So was looking at some Aussie prices and there's a fair bit of competition at present on flights to India with Qantas, Fiji Airways and even Malaysian. Had a look from NZ and pleasantly surprised - a lot of the cheapest dates are with Singapore Airlines! I've given example dates below, and note that some dates Fiji Airways or Sri Lankan Airlines might show up as cheaper, but if you have a preferred airline you can always filter using the options on the site.
