Hmm.
I'm moving to HK in January and was considering flying with Oasis (as opposed to BA or CX). My future employer are providing me with a free one way econ ticket to HK. In terms of price a one way with Oasis in business class would be better value than a one way econ with BA or CX.
I reckon my future employers would strech to pay for a one way WT+ ticket though. So I guess dilema is go with BA WT+ (and getting all the Gold card benefits on the ground) or go with Oasis business class (but not getting any on ground benefits) but probably having a more comfortable seat in the air and having to deal with the various delays to the flights.
