Just curious whether other people share my experience clearing immigration and customs at SFO and LAX.

At SFO I have a consistently smooth and easy experience. I typically breeze through immigration and customs. It's easy to re-check your checked luggage, and the whole facility is a lot nicer than LAX.

At LAX I make it through immigration no problem, but am batting 1.000 with getting held up with customs. Maybe I look more suspicious when I travel via LAX - who knows. Half the time I get the dreaded red mark on the customs card and I have to go off to the side for special handling. This is never happened at SFO.

Anyone have similar experiences?
