namdas Welcome to the forum
I would be looking at fares to a bigger city, like SIN, KUL or HKG then a separate tickets to SGN on who ever is cheapest/best schedule.

You can only get awards if you have miles/avios/points. From your post you seem to be more of a frequent spender (converting to ff miles) rather than a frequent flyer.

AA tend to have the cheapest long haul awards, if you can avoid BA (best earn/burn). AA charge cash surcharges on BA flights, but not other airlines. BA has high cash surcharges on award flights. Do not confuse real taxes with carrier imposed surcharges. But you are getting avios from non flying activities. Also look at IB avios. You can move BA avois to IB avois IIRC. Some here have reported awards from IB are better value.
