EI's early DUB-AGP has had the A330 everyday for the last number of years now. LIS and FAO was only once every so often during the Summer last year and for a few Summer schedules in the last few years. NCE was for two Summer schedules three and four years ago as far as I'm aware. And of course during the very busy Christmas Eve it has been used on occassion on WAW and LHR. But as has been mentioned above with the disposal of one A-330 (EI-ORD) they've no back up in the event of technical cancellations or delays. Though to be fair I think most airlines would be working all aircraft during their peak season.
