Children travelling below the age of 5 must be accompanied by an adult aged 15 years and above.
Children above the age of 5 but under 12 years of age must travel as an Unaccompanied Minor (UMNR) if travelling alone, unless accompanied by a parent or guardian who is 15 years and above.
However teenagers aged 12 but below 15 years of age, can voluntarily request to travel as UMNR, if desired.
Bookings for UMNR should be made through the internet or via the Rex Customer Contact Centre on 13 17 13.
If you are purchasing your ticket through a travel agent, you will need to call the Customer Contact Centre to confirm that the flight can accept your UMNR request. For safety reasons, the maximum number of UMNR per flight is limited by law. In addition, Rex reserves the right to refuse the carriage of any UMNR at its absolute discretion.

An administration fee of $44.00 per minor per sector will be charged for UMNR travel. To change an adult booking to a UMNR booking and add UMNR details via the Customer Contact Centre, a $55 charge per minor per sector is applicable.

Please note that the sender and receiving adult information is requested at the airport. Both sending and receiving adults must have valid identification.
