Move to Singapore Krisflyer where that will be enough for two Saver Awards in Business Class to Euope from selected cities (ie Manchester, Amersterfam, Rome, Athens, Freankfurt, Instanbul).
One Saver J = 127500 (if booked online to gain the 15% discount) points plus fuel fines and taxes for Europe return.
Vietanam return is 87,500.
Points transfers at about 0.67 from memory. QF is at 1/1..but gives less value after transfer.
To build up think about swapping toa Westapc Krisfluer Amex/Visa
10000 points for signing on.
Amex earns at 1.5 Krisflyer points per $ and Visa 1.0 point per $
Caveat: look at where you want to fly and in what class before deciding.
