From the 8th of December 2008, Airtrain is kicking off a 6 month
promotion for kids aged (5-14) to travel free between the Airport and
City stations when accompanied by a paying adult, subsequent to the
following terms.
Kids Travel Free on Airtrain
Details of the Promotion
There is no limit to the number of children that can travel free with a
paying adult. You can even take an entire school group to or from the
airport accompanied by a single adult.
The offer is only available between the Domestic and International
Airport stations and City Stations. The list of city stations is Central
Station, Roma Street, Fortitude Valley, South Brisbane, Bowen Hills,
Albion, Wooloowin and Eagle Junction.
You can still purchase child tickets at all other QR suburban stations
and only need to pay the cost of travel to the city, not all the way to
the airport.

Shame they still charge rail commuters more for a single journey, then
say home to station to CBD, then CBD to airport ...
If using the go card to Airport touch on, touch off CBD, touch back on
and touch off at the Airport. If you do as a single journey you pay
more ...
If you don't believe me check the TransLink journey planner.
