Daysleeper: I'd be interested to hear how long you had to transfer in Dublin?
Originally we had an hour scheduled but there was a change and I think we had around 45 minutes scheduled which worried the heck out of me ... I timed it and we were a shade under 20 mins from stepping off the connecting ATR to arriving at the boarding q for the transatlantic having had a bus ride and gone through the US border clearance. Really efficient.
