We want to book return flights to Sydney via Singapore, that will also allow us to break the journey and stay in Singapore for a few days on the outward leg of the journey. I'm pretty sure this isn't an unusual thing to do, and I've picked up that it's called an "Open Jaw" flight (yes?). But we've visited the websites of several major airlines (BA, Qantas, Singapore Airlines) and a couple of flight comparison sights and can't see any way to search for it. They all just seem to advertise standard return flights. DH says we will need to go to a travel agent, but I'm not giving up yet ... what am I missing?
