lovetravellingoz, that does look like an efficient use of points, and via the best carrier. But the t&f make me gag. Guess there's no way around them, or you, of all people, would have found it. LHR has the reputation for being the worst place to fly "free", but methinks your itinerary would provide a month's wages in your destination. Well, for your part, you'll probably offset it with what you'll pay for accommodation in Vietnam. That would work for me. (I used to spend a fortune to save one by travelling "free" to some exotic destinations, but now look at the whole picture...) So, on balance, "Yeh!"
