Singapore to Perth. We were careful about our cabin baggage limit and whilst we had pre- purchased 25kg checked baggage knew we would exceed this and have to purchase extra 15kg. Earlier reviews prompted us to arrive early for check-in expecting queues. We arrived early to find a special "early check-in " queue. We checked in our 2 bags totalled around 30kgwe had bought 25kg but no extra charge. Slight black mark when our priority boarding status was not recognised and we were put in the wrong queue - sorted that ourselves. Flight was on time and very smooth cabin crew excellent.
