An interesting report, thanks. The US pre-clearance facility in DUB sounds ludicrous. I guess I can see some logic of doing it in Canada, where there are flights from major Canadian airports to many different smaller US airports that don't otherwise have CBP, but their more remote operations at DUB and Abu Dhabi just make no sense to me. I suppose it could result in fewer people having to be put on planes back to where they came from due to being denied entry, but surely in this era of entry credentials being checked electronically before you can board the aircraft that is close to a non-issue anyway?

Back to Aer Lingus for a moment: did you see what the non-upgraded economy class meals were like?
