Hi Bet
Most of the airlines (but check out the one you intend to use), give a 40kg baggage allowance to those emigrating with a
PR visa, you can only use this once though. Check with the airline concerned.
For those going on an SIR, we are flying with Singapore Air and they have agreed an increased baggage allowance, upto 30kgs per person, as we are emigrating but on a provisional/temp visa.
Also there are special migrant fares ( very expensive though) that give extra baggage allowance.
