I am trying to fly to Perth (PER), Australia and on UA.com is only bringing up connections through SYD or MEL with QANTAS which is not *A. TG/NZ/SQ which are *A carriers and fly to PER do not show as options. Do I need to book through calling or is it just not possible to book an 016 ticket. Previously this has not been an issue as I would book OAL but with the $15k spend requirement (in 2019 for 2020 1K) seeing if I can do my spend with UA but UA do not make it easy. I have no desire to fly QANTAS.
