We normally pay about the $1500 price point, but it all really depends on the time of year you go, who has what sales on and a whole range of other factors! If you know when you are going, start watching prices as soon as you can with Skyscanner and the like, so you know when a good deal comes along. Last year, we got return via Auckland and Houston in PE with ANZ for cheaper than their economy seats on the same flights purely because there was a PE sale on! If you’re willing to do the extra flights, you can sometimes get a cheaper flight too.
