You well may be right. It does look like LS have pulled the plug on the MAN-FAO route probably to concentrate as sole operator on BLK-FAO.
Should this be the case, I cannot say that I am totally surprised. There are quite a few operators on the MAN-FAO route and I personally feel that their flight timing was less than ideal for a single daily operation to this destination. Whilst I have no idea if the route was a commercial success during the past summer whist operated by a B757, they did seem to suffer quite a number of rather lengthy delays.
