I really appreciate everyone answering. Yes, we have had some pretty good luck with Immigration though even when the lines are short/moving fast, the kiosks are still faster.

As for Customs if there is no GE line, well, OK...I will give it a try (jumping to the head of the line). I can only imagine the reaction of those waiting in the long lines, and I hope the Customs people don't give me holy hell for it. I have terrible luck with those Customs guys. They always single me out! The last time was the worst. I was rushing home from Colombia due to a family emergency. Now granted, aging hippie w/ backpack...coming from Colombia...but I am a birder and I had the binoculars, bird books, etc. in the backpack. Even then, I got the third degree. He wanted to know why I was traveling alone (um, didn't want to ruin my husband's vacation because of an issue with my crazy mother), what kind of emergency (try explaining the crazy mother thing to a Customs agent)....I figured I was in for x-rays and laxatives...but fortunately, he let me go. Anyway, the point is that I somehow trigger suspicion even when I am dressed in business clothing. I always get pulled for secondary screening. So cutting the line is probably not going to work for me. But I will give it a try. My husband is going to Argentina today. We'll see how he makes out when he returns via MIA.
