sadly only in German...
Anyway, the message of the article is that Lufthansa is starting to offer cheap oneway fares on domestic routes. Till now you had to pay for a full flexible Y ticket if you wanted to fly LH oneway, but under the pressure of the LCC's LH is dropping this strategy. From Friday evening till Sunday evening there is a restricted number of seats for 59€+10€ TSC available on each LH Domestic flight.
Generally a good thing, but the restriction on the weekend and on domestic flights is a bit annoying IMO. Nevertheless clearly a smart move into the right direction
