The app was hopeless today. I had a flexi refund ticket AKL to CHC, but no online ability to cancel it, or even to take a credit. Instead, I was told to call the 0800 number. No thanks. I ended up changing the dates (and even that took ages with the app crashing, (presumably due to demand). My PA will have to sort out cancellation later. I don’t get why they sell a refundable ticket then do t allow a self-selected refund option. Sigh.
