Agree with the above.
LH I would rate the same as KLM, preferable if you want a Star Alliance flight for the miles. THey have daily flights to both Frankfurt (awful, avoid..) and Munich (a much better airport and in my opinion nicer than Schipol)
I flew LH (business) to Munich over the festive period. I have to say that the Business Lounge in Munich airport is the shabbiest I have seen anywhere, by a big margin. There is an air of triedness about the lounge which is in contrast to the rest of the airport which is quite nice. They have a separate lounge for Senator and First Class which I presume is better but the standard one is a joke. The only hot food on offer was sausages and mashed potatoes!
The seats on the long journey from Singapore do not flatten much (leaving a big kink in the middle) and all the family woke up with backaches as a result. My main meal on the outbound flight was really quite awful but on the inbound the food was nice.
The check-in clerk in Changi (a strangely stressed-looking and slightly hostile Malay gent) refused to put a fragile sticker on one of our checked items as, he said, LH don't provide them.
Given the cost, I think the service fell well short. Although my ultimate destination was in Germany, I think I will fly with another airline next time.
