My fiance and I are looking at booking a flight in October from the states to Auckland. We want to start in Auckland and rent a car making our way down to the South Island. My original thought was to book all the flights together, IAD-LAX-AUK and Christchurch/Queenstown-AUK-LAX-IAD. However, I am now leaning towards booking the flight from Christchurch/Queesntown to Auckland separately, staying an extra night if the flight doesn't line-up. Also, booking the flight from Dulles to LAX at another time to try and catch a deal as well. I'm wondering if its better to book now or wait closer to the month to book a flight? I read that October is a shoulder season and shouldn't be as busy, but not sure when I should book?
Any suggestions would be super helpful!
