Hi
New forum member so please be gentle.
My wife and I are flying to Australia from LHR this November and returning via multiple Asia stops. The numerous flights are with BA, Qantas and Cathay Pacific - all oneworldalliance members.
As we'll be covering many thousands of miles, what's the best way to make sure we get rewarded for them?
I looked at the BA website to join the exec club and they require a booking ref number. However, we booked through Travelbag.co.uk who arranged the multiple stop over flight and they cannot trace a BA ref number.
Any ideas?

Thanks
