We were travelling on the 8th of December, 1 day after the bad weather (read "chaos") in Amsterdam. Incoming aircraft was delayed by almost 1 hour making us miss the connection in Amsterdam. Were automatically rebooked on the next flight AMS - FCO (which was also delayed by 1 hour) arriving at destination almost 5 hours later. Have filed a complaint on the KLM website and received a negative response several days later. After a few more phone calls to the PSL and one more angry e-mail, I still did not get anywhere:

Thank you for your further communication. I am sorry to learn that you are dissatisfied with the handling of your case. Please be assured that Customer Care analyzes in great detail each communication that is received (spoiler alert - they don't, I have proof from an earlier case). As mentioned in my previous email, your flight was indeed delayed because of the delay in the aircraft's rotation as a consequence of weather conditions.

Doesn't aircraft rotation go under the "airlines fault" category and isn't this a valid reason to get the compensation? I mean there is ALWAYS bad weather SOMEWHERE in the world and in this case KLM can tell 99% of their customers to go to hell, because their plane is stuck somewhere (not necessarily Amsterdam) due to bad weather conditions?!?

Thoughts on how to proceed?
