Getting back to Richard Reid, since he did not pass the ICTS sniff test initially and was denied boarding, was it a mis-communication that he boarded the following day? I don't recall the full details, now that I think of it -- all I recall is he did not pass ICTS security, was re-booked, and flew the next day.

If one does not pass ICTS security on the first try, were they (American Airlines) really supposed to re-book him for the flight the next day? Perhaps he slid through the cracks with ICTS the next day by an ICTS employee that wasn't on the ball. If he did get a second chance, ICTS should also been aware of it on day #2.

Typically it doesn't take much for me to get through ICTS security (they can be annoying, though); however, I've seen some of the better ICTS employees effectively profile individuals at stations such as LGW which then sets the tone & content of the interview and any additional searches at check-in. ICTS protocol seems a bit different depending on European airport as well. MAD is the strictest I've ever experienced while in the UK & even AMS it is less strict (probably more strict at this point in time). FCO is stricter than LGW or AMS, but not as bad as Madrid.

Last but not least, do US carriers use ICTS / additional security in Dublin? Isn't there US Customs & Immigrations pre-clearance there, or is that just Shannon?
