Hello all you people that know a lot about BA.

I need your advice, i am looking at an RTW ticket through NZ in november 2013..

From LHR to HKG i am offered three alternatives. Its all in Y.

BA0025 (Shows as aircraft may vary)

VS0200 (A346)

CX (several flights, but adds GBP 200 to the price)


So my question is wich one should i pick? We are a couple travelling, so i think Airbus, but BA does not charge for exit seats at OLCI right?

FYI we are both SA eurobonus members, so miles is out of the question for all flights i guess.

So overall, what would you reccomend to go with?
