Several foreign airports have US Customs and Border Protection (CBP) Preclearance facilities, where you clear immigration prior to boarding your US-bound flight. I recently flew Aer Lingus from Dublin (DUB) to Boston (BOS), and Ireland is the only country in Europe to have such a facility.
I’ve been through these facilities several times before, but there were a couple of things I found strange, and I’m curious if anyone has any insights.
But here’s what I can’t make sense of — all bags had to be placed onto an x-ray machine and be screened, while there was no metal detector or body scanning machine. So while all bags were thoroughly screened (including needing to remove laptops), passengers weren’t checked in any way.
A great solo travel tip spotted this week on One Mile at a Time.
