My current 2-4-1 booking is an open jaw, booked outward online as soon as flights released, then phoned up three weeks later to add the return as it became available. No change fees, and no problems with the very helpful agent.
Oh that's great news as am considering SIN / HKG / BKK / KUL as options to fly back from so opens up a whole lot of options for potential return availability
