We are going to visit friends in Perth & Sydney (and hoping to visit Cairns too) next Easter for one month (with our two boys aged 5 & 7). Does anyone have experience flying with BA/Quantas or Singapore Airlines on this route(eg food, inflight entertainment,staff, legroom)? We are also thinking of stopping over in Sinapore-any advice? Any tips/advice on any of the above would be very welcome!
