On my upcoming oneworld award, I have the choice of BA or QF from Bangkok to London. I have only flown on QF with old business class seats, but this route would have the Skybeds AFAIK. Never flown BA J but I get to try that on LHR-YYZ on the same trip.

I'd appreciate any comments about the seats and service on this particular flight. My understanding is that the QF seat is not fully flat like BA. Do both airlines serve a full dinner after takeoff or is it some kind of a lighter "supper" due to the late departure? I'm currently booked on BA 10.

Thanks in advance.
