Had an inoperable seat in Business Suite early January that stayed upright for my 11-hour flight. LH quickly fully acknowledged my complaint and apologised, as the purser also reported it. Still awaiting their compensation offer, while I’m close to hitting the 2-month mark for my complaint and getting ready to involve SÖP arbitration.
Funnily their last follow-up response was that I should reach out to D Telekom about the connectivity issue….
