I remember asking about the liklihood of something similar to this before but Jamie2k9 stated the earliest Aer Lingus would start new long haul routes would be circa 2012/13.
That was when EI were getting A330 in 2013 but since converted to A350 which are not due until 2015.
Regaruds to European routes EI don't have right aircraft but EZY do.
