Thank you for your email.
Kindly be advised, 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 additional baggage allowance of 20 kilos, per passenger(adult & child from London/Manchester only).
This additional baggage allowance is only granted on your first use of the visa hence our requirement for it to be unstamped, the visa will be verified by our check-in staff on your day of departure.
You can have as many items of checked luggage as you wish provided:
The total combined weight of all the items put together does not exceed your total checked allowances
No single item of baggage exceeds 32 kilos in weight, as a health and safety requirement
If you are not holding the correct visa mentioned above at check-in, then you will be entitled to the standard free checked baggage allowance of 20 kilos per passenger.
The excess baggage charge is SGD80.00 per kilo equivalent to GBP40.00 approximately.
We hope the above information helps with your enquiry.
Thank you for your interest in flying Singapore Airlines.
