Apparently they are going after Belgians and French customers as the RNS and ANR schedules are pretty useless for SEN-originating passengers:
...RNS at thrice daily, but with the first arrival at RNS not before 1355 (!) (departures from SEN at 1140, 1515, 1840)
...ANR at twice daily with SEN departures at 1550 and 1830
The aircraft will overnight at ANR and RNS and not SEN.
