Interesting - and somewhat obvious - idea from Air New Zealand with the introduction of a wristband for children flying on their own with the carrier.
Any child passenger checking in for an Air New Zealand flight from this week with be given what the carrier calls an Airband for the duration of their flight.
The chip embedded in the device then automatically sends text notifications to up to five nominated contacts at important stages of the child's journey.
Air New Zealand claims it is the only airline to have launched such a service.
Airbands will be free for all children travelling alone until February next year, with bookings being given a £10 fee per child for each journey on a domestic flight and £25 per child on international trips from thereafter.
Stages when the device will trigger the text alerts at check-in, boarding, disembarkation and handing over to a member of ground staff and when they are met in arrivals by a designated adult.
ANZ's general manager for customer experience, Carrie Hurihanganui, says:
"We know that having your child travel on their own can be a nervous time for both children and their guardians.
"While our staff have always taken great care of children travelling solo, we identified that there was an opportunity to enhance the experience for kids while at the same time giving caregivers further peace of mind and visibility of their journey."
