Expedia allowed you to get all the way to the end and changed the cost. The total went up to $69,259 on the payment page. I went over to CheapOAir and booked the same trip for my family in June for two weeks and we got it for $6446. ORD to SFO is UA and then SFO to AKL is ANZ. We did a stopover in AKL for 4 days and then onto Sydney for another week and then home back to LAX to ORD on United Polaris. I checked with both Air New Zealand and United and all my tickets are booked and confirmed and I even selected my seats.
