I have priced up a trip on matrix and am having issues trying to use the power tools to take me to BA to book. I have read separate section on flyertalk under ita matrix and that highlights others having similar issues trying to book through BA. My very basic question is if I can get a price on matrix can I call BA to book manually using the fare construction details at the bottom. I cannot create on BA own website as it only shows a couple of options for the legs from and to LHR which are not the ones I want to take. The booking is multi legs and over around 5 weeks so perhaps too complex for the power tool?

LHR-PER
PER-BNE
BNE-ADL
ADL-SYD
SYD-LHR

I would stop in each of PER, BNE and ADL for a week and SYD just a day or two at the end.

Apologies if this is the wrong place to post.
