I believe Dublin is scheduled for two XM'd 767 weekly flights featuring International J & Y. If you're dates are flexible, you may want to plan accordingly.
I regularly work those aircraft and outside of the absence of PTV's I quite like them (don't shoot me forum regulars). In fact two of the three are the newest 767's that we fly (recently leased from Hawaiian Airlines) the seats are comfy, large 777 type bins, extra lavatories. They actually smell factory fresh.
