How to book mixed class JAL and BA redemptions with Qantas points?

Hi all, I’m trying to work out how to book the following in one ticket:

Flight 1: JL 772 - SYD>NRT
(Stopover for a few days)

Flight 2: JL 41 - HND>LHR

Flight 3: BA 15 / QF 2 - LHR>SIN>SYD
Alternatively JL 44 / JL 771 - LHR > HND > NRT > SYD with 4hr airport bus transfer which isn’t ideal

I’d like to use QFF points to book business class for JL41, but leave the rest as economy. Do I need a travel agent to book this? I’ve tried to use the Qantas site but it keeps showing EK, CX and BA operated flights for that HND > LHR route specifically.


Have you tried using the multi-city tool on Qantas website?
