So I just called QR who said they can't book a OneWorld Explorer ticket and referred me to the OneWorld website instead! Is there anyone who has had success in booking a OneWorld Explorer ticket that was issued by QR? If so, who did you use to book this for you? Separately, are there any downsides to booking a ticket on QR? I'm also curious as to why such a big difference in carrier charges arise depending on which airline issues the ticket.

On the assumption it may be challenging to find anyone who can book this ticket on QR for me, are there any other pointers you or others may have that could help bring the overall carrier charges and taxes down?

thanks
