What about SCL and DL? I can't find much mention about it in any threads but I know is a profitable route. There may be empty seats but there is a hell of a lot of cargo on those 767-300s. I remember non-reving SCL-ATL and having to use my last S1-R to get out on a half-empty -300. A groups of S3s got left behind and Business-Elite was empty.
What do you all know?
