Hmmm interesting post as I always have trouble using OLCI. The strangest thing though, is that I am a CANADIAN Citizen but Cathay never lets me continue and will either give me no reason or this time when I'm flying direct to the States, it's asking me for ESTA. I'm guessing cause my Country of Issue for my Passport is in Hong Kong so they can't differentiate the difference?

Not normally a problem as I've been flying J most of the time, so lineups aren't that bad..however still a pain.
