DC to Auckland and then Sydney to DC
In December 2025 I am planning on traveling from the DC area to New Zealand around the 17th of December. Then I will be traveling on January 2nd from Sydney back to the DC area. I have about 600,000 cap one points and 220,000 amex, and 178,000 kisflyer. I am trying to book tickets for a family of five. What would be the best way to try and book business class tickets for all?
