It’s excellent to see that Air NZ has removed the default opt-in for travel insurance with their website sell process. They have replaced the opt-in with the big orange button below.
I’ve tested the process and there is no need to deselect the insurance. The amount of space dedicated to the selling of insurance seems a bit over the top, I guess because internal fighting meant trying as hard as they can to retain the revenue. The issue is that this will introduce/retain more pain to the sales process and thus reduce overall flight sales. Experienced travellers will learn to ignore it.
