I travelled to Australia recently with an 11 month old baby. We flew with Singapore Airlines (direct on the way out and stopped off at Singapore on our return). The airline was fantastic and made that long and tiring journey quite 'painless'. The cabin crew were very attentive and extremely helpful with things like heating up milk and baby food and making sure all our needs and our baby's needs were met. The cabin crew were very friendly and seemed to love babies. The checking in process was quick and easy and the flights were on time. I would highly recommend flying with Singapore Airlines.
