You are violating this rule:
4(b) Travel must be in a continuous forward direction between TC1 ‐ TC2 ‐ TC3. Backtracking within a
continent is permitted except as follows:
Backtracking between Hawaii and other points in North America is not permitted.
KHI and SYD are in TC3 (which comprises Asia and South-West Pacific)
DOH is in TC2 (which comprises Europe/Middle East and Africa)
So your first two flights (KHI-DOH-SYD) are going TC3-TC2-TC3 and that is not allowed. Same again for your proposed HKG-DOH-KHI at the end
Because your first flight is with QR, you cannot use the on-line booking tool. But you can book:
- with QR as it’s the carrier of the first flight (it will have an office in Hong Kong)
- with AA, since you have a long-haul AA flight (DFW-SCL)
- with any travel agent
