I am a newbie who has lurked here as well as reading as much information as I can get. I need some help. 5 months ago I booked an award ticket on Star Alliance airlines to fly from IAD to SYD with a return from AKL back to IAD. I am now thinking about changing my ticket (if possible) in order to spend a few days in another city - Bangkok. I like my outbound flights and don't think there is anything that I can even change it to. My question is on the return can I do AKL to BKK (for a few days) and then BKK to IAD (via Narita)? I would like to book this as a round trip. Is this even possible? I apologize in advance if I have used the wrong terminology - feel free to gently correct me.
