Qantas has cut its transtasman prices in a flash sale for Australia-bound Kiwis with seats as low as $219.

Starting today, Australia’s flag carrier will offer discounted fares to the five largest cities across the Tasman for 72 hours.

Flights leaving Auckland to destinations that Qantas has recently connected – Adelaide, South Australia, and Perth, Western Australia – have been included in the airline’s price slash.

However, flyers will have to pay full fare for the return leg, which is not included in the sale.

The cheapest fares start from $219 one-way for tickets from Auckland, Christchurch and Wellington to Melbourne.

Travellers can book flights from the same three New Zealand cities to Brisbane for a flat rate of $249, Sydney for $259 and Adelaide for $329.

Flights departing from Queenstown to Melbourne, Sydney and Brisbane are also included in the sale, but at a higher price.

By stretching the wallet a bit more, travellers can book Premium Economy tickets during the three-day sale from Auckland to Brisbane and Sydney for $459 and $469 respectively.

One-way Business Class tickets to various destinations are also being sold for no more than $559.

Return tickets are not included in the sale.

In May, Qantas began stirring up competition in the Tasman by introducing two new routes to rival Air New Zealand.

A direct Auckland-Perth service was the first announced, with Qantas’ non-stop flights between the two cities restarting on December 8.

A second new international route out of New Zealand, announced less than two weeks later, will connect Auckland to Adelaide from late October.

Qantas was recently hit by a cyber attack in which more than 5.7 million people’s unique customer data was stolen by cyber criminals, generating concerns the leaked data could be used to commit financial fraud and identity theft.

However, a June on-time performance report by Aviation analytics company Cirium brought better news for the company.

Data showed Qantas ranked eighth out of the airlines surveyed for its timeliness – beating Singapore Airlines and our own national carrier in the process.
