Michael, I’ve flown KLM on 2 different occassions, LAX-AMS-ATH. Mind you, these were back in ’89 and ’91, respectively, so that was a while ago. The service was good, comparable to a TWA, Lufthansa or United (don’t recall if the food was as good as United’s). Nowadays, I would definitely favor Thai over KLM, mainly because of my loyalty to the Star alliance. Back then, I had no choice!
