I've used a relative's account once. There's no English site. They have awards similar to Delta in that it's not so set. Iirc, the prices vary for different partners, but I could be mistaken. You can fly ow to Hawaii on Delta for 12.5k coach. (No yq on that flight) Cheapest between US and Brazil is 70k economy I believe. Flights originating in Brazil are not allowed to have yq. I don't know about other regions though. Practically speaking, if you don't speak Portuguese, it may be difficult to work with.
