Hi Hun, only Qantas and virgin Australia accept unaccompanied minors. Qantas do not charge any extra but virgin charge around $30 more each way. You need the name, address, phone number and relationship to. Hold for both the person dropping off and the person collecting. The air hostee will not release the child until photo Id can be shown by both. I book around 5 unaccompanied minors each week so it's pretty common. X
