I have an upcoming flight ADL-SYD-LAX booked as a single ticket with QF. I noticed the connection time in SYD (QF746 to QF17) is only 70 mins, which seems impossible to make considering the need to change terminals (even with the "seamless" transfer). Appreciate any thoughts/recent experience and whether QF would be willing to move me to an earlier domestic flight at no charge. Thanks.
