The reservation agent tried to get it to work but told me it failed as I could not mix cabins (BS considering every simple award search shows mixed cabin). She said she had to transfer me to to web support (I didn't ask). I had to start from scratch feeding the segments to the off shore agent but it priced out at 70K for him. My ticket was one way six segment trip from SIN-BOS with a mix of O, I & X class
