American Airlines has round-trip flights from Houston (IAH) to Sydney (SYD) for $753 with a connection. Flights February to mid-June. Holiday blackouts apply. An Australian ETA (a visa) is required.
Note: Be sure to pay attention to the time/date change during travel.
Note: Flights in April, May, and June require a long 5-or-6-hour connection on the return flight. The February and March flights have better connections, under 2-hours.
Note: There was a similar sale on this airline for $824 last month with better connection times in April, May, and June. There is a pretty good chance the airline will automatically change your routing to something better when it gets closer to your departure date, however, there is no guarantee that this will happen. Alternatively, if the airline makes any changes to your itinerary, you can them call and get them to change your flights to something with better connection times.
