Thank you. Yes this is ticketed by Qantas. I tried to create CAI-DOH-HKG but the tool said that the first segment cannot be operated by QR, and I had to book CAI-AMM with RJ instead.

I contacted QF after the original ticket is confirmed and issued, and they tried to add another segment from AMM to DOH operated by RJ. I am able to see this segment on my PNR, however, it says ticket is confirmed but is not issued. From what I was told, QF is not able to reprice this ticket.. I am curious whether I need to call them to remove this unissued CAI-AMM segment, or just leave it as it is?

I may have to leave enough time for the layover in AMM to avoid any delays or the unexpected
