LX is cutting LHR from BSL due to the BD sale, but is starting LCY with own equipment. Other routes are reduced (FCO) or cut (MAN, BUD, CPH) in order to free up the aircrafts necessary for the new flights.

I assume there will be some shifting in the LH network as well (unless they have spare capacity).
