Some believe the complimentary upgs are going away. However others, as I, believe that is just circumstance since DL is standarizing their 767-400 fleet to BE to be able to move mor AC around the system. Since this is a heavy cargo route, they need the 767 and will are just tooting thier horn that it is now BE. ATL-LIM is does not get a lot of Premium traffic, and probably lives on cargo.
