FNC is not a new winter destination from NCL, it was only last winter that the destination was not served, due capacity cuts from charter operators. It had been a feature of the destination list for a good few winters prior. SATA have also operated for a number of years from NCL, mostly during the winter, but a few years back did operate a summer service. Aircraft was initially 734, now usually A32x. With times like those I suspect it is a UK operator flying the flight as normally, a foreign based carrier would operate inbound before outbound, however ferry/posn flights are always possible.
Hope this helps?!
