Having used LH the so called 'airline of choice' (recognised carrier, safety record etc), for my work location for past 2 1/2 years on a fairly frequent basis (6 r/trips a year)
The only good thing I can say for LH business class is seating in 340's of 2+2+2;
Food is abysmal, service is grudging - they can't make tea and they frequently lose or damage my luggage primarily on way home so I don't get satisfaction!!! of compensation (apart from replacement cases)
Pre 9/11 used to be able to make outward trip in a oner, now rescheduled & have to nightstop FRA - they provide hotel if I'm on an inbound LH flight (so my company accountants insist I use the 'freebie') - but what a selection of mediocre flea pits they offer around FRA!!! - remember I'm on a full 'C' class ticket;
Am just about ready to incur delay's (6 - 8 hours in my case) etc of a transit via the Gulf (Emirates), but keep saying it should get better
