To close the op we landed four hours late at DUB from YYZ, spent two hours in baggage hall searching for our now lost baggage and missed our NQY connection with no further flights available for 2 days.
Aer Lingus were very good and put us on a BRS flight, itself delayed by several hours, then cost us £350 for a taxi BRS/NQY at midnight.
What the percentage chances are of ever seeing our baggage again I would love to know but observing the sea of cases spread across the floor in DUB my expectations are low. I suspect the bags were lost in YYZ.
Respect to the staff at DUB handling some of those rude and arrogant passengers, difficult times indeed.
