I've used travelconcierge before (twice now) and Roland has been very good at finding what I want and from different alliances. I think he is Australian based, but is very knowledgable in finding routings for me that work. ^
I used up *A miles for my first trip and this time I am using up my *A miles one way and BA/Avios miles on the way back. Being able to fly the A380 on Air France was nice.
