the way there and 2 stops on the way back and the layovers are so short.
