Bookings can only be made for train journeys that start at Brisbane Airport. If you are travelling to the Airport you must purchase your ticket from a CBD station before boarding the train.
All CBD train stations are operated by Queensland Rail which is a separate entity to Brisbane's Airtrain.
Your CBD transfer can be used for any of the five stations in central Brisbane including: Bowen Hills, Fortitude Valley, Central Station, Roma Street & South Brisbane.
If you are booking a return CBD ticket, Airtrain does not require the date and time you will be returning to the airport.
If you are not returning on the same day, you will be issued with an open-dated ticket when you arrive.
