EZY operated Rome in the past and dropped it, so I'd say unlikely. Has it been confirmed that EI are not bringing FCO back for the winter timetable?? With the A319, could this route, if not particularly viable this year be a profit-maker next winter??
In fairness, many airlines have tried the weird and wonderful over the past few years. Some destinations in my opinion were a little hopeful (Budapest), but the likes of Berlin, Munich, Prague, summer Toulouse, etc, all seemed reasonable. Just seems that many of us Northern Irish folk aren't that adventurous, and a summer holiday means two weeks in Santa Ponsa or Bodrum with the kids and Grandparents.... City destinations especially seem unpopular, such a shame...
