LH is and wants to be profitable - with all their subsidiary (look at LX). So I think the focus is on LHR as a hub.
Germanwings (LCC subsidiary of LH) should be merger with someone but right now no one is there: TUIfly maybe mergers with Air Berlin, Condor (wants to stand alone but will face difficult times without a partner) and Eurowings (also partner/subsidiary of LH) are the candidates.
