Questions on adding infant to MH tix redeemed via Qantas

[the8guy]

I got a Classic rewards booking via Qantas and flying with MH. I rang MH wanted to add an infant to the booking but was told to ring Qantas as the tickets were issued by Qantas. Any idea if this is accurate? I was put on hold for too long when ringing Qantas so thought of verifying with any users who had similar experience. Ta

Yes that is correct.
Qantas is retailer selling the adult ticket and as the infant has to be attached to the adult, Qantas will add the infant to the booking and charge you the relevant infant ticket price

Thanks for clarifying. With redemption ticket, how much would an infant tix cost? I know normally itd be like 10% of the ticket price if buying but wonder how it works on redemption?
