well, LH is far from being really well financially, though much better than any other carrier in Europe in terms of leverage.
Why would they want to change their livery?? It looks good, not a bit old-fashioned, and as LH tends to keep their aircraft pretty clean, I find it quite elegant (nothing like a LH coming out of a clear deep-blue sky, as seen from A5 coming from Darmstadt). That old "wellblech" look would probably look quite nice, though not on the whole fuselage, but please keep in mind the extra-weight of the paint, coating etc., that would have to be added.
Afaik, LH is working on a completely new coach, business and first class design, that should be realised from 2004 onwards.
I know it's only VfB but I like it!
