It is true that if you put Athens as the departure airport you do get offered Chania as a destination but if you then search the timetable between March and October it shows no flights available on every day? Is this just a problem for me? Can anybody else see seats available?
I also find the last sentence of the Chania Post article linked by Mouche a little odd:
"To celebrate this route, we are releasing seats for sale from just €16.99 for travel until the end of January 2020, which must be booked by Sunday (10 Nov). Since these amazing low fares will be snapped up quickly, customers should log onto www.ryanair.com and avoid missing out.”
How can you book a seat to travel up to the end of January 2020 when the flights do not start until March 2020 and how can you book before 10 November when today, 9 November, they are not shown as available?
