The sale is for flights, holidays, tours and cruises purchased between tomorrow and Saturday.
Helloworld's sale comes after return economy fares to Europe dropped below $1000 in deals last weekend, with a growing move by Kiwis to premium travel set to be boosted by business-class fares for under $4000.
Limited Air China flights to Rome were on sale for $999 at Flight Centre's Travel Expo for travel in the three months from March.
And China Southern Airlines was offering business class to popular European entry port Amsterdam for $3999 from May to mid-November. Business-class fares have often been double that, although they have been falling during the last two years.
China Southern also had return flights to London, typically the most expensive place to fly to in Europe because of government taxes, for $1249 return a person for travel in the same period.
The number of new airlines has not increased at the same rate as a year ago, however, there is a record number of international seats to fill so airlines and agents are in a cut-throat battle.
If all the existing carriers keep flying here Kiwi travellers can expect more great promotional deals. But airlines with less efficient aircraft or with options to fly more lucrative routes could review their operations.
