We've been looking into flights/baggage allowance and have decided to fly with Singapore Airlines. Had remembered reading that they gave a special migrant baggage allowance of 40kg for permanent visa holders. Emailed them to check and got this reply:
MIGRATING TO AUSTRALIA
Kindly note, if you hold an unused/unstamped/not validated migrant visa that specifically states that you are permitted to remain in Australia indefinitely/permanently, you will then be entitled to the double (40 kilos, per passenger).
The double baggage will only be granted when you check in at the airport when this visa is sighted and checked that it has also not been travelled on before, this has to be the first time it is being used.
We didn't bother getting our visa label put in our passports but upon reading this it sounds like we might have to to prove it's unstamped.
Has anyone flown with Singapore and experienced this?
