Jetstar is selling limited $7 fares today to promote its new Wellington-to-Queenstown route in a bid to further breach Air New Zealand's hold on the domestic market.
The 90-minute sale starts at 9am for a route the bargain airline will begin flying on December 22.
Jetstar is also opening up a twice-weekly Sydney-Queenstown flight and increasing existing Melbourne and Auckland services to Queenstown.
House of Travel executive Brent Thomas said that although the fares were great for travellers, all domestic players knew the bargain-basement fares were unsustainable. But they would make a point.
"Obviously it's not going to be sustainable at ridiculously low prices, however what it does do is create demand. It grabs attention and creates awareness of a service which they therefore hope to get benefit from longer term.
