Here is the formal announcement from NQY re. the increased DUB Schedule, to operate from mid-March, initially 4 weekly. As CS says it goes up to daily during the peak season, and looks like it will also continue into W16/17 (until Jan, presumably with reduced freq.)

Things seem to be going quite well at NQY :-) although not seen anything about Ops from Germany for next Summer (except the new 2 weekly Harp from HHN).
