BTW, it could just be google translate, but the text seems to mention CAN and NKG as possible codeshare destinations.
As CAN is the main hub, I think that just means HEL-CAN by CZ, either to make it a daily in combination with current AY or to entirely replace AY on the route.
The mention of NKG is more odd - does it mean AY is going to drop it again just a year after opening?
Someone with better ability than me to read the text might want to take a look.
