Despite several attempts with ample A/I class, I've never had a QF1/2 seat released on just the SYD-SIN vv leg. Also had numerous occasions where the agent couldn't see the same availability as EF (no I/A class) and they refuse to submit a request to the droid. Beyond frustrating but interested to hear if anyone has successfully had this leg released using the droid.
Was successful with 2 x QF LHR-SYD U class in May 2022 for April 2023 travel.
