HI,
I mentioned this in another thread, but it's probably worth highlighting properly.
At the moment - if you open a migrant banking package with ANZ whilst in your country of origin, you can be upgraded to 50kg baggage allowance with Emirates when you book one way flights. Unless you're booking first class anyway, in which case you won't need it you lucky things.
You need to send them a copy of your passport showing your visa after booking, and they will upgrade the allowance. This doesn't apply to infant allowances, but it does to all adults and children on the flight.
Chris.
