I cannot remember anyone having anything good to say about KLM
Sorry to disappoint you, but I have flown KLM several times in the last year, mostly with a transit at AMS. Intervals between flights have ranged from around 1h15 to 3h45. All flights arrived and left on time, and my checked-through luggage made it every time.
I hope this doesn't mean my luck has now run out and the next trip will be awful.....!!
By the way, if you do have time between flights at Schiphol, the satay chicken from Hot Wox in the Food Court is actually rather delicious.
