HEL-JYV belong to the dreaded AY8XXX series, AY codeshares with a non-OW partner. AY minus benefits were recently increased, but rest of the OW carriers do not want to get their hands dirty with these flights.

HEL-TLL AY flights belonging to AY3XXX series should be bookable by contacting Exec club. Their redemption booking engine is quite weak with partner flights.
