Looks like it is being sorted. The problem was the Cathay/OAG timetable contained duff information. We have booked SYD-HTI-SYD to keep within the 4 SWP segments as we are also doing SYD-PER-SYD.

I didn't realise that SYD-HTI was single class as the segments have been left "Open" but class is shown as "D".
