Giles- understand what you are saying but was led to believe that all LTN Ryanair based a/c this summer were not operating W patterns-stand to be corrected though.

This is only a rough guide as the timing is a bit out on some.
Thursday Kaunas flight is down as afternoon departure meaning 5 arrivals late at night-unlikely- so will probably go to a morning departure.
Assuming Kerry is daily, Tuesday ,Wednesday and Sunday have slots for something else unless they transfer some of the remote flights back to LTN based a/c
