I don't want to get side-tracked into a discussion on Dublin, but the Tuesday and Saturday flights are cancelled there in the latter half of September and October.
As you point out, WOW's scheduling can be very reactive, so it's probably a case of Watch This Space for November.
Completely agree that 4x weekly was an insane level to launch Cork. The Wednesday flights in particular had rubbish loads. If it was just Monday and Friday, it might have done OK, but there are probably all sorts of routes all over the world where that statement applies.
