I read a few months ago that Srilankan has started operating a coach service for people traveling from Antwerp/Brussels direct to CDG Terminal 1. (using a Srilankan branded coach). Apparently this is offered at the time of booking. So my guess is that they are targeting passengers from Belgium and Holland for the CDG ones.
On the FRA ones I have noticed a long check -in queue at Colombo Airport last time I was flying out of there. A lot of German tourists are coming to Srilanka and the Maldives. Lauda and LTU fly into CMB on a regular basis now. So with the good inflight service on offer on UL I am sure they will pick up a full load each time. I will find out from an employee what the load factors are on the FRA ones.
incidentally they have started to offer Video Games (up to 16) from 1st October. Looking forward to checking it out when I fly in December
