I reckon they might even switch the HHN rotation to a KIR based airplane. I think there would eb time between rotation 1 & 2 to Dublin.
Might not use the HHN plane or they could add a HHN - UK or Poland route to replace it.
Ya the times fit almost perfectly with a Hahn rotation in the morning and a London rotation in the evening. So it looks like the aircraft will be operating KIR-DUB-KIR-HHN-KIR-DUB-KIR-LON-KIR-DUB-KIR. The London airport is not clear but will probably be Stansted (I can't see them increasing Luton from 3 weekly todaily in one go) replacing the evening rotation by a Stansted based aircraft.
