Hi im flying singapore on the 16th sept, i rang to ask about double baggage allowance, but 457 doesnt warrent double baggage, they are giving me an extra 10kg and my husband the same when he flies in november. if your little girl has her own seat she will also have an allowance so you will be able to take extra that way, but you have to get it to and from the airport, so unless you are going with someone who will see you to check in , it may be a struggle with a 3 yr old. I wish you good luck with your move, i got top deck last year when i flew home from a holiday last year and if you can get that its a real bonus. i booked to late:sad:
