They seem to be combining alot of flights for the winter, the LBA flight goes via Nottingham East Midlands on the Inbound.
Going via BHX in/outbound in NCLs case is a strange one, can anyone see the point of doing MLA-BHX-NCL-BHX-MLA from the airlines point of view? Surely they could get the BHX passengers on and off in one go, on the aircrafts return from Malta, like the LBA flight does when it comes via NEMA.
