Everything went without a hitch. Our airline, New Zealand, did change the time for our return flight from Australia, but I was kept abreast of that. I brought my tickets 9 months in advance, so I was taking some risk, especially since I did not get flight insurance. For a total savings of $700 for two tickets, I felt it was a good risk. I also went in with both eyes open that I would loss my money if I changed my mind about the trip.
