I've avoided flying across the pond with Lufthansa for years because of their sub-standard business class cabin. Just about all their A350s and A380s are 2-2-2 configuration, with no cubicles and not even a privacy screen between the pairs of seats. As a solo traveler, I prefer a solo, window cubicle with aisle access, as offered by the other biggies, UA, BA, AF, Delta, etc. LH really should be charging fares at the level of Iceland Air, with a sub-standard biz cabin, and not identical to the other carriers.
I've read online about Lufthansa finally becoming competitive by refurbishing their planes. So I booked a flight from DEN-MUC on an A380 that had a 1-2-1 config as confirmed by their seat plan and reservation system. 48 hours before the flight, they changed it to the old 2-2-2 garbage. At that point, there was nothing I could do about it.
I currently have another supposed 1-2-1 LH plane ticket for next Spring. I'm going to see if I can rebook that with another carrier. Fool me once shame on you, fool me twice, shame on me 😁
If you're picky about seats, like I am, be advised.
