So I was looking at flights to the New York in October for my 8 year old son and I, from New York we are flying onto another city on the east coast. We are exiting the States from Houston. So I entered a search into Air NZ website and it came up with a cost of $4,144 for both of us. So I entered the same search into google flights but included the final destination in and the cost of the flights came out at $2,313 nzd for both of us.
I am flying on the same flights from Christchurch to Newark and from Houston back to Christchurch, being Air NZ aircraft so how can the same flights have a difference in cost of $1,831 while also including two internal flights in the States? Hence to say that I have booked the flights through Google Flights what connected me through to United's website and completed the booking in NZ dollars.
