I have not flown LH C class, but just returned on UA (Sept 9th) from a roundtrip IAD-BRU on a 767/300 in C class. I was pretty dissapointed. The seats are rather narrow, the PTV was a nice feature, but the choice was downright lousy. The movies were ok, but the other channels were limited, at best. I hesitantly brought a cd player for the domestic legs, and ended up using it over the ocean, instead of watching the PTV's. And believe me, I am a big PTV fan. Also, on both legs, the food was just ok. Flight attendants were NOT friendly at all. Perhaps the seats are better on a 777. Overall, it was not the worst flight or anything like that, but I certainly thought it would be much better. I was going to write them a letter, but thought it sounded so trivial, compared with everythhing else going on.
