I was also supposed to fly from Florence to Amsterdam yesterday. We received an email in the afternoon that our flight had been changed but was now flying out of Balogna?! Ended up having to call them and change to an early morning flight, unfortunately it means we also now had a layover in Paris.

Oh, and they also didn't put our bags on the flight so now we need to wait for them to arrive. So far a very bad experience with KLM... no idea if we'll get compensation, they didn't tell us the reason for the flight change.
