You need to fiddle about with it a bit and make sure that it gives you Business in the AA segments as it can give you economy.
So on the multi city tool book as follows:
Flight 1
GLA-BOS
Flight 2
BOS-LAX
Flight 3
LAX-BOS
Flight 4
BOS-GLA
I hadn't intended to go via JFK on the way back but it came up as an option all in Business so I took it for the extra 40TPs.
I have found for the Transcons that you get Business BOS-LAX easier than JFK-LAX.
Looks like this for the flight numbers in MMB:

Edited to add:
As part of the multi city Holiday tool I added the hotel at the same time. Hilton LAX and Yotel in Boston. As I like the beaches Hilton at LAX is fine for me and makes my late arrival and early departure easier. Plus a nice breakfast in the Qantas F Lounge pre LAX-BOS.
I'd love to know how to make this work ....... I tried and couldn't get the flights for under £25k!!!
