Looking to book a DONE5 with the following route: CAI-SHA-DEL-KUL-BKK-AKL-SYD-LAX-MEX-SAO-DOH-CAI.

The first leg (CAI-SHA) is routed as CAI-AMM-DOH-SHA through the oneworld site. Called into the Qantas RTW desk to see if CAI-DOH-SHA is bookable due to CAI-DOH having domestic A class availability on the date requested. Agent said they use the oneworld site to view availability so no luck there.

Anyone have experience booking something similar?
