Hello, my first post and am in desperate need of sound advice. We are booked for Cairns-Sydney-Santiago (Chile) in April. It is a Qantas booking but flying out of Cairns on Jetstar. On Friday, Jetstar changed the departure time which meant we would arrive in Sydney at 10.10am for an 11.35am international departure. We have not been able to get much sense out of anyone - we were told the Jetstar flight was an international flight so we were happy to go through immigration etc in Cairns rather than busy Sydney. Not so, we were informed when we tried to change our booking because of the delayed Jetstar departure time. It was a domestic flight leaving from the Cairns domestic terminal. The online chat person hung up after repeatedly saying just one hour is needed to get from Sydney domestic to international terminal, check in and get through immigration and security. I then spent an hour and 26 minutes on the phone, most of it on hold, to be told we only needed an hour in Sydney before the flight and was LIED to - "yes, our support desk will send you an email within 24 hours with assurance that you will be 'protected' should you miss the flight". As long as it was not our fault we should be fine. No email arrived in 24, 48 or 72 + hours. Last night we tried the phone again - 10pm until 11.46pm. The guy was helpful, agreed we would not make it on the Jetstar flight and changed our booking to a Qantas Link Cairns to Brisbane and then on to Sydney. We are scheduled to arrive at 10.10am (the same time!) but he assured me we would be better off as we and our luggage would be booked through to Santiago and we had an hour and 25 minutes to get to the international terminal and through security and immigration and to the departure gate. And 'you only need an hour'! Oh dear - out of the frying pan and into the fire! Have we compromised ourselves by changing the booking? Will this be our fault if we miss the flight? The QUESTION is - should we swallow our bile, abandon these tickets and fly to Sydney a day earlier and pay for a hotel overnight? OR will this jeopardise the rest of our booking if we do not turn up for the first leg? We have been loyal Qantas followers and what causes us the most stress is that apart from the guy on the phone last night, no one at Qantas (who we can access anyway) seems to care whether our itinerary works out or not! What do you think?
