I have not flown KLM for years. I was recently forced to fly KLM in Y for some personal trips and came back very impressed with their service in Y. The seats and food were excellent. I flew SFO-AMS-AMS and other long haul segments from AMS and was uniformly impressed.

I definitely recommend KLM in Y to HYD over LH. I have flown LH a lot and there is no comparision between KLM and LH in Y. LH J was decent and I don't have a reference point for KLM but friends tell me that it is indeed an extension of their Y service.
