We first revealed details about cheap Business Class seats as part of a news story in early April, but we thought this is something more people would be interested in so we've given it a headline of its own.

Most people who only fly domestically or for the occasional overseas holiday have never flown in Business Class. Due to Air NZ putting its Boeing 787 Dreamliners and Boeing 777-200 planes into service on flights between Auckland and Christchurch there will be premium seats available to domestic travellers.

Therefore curious domestic travellers who've always wanted to try sitting in Business Class (Air New Zealand call it 'Business Premier') will be able to grab a seat at the front of the plane for as low as a $30 premium on top of the domestic ticket price - meaning in some cases such a special seat can be booked for less than NZ$100.

The only downsides are that although you'll be in the specially designed business class seats (which technically can transform into a lie flat bed) - you'll not actually be treated to Air New Zealand's superb business class service or be provided with bedding for your short domestic flight. Sorry, no champagne, hot towels, free amenities pack or overnight nap!

In addition, Premium Economy seating is available for free to Air New Zealand's premium customers  - those with a Koru Club membership or who have reached Airpoints Gold or Airpoints Elite status.

There have been other times when Business Premier seats are available for domestic flyers to try - with some Boeing 777-200 used on schedules currently and in the past for a $50 premium to get put into a Business seat. And in years gone by Air New Zealand Boeing 747's also got a little usage domestically too.

It's also worth noting, if you happen to find the domestic flight you've chosen is using a Boeing 787 Dreamliner or Boeing 777, you'll be required to check-in 1-hour before the flight rather than the usual 30-minutes. This covers the extra time to get everyone onboarded - in some cases by bus and then external stairs up to the plane.
