That's fair enough
SLF3, I was being slightly Devil's Advocate based on when this question has been posed before!
I have in the past also chosen sheer space of a biz seata above service (it was some years ago and the seat was not brilliant but there was SPACE and the service was SABENA long haul
) Mostly, people choose a combination of the factors but it certainly depends on whether it is a biz or leisure trip. I don't do long haul biz these days in my current job.
