Posted part of this in the dedicated thread as well, but I haven't received an answer so far, and my question has now expanded:

1. I'm having trouble parsing the fine print on whether I'm eligible for EC261 compensation for a cancellation, since my flight will now arrive at destination 2 hours earlier than the original time. Specifically: my itinerary was DEN-MSP-AMS-BLQ, and MSP-AMS was cancelled the morning of due to a technical problem. KL operated, marketed, purchased; the connection from DEN was DL operated. Eventually I was rebooked on UA/LH. Departure time was exactly 1 hour after the original time. Arrival time will be 2.5 hours earlier than the original time. I'm still in transit, so things could change. Does this fall under eligibility for a claim?

2. Regardless, can I claim some other type of compensation from KL? I lost all my original seat assignments in Y comfort, which were nicer than what I eventually got. I got them for free as Plat, but they've got to have some value. I also switched to Star Alliance carriers, where I only have Silver status. I'm killing over three hours of time at FRA with no lounge access. I've got to buy food that would've been free otherwise. And just in general, I lost any other type of assistance/attention/kindness that I could've received flying this whole itinerary as Plat on KL. Seems like I have a good case to request some compensation, no?

Thanks for any advice.
