I'm in the middle of a RTW trip and I've been having terrible security/immigration/customs troubles the whole way. I'm "clean-looking", not too young, am Star Gold, and have never been in any legal trouble whatsoever in my life. Still, I got SSSS in LHR and LAX, a long ordeal at customs in AKL, a lot of confusion trying to check in at SYD... I've also been unable to check in online for any of my legs.

Is there any way to find out definitively why this is happening, and more importantly, is there a way to get off whatever watchlist I'm on?
