No, these cancellations were announced 37 days in advance in my case.

I am now on the flight I originally liked to book, but was more expensive at the time of booking.

When they offered to change my other flight segments, I also moved my second segment to Vietnam one day earlier according to my original intended schedule. Unfortunately I will have to apply for a new e-visa because my original visa is only valid from the original booked date. I did not think about this when I was on the phone with CZ and had to make a decision about all flight segments in this booking.
