While we all discuss if premium fares need a sub-forum or not I think it will be good to start posting some. (If already exists mods please move this post) This is a very good one on SQ 77W business. Only airline to fly this route non-stop... and in style on course! GRU-BCN round trip 3.260$ all in. Books in J (EOS). Refundable for a fee (100$). Cheers!
