Since Jetstar flights sometimes hold a QF flight number, does that mean I can book a Jetstar flight for a *ONE* ticket?

I know normally code-sharing isn't allowed if the operating airline isn't a OneWorld member, but since Jetstar is owned by QF, is this an exception?

If someone can check the latest star file, it'd be much appreciated. (Better yet, post it here.)

The reason I'm asking is normally Vietnam is quite difficult to get to (if at all possible) under an Explorer ticket, but with Jetstar, it may become easier...

Thanks.
