Yesterday, Air New Zealand started charging for Airband.
Airband are electronic bands that are worn by children traveling alone with Air NZ.
The bands were introduced in November, but were free until now.
Bookings made from February 3rd will incur a fee of $15 per child for each one way domestic journey, or $40 per child for each one way international journey.
The technology was thought to be a world-first in the air travel industry.
Have you ever worn an Airband?
