No, should have said, separate bookings. Is it possible to combine on a single reservation a return to Singapore booked with Avios and 2-4-1 (in WTP) with a one way to Bali on Jetstar and a return to SIN on AirAsia? Not forgetting the Qantas returns also booked with Avios to Melbourne - one way in Business and back in Economy?

But thanks for setting me straight on the transit.
