[MENTION=438071]IanFromHKG[/MENTION] I agree with everything you’ve said however I can’t believe that $250 is accurate. CX has fares to HKG in Y for $A700 return sometimes. $250 pretty much wipes out the fare on the outgoing leg and I can’t see airlines every agreeing to that amount.
I have heard figures of around $50-75 which I think is more reasonable.
