Hey Gooner - you've stopped answer the other thread! Anyway, just to say that yes it is true that Airlines will give you more luggage allowance, if you call them and let them know in advance. But it is not a given, so perhaps you need to check it out at booking stage to make sure you can get it.
Not sure about which way round to fly to get more allowance. Had not heard of this, but of course this does not mean that it's not true. Perhaps someone else can help with this.
Have you guys been for your recci yet?
