Succeeded in getting a good award on the dates I wanted for 2 pax in Jan 2017 from SYD-TYO-LHR all the way in first.
Just hope that there will be no downgrade of aircraft type for the route (an upgrade of aircraft type is welcome

)
I was actually surprised that availability on JL is actually not bad after all the hoo-ha about CX availability.
Cheers!
