Thank you for your replies! Friendly and honest information is just what I was after.

Thinking about the QF/BA comparisons just made me think of another idea, being those flat J's on BA codeshares.

Award availability at this stage doesn't seem too flash, so we may have to take the risk and book economy and request an upgrade. I know that there is a QF flight that codeshares and uses a QF plane to SIN and a BA plane to LHR. Are QF likely let us try for an upgrade on that BA codeshare flight with my points? I was under the impression that upgrades can only be done on pure QF flights, but I'm hoping that's just me misunderstanding the codeshare setup.

Given we'll probably stop for a day or 2 in Singapore, we could possibly go up and down to SIN on a QF Y and just do the SIN-LHR in the codeshare BA J.

Please do keep comments coming, either QF or BA seating is of interest.

Thank you!
