We leave Sydney at 8.55am and arrive at 3.45pm. We realise there is a time difference of two hours but this is 7hrs before we add the 2 hour time different as we are 2 hours ahead of Bali. Making it a 9 hour flight. The trip home we leave at Midnight and arrive home at 8.30 am. Which would be an 8 hour trip minus the 2 hour difference makes it approximately a 6 hr trip. Would this meant that our flight to Bali may be going via Melbourne. If this is so how do I find this out . It doesn't say it on the tickets. Thanks for your help . Gug
