I have a booking to CBR in October and with the schedule change was hoping for something similar as barboyz. This week QR called me from their European contact center in Poland to inform me about the schedule change and I started asking to change the flights. First the agent said any changes would cost me and only once I started complaing about the almost 3-hour schedule change she spoke to someone else to get advice. Then she allowed us to get off the plane in SYD on the way to Australia but didn't allow changing the return flight as the schedule change regarding that is only minor - so I ended having an open-jaw ticket.
