How far in advance are Ryanair timetables normally confirmed? Planning for travel to southwest Ireland in spring 2023 noticing that some schedules all end around 23rd March (Man - Snn, Man - Kir, LPL - ORK) but others are already in the system (Man - Ork, Man - Dub., LPL - Dub) what are the chances that it is not yet confirmed if these services will continue past this date?
