Feedback from LH by phone on this topic about 3 months ago was: we don't have enough planes. Management knows. More planes have been ordered....please continue to post feedback on App...

And you are right: punctuality is not on their list....I just don't trust them to be on time anymore so I am booking day before / morning after flights now, where I used to just book same day. I missed so many meetings....and the additional cost/time is not just lost in the ether....
